- I have seen some controversy over whether DisplayPort to HDMI passive adapters count as "passive" or not, because they have an integrated circuit inside, so I want to comment on this point.
- - - Although DisplayPort sources support the direct output of TMDS-encoded HDMI signals, it sends them at DisplayPort's native voltage (3.3 V) with AC coupling instead of the DC-coupled 5 V used by HDMI and DVI. Passive DisplayPort to HDMI adapters have a conversion circuit inside them which converts the voltage of the signals from AC-coupled 3.3 V to DC-coupled 5 V, called a level shifter. This does not make it an "active adapter", because it is not decoding DisplayPort packets and converting the information contained into an equivalent data stream in the 3-channel TMDS format that HDMI uses. The initial signal received by the adapter is already in the 3-channel TMDS format used by HDMI, and the adapter has no effect on the digital values of the signals passing through it, and so does not "convert" or modify any information in the data stream. It is a simple voltage change for electrical compatibility between the two systems, and the circuit is powered by the integrated 3.3 V power line from the DisplayPort source. - - The only real impact this has (from an engineering standpoint) is that it places a hard limit on what speeds a particular adapter can support, which is why there are different "types" of DP to HDMI adapters which support different speeds. This is because the output of the level shifter circuit needs to be able to keep up with frequency of the input signal (i.e. it needs to be able to change between 0 V and 5 V fast enough that it can generate digital signals at the required frequency). As new versions of HDMI keep doubling the frequency of the previous version, the DisplayPort to HDMI adapters made for the previous version are not suitable for supporting the newer speeds, so a new adapter using upgraded circuits is required each time. - |

-
- Which Cable Type Should I Use?
- - -
- It's generally recommended to avoid using VGA for computer monitors when possible. While it does work fine for most situations, the image quality can be degraded depending on the quality of the cable, and it's relatively easy to damage the cable which often results in color channels dropping out and requiring you to wiggle the cable around, and eventually replace it. On the other hand, VGA can be useful in some situations for consoles, and for using computers/laptops on TVs, since it usually avoids the overscan problems seen with HDMI (where the desktop is cut off on the edges), as well as HDCP compatibility issues that consoles sometimes have.
-
-
- Between DVI, HDMI, and DisplayPort:
- -
-
-
- So HDMI and DisplayPort don't have better image quality than DVI?
- - -
- That's correct. Between DVI, HDMI, and DisplayPort, there is no difference in image quality when the same image settings are used. The difference is that HDMI and DisplayPort support a wider range of possible settings, so they can be used for situations that DVI can't be used for, like 4K 60 Hz or 30 bit/px color depth. But these extra capabilities don't make them any better at doing the other things.
-
-
- What about between HDMI and DisplayPort?- - Basically it works like this; DVI can do some stuff. HDMI and DisplayPort can do all the stuff that DVI can do, plus some more. But the stuff that they have in common with DVI, they don't do any better than DVI does, it's just that they have extra capabilities beyond that. If you don't have a monitor that actually uses those extra capabilities, then there is no advantage to using DisplayPort or HDMI compared to DVI. - - - At the moment, the vast majority of displays still fall within the capabilities of DVI, so HDMI and DisplayPort are only necessary if you want the extra features like inline audio, or for higher-end display formats like 2560×1440 at 144 Hz, or 4K. - - - -
- It's pretty much the same as between DVI and HDMI / DP, just between the different versions of HDMI and DisplayPort instead. There is no difference in image quality between HDMI and DisplayPort. They both produce identical images when the same image settings are used. The choice between HDMI and DisplayPort only matters if one of them (usually HDMI) doesn't support the full specs of your monitor. For example, some 4K displays only have HDMI 1.4 and DisplayPort 1.2. Since HDMI 1.4 can't do 4K 60 Hz, but DisplayPort 1.2 can, you should use DisplayPort. However, if the monitor has an HDMI version which does support 4K 60 Hz (like HDMI 2.0), then it doesn't matter whether you use HDMI or DisplayPort.

- - Which connections can support 120+ Hz? - -
-
- In order of preference:
-
-
- Which one should I use?- - (Note that the source device and the display must BOTH support the required HDMI / DisplayPort version. Connections will be limited to the lower version between the two. HDMI and DisplayPort cables themselves do not have "versions", though may have bandwidth limitations. See here for more details on HDMI and DisplayPort cable selection: HDMI DisplayPort) - - At 1920×1080 (2K): -
-
-
- - -
- A straight DisplayPort connection is the preferred option in all cases. - - At 1920×1080 if DisplayPort is not available, then use Dual-Link DVI. If Dual-Link DVI is not available, you can try HDMI as a last resort, but it is not guaranteed to work for 120+ Hz (it depends on the monitor; some work, some don't). HDMI 1.3 and above are capable of 1080p 120+ Hz, but not all monitors implement this capability, some are limited to 60 Hz over HDMI. - - At 2560×1440 if DisplayPort is not available, then HDMI can be used if the monitor and source both support HDMI 2.0 or above. If the monitor and source do not both support HDMI 2.0 or above, then it will not be possible to use HDMI for 120+ Hz at 2560×1440. In this case, it may be possible to use Dual-Link DVI by setting a custom resolution, but it depends on monitor support and is not guaranteed to work. - - At 3840×2160 without compression, DisplayPort 1.3 or 1.4 can be used up to 120 Hz. Frequencies higher than these limits (such as 4K 144 Hz) will require Display Stream Compression (DSC), only supported by DisplayPort 1.4 or higher. - - - Isn’t HDMI limited to 60 Hz? - -
- No, HDMI is not limited to 60 Hz. This is a common myth. Many 1080p 120+ Hz displays are capped at 60 Hz over HDMI, but this is a limitation of those particular displays, not a limitation of the HDMI standard. HDMI itself allows unlimited refresh frequencies, and this has been the case since version 1.2 in 2005. Please refer to the main article here.
-
- Can I use a DisplayPort to Dual-Link DVI passive adapter / cable?- - Conspicuous examples of such displays include the ASUS VG248QE, the BenQ XL2411Z, and the Acer GN246HL. All of these are 1080p 144 Hz monitors with HDMI 1.4a ports, but do not support more than 60 Hz over HDMI. However, other monitors like the ViewSonic XG2401, Nixeus NX-VUE24A, and Samsung C24FG70 do accept 1080p 120+ Hz through HDMI 1.4a. - - The refresh frequency limits of HDMI at some common resolutions are listed in the table here. HDMI 1.3 and above are capable of 144 Hz at 1080p, and HDMI 2.0 is capable of 144 Hz at 1440p. - - -
- No. DisplayPort to Dual-Link DVI passive adapters / cables do not actually exist. Even though most DisplayPort to DVI adapters you see for sale are labeled as "Dual-Link", all of these are fake, they are only Single-Link DVI adapters in disguise.
-
- Can I use an HDMI to Dual-Link DVI passive adapter / cable?- - The DisplayPort connector has 20 pins, which means it can be used as a Single-Link DVI-D port via a passive adapter. However, Dual-Link DVI requires 25 pins, so a DisplayPort connector does not have enough pins to emulate a Dual-Link DVI connection. The additional DVI pins on "DisplayPort to Dual-Link DVI" adapters are not connected to anything at all, they are just for show, for marketing purposes. It is nothing but a Single-Link DVI-D adapter dressed up to appear like a Dual-Link DVI-D adapter. - - -
- No, for the same reason as in the above section. HDMI to Dual-Link DVI passive adapters/cables do not exist. HDMI only has 19 pins, like Single-Link DVI-D. Even though most HDMI to DVI adapters you see for sale are "Dual-Link", all of these are fake, they are only Single-Link DVI adapters in disguise.
-
- I have a BenQ XL2411Z / ASUS VG248QE / Acer GN246HL or another 120+ Hz monitor with no DisplayPort input. What should I do?- - These HDMI to Single-Link DVI passive adapters may work for 120+ Hz if used from a DVI output (computer/source) to an HDMI input (display) because it acts as an HDMI connection when used in this configuration, and HDMI 1.3+ can support 1080p 120 Hz as mentioned previously, but this does require the monitor to accept 120+ Hz over HDMI, so it will not work on monitors like the BenQ XL2411Z or ASUS VG248QE, which are limited to 60 Hz on their HDMI ports. - - -
- Connecting to the display's HDMI input
- - - HDMI 1.3 and 1.4 can support up to 144 Hz at 1080p, but this will not work on all monitors. Some monitors such as the BenQ-Zowie XL2411(Z), the ASUS VG248QE, and the Acer GN246HL will not accept >60 Hz over HDMI even though they have HDMI 1.4a inputs. This is not because "HDMI is limited to 60 Hz" (it isn't), this is just a limitation of these particular products. - - On monitors that do accept >60 Hz over HDMI (such as the ViewSonic XG2401), you can use either a straight HDMI connection, a DVI to HDMI adapter, or a DisplayPort to HDMI Type 2 passive adapter (up to 120 Hz at 1080p). A DisplayPort to HDMI Type 1 passive adapter will be limited to HDMI 1.2 speeds (60 Hz at 1080p). - - Connecting to the display's DVI input - Single-Link DVI only supports up to 60 Hz at 1080p, so Dual-Link DVI is required for 120+ Hz. This means inexpensive DisplayPort-to-DVI or HDMI-to-DVI passive adapters / cables cannot be used, because DisplayPort and HDMI only support passive adapters to Single-Link DVI, not to Dual-Link. Almost all DisplayPort-to-DVI and HDMI-to-DVI cables / adapters have fake "Dual-Link" connectors on them, but don't be fooled; they are still Single-Link DVI adapters in disguise. DisplayPort and HDMI do not support passive adapters to Dual-Link DVI; it is physically impossible to create such an adapter due to an insufficient number of pins on the DP and HDMI connectors. - - If you are using a monitor that only has DVI and HDMI inputs (no DisplayPort) and also doesn't accept >60 Hz over HDMI (like the BenQ XL2411Z), then you must use the Dual-Link DVI input. If your computer does not have a native DVI output to connect to it, you must use a DisplayPort to Dual-Link DVI active adapter. - - Not just any DisplayPort to DVI active adapter will work. There are plenty of DisplayPort to Single-Link DVI active adapters, intended for multi-monitor configurations on some older AMD graphics cards (detailed here). Inexpensive DisplayPort to DVI active adapters are all Single-Link-only and will not work for 1080p 120+ Hz. True DP to DL-DVI active adapters are very expensive, and generally quite unreliable. They should only be used as a last resort. If you haven't purchased your monitor yet, don't buy one that only has HDMI and DVI. Look for one that has native DisplayPort input instead. - - DisplayPort 1.1 to Dual-Link DVI active adapter: Amazon US - DisplayPort 1.1 to Dual-Link DVI active adapter: Amazon US - Mini DisplayPort 1.1 to Dual-Link DVI active adapter: Amazon US - |

- - What's the difference between a passive adapter and an active adapter? (Preface) - -
- There are a lot of myths and confusion surrounding passive and active adapters, and there seems to be very little understanding of exactly what they are, how they both work, and how to identify them. Hopefully this article will help clear things up.
-
- Passive Adapters- - First, to make some general points clear since there is a lot of misinformation spread around: - Passive Adapters: -
- - From a technical standpoint, the difference between an active adapter and a passive adapter is in the basic principle of operation. Being able to tell the difference between a passive and active adapter isn't as simple as looking for external features like power cables, bulkiness, or cost. Some active adapters require power cables, but less complex ones can get enough power directly from the port. Some active adapters, like DisplayPort to VGA, can be very inexpensive, compact, reliable, and require no power cables, and for this reason they are often mistaken or mislabeled as "passive adapters". However, these external features are not the criteria which actually define whether an adapter is passive or active. - - - So what is the difference exactly? Well... - - - There are many different signaling formats, or methods of representing and transmitting the information that makes up a video signal. Each different interface (VGA, HDMI, DisplayPort, etc.) uses a different format; they represent the information in different ways. If you (as a system designer) want your device to be able to communicate information to another device which uses a different format, there are two ways for this to happen. You can design your device to be able to communicate using the other device's format (make it "multi-lingual" in a sense), or you can insert a third-party device between them to convert the information from one format to the other en route (a "translator" if you will). A passive adapter works via the first approach, and an active adapters works via the second approach. - - - - -
- A passive adapter works via the first approach described in the preface. As it turns out, the ports on your graphics card or laptop or other source device can output signals in multiple different formats. For example, DisplayPort ports are not just limited to sending DisplayPort signals; they can send signals in the HDMI or DVI formats if required. Of course, the only problem is that the DisplayPort port cannot physically morph itself into an HDMI port to allow you to plug in HDMI cables, so this is why the "passive adapter" is needed; the adapter does not do anything at all to the format of the electrical signal, it is just there to change the shape of the port to allow you to plug the correct cable in. When you use a DisplayPort to HDMI passive adapter, the adapter is not "converting" DisplayPort signals into HDMI signals. The electrical signals coming from the DP port are already in the HDMI format, the adapter is just changing the physical shape of the port.
-
-
- - - Since passive adapters don't actually do anything themselves, they will only work for some very specific combinations of ports which have been pre-designed with the ability to communicate in other formats. The table below shows which connections are possible using passive adapters: - -
-
- -
- This table is an exhaustive list of all possible connections that can be made using passive adapters between DP, HDMI, DVI, and VGA. If it is not listed above, it is not possible with a passive adapter.
-
- Passive adapter compatibility has nothing to do with analog and digital- - While output ports can send multiple types of signals, most input ports will only accept signals in their native format. For example, if your display has a DVI-D input, it will only accept DVI signals. This means that you can connect to it from a DisplayPort, HDMI, or DVI output port, because all three of those ports know how to send the DVI signals that the input port requires. - - On the other hand, if your monitor has a DisplayPort input, you can only connect to it from a DisplayPort source. Neither DVI nor HDMI output ports know how to send DisplayPort signals, so they cannot communicate with just a passive adapter. In this case, an active adapter would be required to convert one of the other signals into the DisplayPort format, since DVI and HDMI ports cannot output DisplayPort signals themselves. - - The only type of input port that will accept more than one format is DVI-I, which can accept both DVI and VGA signals. However, it is very rare for a display to have a DVI-I input. Almost all DVI ports found on displays are DVI-D. - - -
- Something important to notice about the table above is that the compatibility between formats has no relation to whether each format is analog or digital.
-
- Passive adapter compatibility has nothing to do with bandwidth- - DisplayPort outputs are capable of sending DVI and HDMI signals, so a passive adapter can be used to connect a DisplayPort output to a DVI or HDMI input. However, DVI and HDMI outputs are not capable of sending DisplayPort signals, so a passive adapter cannot be used to connect a DVI or HDMI output to a DisplayPort input. Just because "they're both digital" doesn't mean passive adapters can be used. - - DVI-I outputs are capable of sending VGA signals, so a passive adapter can be used to connect a DVI-I output to a VGA input. Just because "one's a digital standard and one's an analog standard" doesn't mean passive adapters can't be used. If your digital standard includes the ability to send analog signals when requested, then it's possible to use passive adapters to an analog standard, and that's all there is to it. - - People imagine that when one signal is digital and the other is analog, this makes it impossible change one to the other without some processing involved, making passive conversion impossible. Meanwhile if they are both digital, they are more closely related and this makes conversion very simple (insert hand-waving here). - - This talk about how easy or difficult it is to convert one signal to another is irrelevant here. Converting one signal to another is what an active adapter does. Passive adapters do not convert any signals. Yes, it is impossible to convert an analog format into a digital format without any processing. That's because it's impossible to convert ANY format to ANY OTHER format without processing. There is no such thing as "passively converting" a signal. It doesn't matter whether it is analog to digital or digital to digital; ANY kind of signal conversion is impossible without an active adapter, period. - - Passive adapters work because source ports can output video in multiple different formats, so no conversion is necessary. These formats do not have to be related in any way. If you want to know whether or not you can use a passive adapter for a certain format, the answer has nothing to do with the port's other formats. - - For example, if you want to know whether or not DVI ports can support passive adapters to VGA, DVI being a digital format doesn't have anything to do with VGA adapter support, because the DVI format isn't being used when you're using a passive adapter. The correct question is, "are DVI ports capable of sending VGA signals instead of DVI signals?", and the answer is "yes, if it's a DVI-I port". Thus, passive DVI to VGA adapters are possible, despite the DVI format itself being digital. - - Likewise, if you want to know whether DisplayPort to VGA passive adapters exist or not, asking "is the DisplayPort format digital or analog" is completely irrelevant, because there aren't any DisplayPort signals involved when a passive adapters is used. The question is "are DisplayPort ports capable of sending VGA signals instead of DisplayPort signals?", and the answer is "no", so DisplayPort to VGA signals are therefore not possible. It has nothing to do with the DisplayPort format being digital, DisplayPort simply wasn't designed with the ability to alternatively send VGA signals, while DVI was. - - There are no rules of thumb, like "digital to digital is possible passively, analog to digital isn't". The compatibility of passive adapters is completely arbitrary and just comes down to what capabilities each video standard was designed with. - - -
- Another surprise to most people is that DisplayPort 1.2 doesn't support passive adapters to HDMI 2.0, or that DisplayPort and HDMI don't support passive adapters to Dual-Link DVI, only to Single-Link DVI. Upon being informed of this, the response is usually something along the lines of "well that doesn't make any sense; they're both digital, and the bandwidth of DisplayPort is greater than Dual-Link DVI / HDMI 2.0, etc. so a passive adapter should work!" But again, this is based on a misunderstanding of how passive adapters work.
-
- Passive adapters are not necessarily limited to the lowest common denominator- - People imagine that a passive DP to DVI adapter is "converting" DisplayPort signals into DVI signals, as if the image is originally sent as a DisplayPort signal and an adapter transforms it into an equivalent Dual-Link DVI signal, which should work because any Dual-Link DVI data stream will "fit" inside a DisplayPort signal since the bandwidth of DisplayPort is greater than that of DL-DVI. This is all very sensible sounding, and is a wonderful description of how an active adapter works, not a passive adapter. - - A passive adapter does not "convert" a signal from format to another. The original signal is sent in the desired format to begin with, and the adapter is just changing the physical shape of the port so that the correct cables can be plugged in. In a DisplayPort to DVI (or HDMI to DVI) passive adapter, the DisplayPort output port is essentially used as a DVI port; all of the pins are used to send the same electrical signals that a DVI port's pins would (more or less). Of course, the DisplayPort port is still shaped like a DisplayPort port and so DVI cables will not fit—that's what the passive adapter is needed for—but electrically it is acting as a DVI port. But a DisplayPort port also only has 20 pins (compared to 19 pins on SL-DVI-D and 25 pins on DL-DVI-D), so it can only send signals that a Single-Link DVI port would send; it is physically impossible for it to send Dual-Link DVI signals in this manner, because it simply doesn't have enough pins to send the same signals that a DL-DVI port would. HDMI ports (which have 19 pins) are also subject to the same restriction; they can only send Single-Link DVI signals, not Dual-Link. - - And again a similar concept applies to DisplayPort to HDMI adapters; many people are perplexed when they discover that DisplayPort 1.2 only supports adapters up to HDMI 1.4. "But DP 1.2 has more bandwidth than HDMI 2.0!" Yes it does—but since adapters don't work by "converting" DisplayPort signals into equivalent HDMI signals, it doesn't matter if HDMI 2.0 signals "fit" inside a DisplayPort 1.2 signal. The bandwidth of DisplayPort is irrelevant, because there are no DisplayPort signals involved at all. DisplayPort 1.2 only supports adapters to HDMI 1.4 because the DisplayPort control chips are not designed to send HDMI signals greater than that (mostly because DisplayPort 1.2 was published in 2009 and HDMI 2.0 didn't exist until around 2013 or so). DisplayPort 1.3 (2014) does support passive adapters to HDMI 2.0. - - -
- Another bit of seemingly sensible wisdom which turns out to be not always true is that when using a passive adapter, you'll be limited to lowest capabilities of the two interfaces involved. For example, if using a DVI to HDMI adapter, many people will tell you that audio won't work. After all, DVI signals contain no audio, and converting an audio-free signal to the HDMI format won't make audio magically appear. But again, this is based on the idea that an adapter "converts" DVI signals into HDMI signals, so this is information that applies to active adapters, not passive adapters. When using a passive adapter from a DVI source to an HDMI display, the output device detects an HDMI display and sends HDMI signals to it, including audio. Whether DVI signals contain audio or not is irrelevant, because there are no DVI signals involved. The adapter isn't "converting" DVI signals into HDMI signals, the signals are sent in the HDMI format to begin with.
-
- Do passive adapters add any latency?- - While it is sometimes true that you'll be limited to the lowest capabilities between the two interfaces, it isn't always true. Check the specific adapter combination you are wondering about using the dropdown interface at the top of this guide. - - - No.
-
- Do passive adapters reduce image quality?- - No.
-
- Active Adapters- -
- Active adapters (or "signal converters") use the second approach described in the preface; both the source device and the display send/receive signals in their native formats, but there is a device in the middle (the adapter) which converts the information from one format to the other. Active adapters are required for any combination of ports that isn't possible with passive adapters (as listed above). Active adapters have also been used in some situations historically to circumenvent limitations of passive adapters; for example, some older AMD graphics cards could support up to 6 monitors, but only maximum of two could be using DVI/HDMI signals (including sending DVI/HDMI signals through a DisplayPort port via a passive adapter); the rest had to use native DisplayPort output. DisplayPort to DVI/HDMI active adapters were useful in this case to allow additional DVI/HDMI connections, since the graphics card would send native DisplayPort signals, which were then intercepted by the adapter and converted to the DVI/HDMI format en route.
-
-
- Do active adapters add any latency?- - Active adapters have a processor which converts between the two formats, so they are more expensive than passive adapters and may require a power cable, depending on the complexity of the conversion. Since active adapters convert information from one format into its equivalent in a different format, they are limited only to the features and capabilities supported by both formats. This means active adapters won't support anything that isn't supported by both sides of the connection, including limitations on maximum bandwidth, audio support, and any other features such as G-Sync or daisy-chaining. In addition, certain active adapters may have their own limitations depending on what the signal processor can handle. For example, many (but not all) HDMI to DisplayPort active adapters are limited to 1920×1200 at 60 Hz. Even though both connections can go beyond that, the processor used inside those adapters can’t process data quickly enough to do more than that. For 1440p or 4K resolutions, even more expensive adapters with more powerful processors must be used. - - - Active adapters usually only work in one direction. An active adapter that receives a VGA signal and converts it into HDMI usually isn’t equipped to receive HDMI signals and turn them into VGA instead. When purchasing an active adapter, read the product description carefully. - - - In theory, any signal can be converted to any other signal with an active adapter, although in practice there is not an adapter manufactured for every conceivable combination of ports. - - - -
- Depends on the adapter, but usually they do not add any meaningful amount of latency.
-
-
- Do active adapters reduce image quality?- - -
- No. But when converting between two different formats the image quality will only be as good as the worse format.
-
-
- How can I tell if an adapter is passive or active?- - -
- Some people think that "active adapter" means it has an additional plug for power, but this is not the case. If an adapter needs a power cable, it is definitely an active adapter, but if it doesn't need a power cable, it could still be either an active or a passive adapter. It is not possible to tell the difference between them by looking at them, because "active" and "passive" aren't defined by any external feature, as explained above. Some active adapters may have conversion circuitry so small that it can be powered from the port and embedded in the cable termination, so that it appears just like any normal passive adapter cable.
-
-
- Which type should I use?- - Sometimes it isn't possible to tell whether an adapter is active or passive, but there are some steps you can take to rule out one or the other. Only specific combinations of ports are possible with passive adapters, listed in the table a few paragraphs above. If the adapter you are looking at isn't a type listed on that table, it must be an active adapter (or fake). If it is a combination listed on that table, then it could be either passive or active. Usually the product description will tell you, but if it doesn't, you should generally assume it is passive, because companies don't normally make active adapters for port combinations that can already be done using passive adapters. - - - However, there are some exceptions to this. Even though DisplayPort supports passive adapters to HDMI and Single-Link DVI, there are many active adapters also available for these combinations due to restrictions on multi-monitor configurations on some older AMD graphics cards (see here). So DisplayPort to DVI adapters or DisplayPort to HDMI adapters may either be passive or active; reading the product description will usually tell you. - - - In addition sometimes active adapters may be required between DisplayPort and HDMI depending on which versions you want; for example, DisplayPort 1.2 does support passive adapters to HDMI, but only up to HDMI 1.4; to get a full HDMI 2.0 connection from DisplayPort 1.2, you need an active adapter. - - - More specific information on what combinations are supported with passive adapters can be found by entering a specific combination of ports in the dropdown menus at the top of this guide. - - - -
- If a passive adapter is possible for the configuration you want (check using the utility at the top of this guide), then usually you should use the passive adapter. Active adapters tend to be more expensive and less reliable, and only exist for situations where passive adapters won't work.

› | -- Active Adapter Requirements for Multi-Monitor Configurations - | -[Link] | -
-
- Certain older AMD graphics cards require a native DisplayPort connection or DisplayPort active adapters to connect more than 2 monitors. DisplayPort to Single-Link DVI active adapters are useful in this situation to avoid the cost of an active Dual-Link adapter. This limitation ONLY applies to certain older AMD graphics cards. NVIDIA graphics cards have never had this limitation, and newer AMD graphics cards also no longer have it, so these cards DO NOT require DisplayPort or active DisplayPort adapters for any multi-monitor configurations.

-
- Do HDMI cables have versions?
- - -
- No, HDMI cables do not have versions. In fact, advertising a cable as an "HDMI 1.4 cable" or "HDMI 2.0 cable" or "HDMI 2.0 compliant" (etc.) has been banned by the HDMI Licensing authority since 2009, and any cable product which references HDMI version numbers is considered a non-compliant cable.
-
- So does that mean all HDMI cables are the same?- -
-
- What are the rules for referencing HDMI® version numbers? - - Effective January 1, 2012 [for non-cable products; this policy was effective immediately (2009) for HDMI cables], when marketing an HDMI Product, any references to HDMI version numbers is prohibited. - - HDMI Cables - - Using HDMI version numbers in the labeling, packaging, or promotion of any cable product is prohibited. This includes releases of the HDMI Specification (for example, HDMI 1.4, 1.3, etc.), interim version numbers (for example, HDMI 1.4a, 1.3a, etc.) and CTS (Compliance Test Specification) version numbers (for example, 1.4a, 1.3c, etc.). - - Cable products that refer to version numbers are considered non-compliant and subject to trademark enforcement actions. - - http://www.hdmi.org/learningcenter/trademark_logo_pub.aspx - http://www.hdmi.org/learningcenter/videos_player.aspx?v=trademark_cables - - - -
- No. There are several different types (or "categories") of HDMI cables, rated by bandwidth. This is not the same as an "HDMI version". The HDMI cable category certifies that the cable can handle a certain amount of bandwidth. Higher resolutions and higher refresh rates increase the bandwidth required for video transmission, so for high-bandwidth formats like 4K 60 Hz not all HDMI cables will function properly. All other features* of all HDMI versions do not depend on the cable to "support it". Features like HDR, audio, ARC, 3D, variable refresh, and anything else will work on any cable. HDMI 2.0 features do not require a so-called "HDMI 2.0 cable" rated for 18 Gbit/s, which is why they are not called "HDMI 2.0 cables" in the first place, they are called Premium High Speed HDMI cables (as listed in the table below). The only thing that requires these cables is high-bandwidth video like 4K 60 Hz. The cable does not affect support for any other feature of any HDMI version. (*The only exception to this is inline Ethernet, which does require a special "HDMI with Ethernet" cable.)
-
- High Speed HDMI Cables and HDMI 2.0- -
-
- - Because HDMI version 1.4 allows a maximum bandwidth of 10.2 Gbit/s and High Speed HDMI cables are certified to handle 10.2 Gbit/s, it seems natural to call them "HDMI 1.4 cables". Likewise, HDMI 2.0 allows up to 18.0 Gbit/s and Premium High Speed HDMI cables are certified for that speed, so it seems natural to call those cables "HDMI 2.0 cables". However, this should be avoided. Even if an HDMI cable can only handle 10.2 Gbit/s, using it with an HDMI 2.0 system will not "downgrade the connection to HDMI 1.4". It will limit the bandwidth (the maximum resolution and refresh rate) to 10.2 Gbit/s, but all other HDMI 2.0 features will not be affected and will work just fine. Cables do not affect feature/version support or compatibility, they only affect maximum bandwidth, which is why they are classified by bandwidth ratings and not by their "HDMI version", which is a property that cables do not actually have. - - It should also be noted that a certification is not a maximum bandwidth rating. If a cable carries a "High Speed" certification, it simply means that the cable was tested at 340 MHz (10.2 Gbit/s) and functioned properly at that speed. It may or may not continue to function properly at higher speeds, the certification doesn't test that. If you ask whether a regular High Speed (10.2 Gbit/s) HDMI cable will handle 18 Gbit/s speeds, the response is often "It won't be able to, High Speed cables can only handle up to 10.2 Gbit/s". No; High Speed cables can handle at least 10.2 Gbit/s. The bandwidth requirement of the certification is the minimum guaranteed, not the maximum it can handle. In fact quite a lot of normal High Speed HDMI cables can handle 4K 60 Hz perfectly well, but there's no way to tell whether it can or can't from the product description. Customer reviews can be enlightening in this situation. Just be wary of retailers like Amazon, which combine reviews from cables with multiple length options. Just because a 6 foot High Speed cable works at 4K 60 Hz doesn't mean the 10 foot variant of the same cable will also work at 4K 60 Hz. Length is the main factor in signal distortion in twisted-pair cable, so a longer version of a cable may not handle as much bandwidth as its shorter versions, even if they're all cut from the exact same cable stock. - - Of course, one might think "Well, if a cable were capable of handling 18 Gbit/s, it would have a Premium High Speed certification, not a High Speed certification". But actually, it wouldn't if it was certified during the first few years after HDMI 2.0 was released, when the Premium High Speed certification didn't exist. Every cable made during that time that functioned properly at 10.2 Gbit/s was given a High Speed certification, and that was that. Some of them could also handle 18 Gbit/s while others couldn't, but the High Speed certification doesn't discriminate between the two. - - -
-
-
-
- TLDR: - The vast majority of normal High Speed HDMI cables will work at 4K 60 Hz, they don't need to be special "4K" HDMI cables. If you're buying a new 4K display and already have some HDMI cables laying around, try them first. If it turns out they can't handle 4K 60 Hz (it's not absolutely guaranteed) then go look for a Premium High Speed certified HDMI cable, but in most cases you will not need any new cables. - - For existing High Speed cables with long lengths (10+ meters), it is less likely that they will be able to handle 4K 60 Hz. A Premium High Speed certified cable will probably be required. - - - Due to the way HDMI 2.0 was released (without an 18 Gbit/s certification for cables), there is some ambiguity as to whether or not High Speed HDMI cables (certified at 10.2 Gbit/s) will work at 18.0 Gbit/s. There is testimony for both sides; some people report that they tried several High Speed cables which failed at 18 Gbit/s speeds, and finally bought a cable advertising 18 Gbit/s (or "HDMI 2.0") which did work, and therefore insist that cables rated for HDMI 1.4 speeds are insufficient, and "HDMI 2.0 cables" are a real thing. And yet others report that they bought an "HDMI 1.4" cable rated for 10.2 Gbit/s, which worked perfectly at HDMI 2.0 speeds, and therefore insist that there are no special cables needed for HDMI 2.0, and that any normal High Speed HDMI cable will work fine at HDMI 2.0 speeds. - - The latter position can be hard to argue with, given that the HDMI Consortium gave this official statement when HDMI 2.0 was released: -
- Can existing HDMI cables support the higher bandwidths of HDMI 2.0 Specification? - - Yes, existing High Speed HDMI Cables (wire only) will support the new higher bandwidths (up to 18Gbps). - - - Numerous accounts of people using regular 10.2 Gbit/s-advertised High Speed HDMI cables for 4K 60 Hz add further support to this and make it a very solid position indeed. Unfortunately, it is not always true. Not all High Speed cables can handle 18 Gbit/s. Granted, most of them can, which is why many people have successfully used High Speed HDMI cables at 18 Gbit/s, but not all of them can, which is why others have experienced failures. - - Since signal integrity gets more and more difficult to control as the cable gets longer, it's mostly only with long cables that you start seeing High Speed certified cables that can't deliver 18 Gbit/s. Most of the time people deal with cables on the shorter side, maybe 2 to 3 meters long, where handling 18 Gbit/s is not much more difficult than 10.2 Gbit/s, so almost any cable capable of 10.2 Gbit/s can also be used for 18 Gbit/s at those lengths unless it really just barely passed the High Speed certification. - - However, at longer distances like 10 or 15 meters, manufacturing tolerances need to be a lot tighter to minimize distortion, and it's far less likely that a High Speed certified cable will continue to operate flawlessly all the way up to 18 Gbit/s. But, since most consumers only deal with shorter lengths where most High Speed cables do indeed work at HDMI 2.0 speeds, the failures at longer lengths went mostly unnoticed, and there have been countless articles written and shared across the internet about how all HDMI cables are the same and that any High Speed cable will work for HDMI 2.0 speeds, when in fact that isn't quite true in all situations. - - The HDMI Consortium has since created the Premium High Speed certification, which actually tests cables at 18 Gbit/s, to address this problem. -
- HDMI Licensing acknowledges the issue of some "high speed" cable not quite being up to the task of actually handling the full 2.0 bandwidth, saying: - - "Although many current High Speed HDMI Cables in the market will perform as originally expected (and support 18Gbps), some unanticipated technical characteristics of some compliant High Speed HDMI Cables that affect performance at higher speeds have been found. These cables are compliant with the Category 2 HDMI Cable requirements and perform successfully at 10.2Gbps, but may fail at 18 Gbps." - - - Of course, some people dismiss the "Premium High Speed" certification as a marketing ploy (or even deny that the certification exists) and continue to insist that any High Speed cable will work at 18 Gbit/s and that Premium High Speed cables are exactly the same. While it's true that most of the time a High Speed cable will do the job, in which case using a Premium High Speed cable makes exactly zero difference, it's simply false to say that all High Speed cables will work at 18 Gbit/s, despite what the HDMI Consortium's HDMI 2.0 FAQ page says. And in those cases, having a Premium High Speed certification does matter. They aren't just the same thing as High Speed cables re-labeled for marketing. As said of course, usually you won't need a Premium certified cable, but in some circumstances you might. - - BJC sums it up quite nicely in a sentence: -
- There is, therefore, for most users no reason to rush out and buy new cables to handle HDMI 2.0. It's quite possible, for reasons we'll get to, that you may find that you need to do this, but it's by no means a foregone conclusion.
- - - In short, if you're buying a new 4K 60 Hz display and already have some HDMI cables laying around, try them first. The vast majority of normal High Speed HDMI cables will work at 4K 60 Hz, they don't need to be special "4K" HDMI cables. If it does turn out that they don't work, then go look for a Premium High Speed certified cable. - - I would recommend reading these articles for more detail: - http://www.bluejeanscable.com/articles/note-about-hdmi-2.htm - http://www.bluejeanscable.com/articles/premium-hdmi-cable.htm - - | ||||||||||||||||||||

› | -- Is HDMI Limited to 60 Hz? - | -[Link] | -
- Is HDMI Limited to 60 Hz? - -
- No, HDMI is not limited to 60 Hz. Only HDMI 1.0 and 1.1 were restricted to specific formats (which were all 60 Hz and under), but this restriction was removed in HDMI 1.2 in 2005, and HDMI has not had any hard limit on refresh frequency since then. 720p 120 Hz is in fact explicitly listed in HDMI 1.2 as a supported format, although at 1080p it was still limited to 60 Hz by bandwidth constraints. HDMI 1.3 in 2006 alleviated these bandwidth constraints, increasing it to surpass Dual-Link DVI, and display makers have been free to implement 1080p 144 Hz over HDMI ever since then.
-
- But I have an ASUS VG248QE / BenQ XL2411Z / Acer GN246HL and it's capped at 60 Hz over HDMI!- - -
- Yes; these and many other 1080p 144 Hz monitors are equipped with HDMI 1.4a inputs, yet are still limited to 60 Hz over HDMI. This is just an unfortunate limitation of those particular monitors, it is not a limitation of the HDMI standard. Other monitors, such as the ViewSonic XG2401, the Nixeus NX-VUE24A, and the Samsung C24FG70 are also 1080p 144 Hz monitors with HDMI 1.4a ports, and they do accept 1080p 120/144 Hz over HDMI. It's purely a matter of manufacturer's discretion whether they want to implement that capability or not. Sadly, many instead choose to implement HDMI 1.4a with reduced bandwidth, presumably for cost-saving reasons.
-
- But if a product doesn't support the full bandwidth of HDMI 1.4a, surely it can't be HDMI 1.4a-compliant!- - The long and short of it is, some displays support 1080p 120+ Hz over HDMI 1.4, and some don't. It just depends on the display, so you'll need to do some research on whatever product you're considering. - - -
- Unfortunately it still can. Support for the full bandwidth is not a requirement for a device or control chip to be HDMI 1.4a-compliant. Very few displays (certainly during the peak years of HDMI 1.3/1.4) have specs that can even use the full bandwidth, so it wouldn't make sense to require that all devices wishing to implement any HDMI 1.4 features must use a more expensive control chip capable of the full bandwidth, when virtually none of them have any use for it.
-
- Isn't the extra bandwidth in HDMI 1.3+ only used for 3D at 60 Hz per eye?- - -
- No. This is something that people often repeat for some reason, that although HDMI 1.4 has over twice as much bandwidth as 1080p 60 Hz requires, that extra bandwidth is apparently only allowed to be used for 3D frame packing. While it is true that 3D is one of the uses for the extra bandwidth, there is no restriction on using it for other purposes, such as standard video transmission at higher resolutions and refresh frequencies. This claim that the extra bandwidth is only allowed to be used for 3D is a bit of a head scratcher when you consider that the bandwidth increase has been there since HDMI 1.3, but the 3D format definitions (such as frame packing) weren't added until HDMI 1.4.
-
- Wasn't support for 1080p 120 Hz only added in HDMI 1.4b (and therefore not supported in 1.4a and earlier)?- - But if you do meet anyone who insists that the extra bandwidth really is only allowed to be used for 3D, please feel free to ask them which page or section of the HDMI Specification establishes this supposed restriction, I'd be interested to find out. I've never had an answer. - - -
- No. This claim comes from people reading it on Wikipedia but not checking the citation, which was just a youtube video of some random guy saying so. Speaking as someone who has read the actual HDMI 1.4/a/b Specification documents, this claim of 1080p 120 Hz support being introduced in HDMI 1.4b is completely false. Nothing noteworthy was introduced in HDMI 1.4b (see here).
-
- Citation Needed !!!- - 1080p 120 Hz has been explicitly listed in the HDMI Specification as a supported format since HDMI 1.4 (not just 1.4b), but even under HDMI 1.3 or 1.3a it can be implemented as a vendor-specific format which is a perfectly valid approach. Video formats do not require "support" from the HDMI Specification to work, because the word "support" does not mean what most people think it means in this case. - - When the HDMI Specification "adds support" for a certain format, it doesn't mean it in the conventional sense of "adding the capability" as if it wasn't previously possible. They mean it in a more literal sense of adding supporting material to help strengthen it, by defining standardized timings for the format to help with compatibility and ease of implementation instead of leaving it purely to the vendor's discretion. - - A more obvious example of this usage of the term "support" is ultrawide formats; HDMI 2.0 "added support" for the 21:9 ratio, even though ultrawide resolutions were available before HDMI 2.0 even existed and were working just fine over HDMI 1.4a. "Adding support" for 21:9 just meant the HDMI 2.0 spec added material to help establish standardized formats and timings, not that 21:9 formats weren't possible in previous versions, and indeed the majority of ultrawide monitors use HDMI 1.4a even though it "doesn't support" 21:9 ratio formats. - - -
- Indeed.
- - - Here's the first sentence of the video section of the HDMI 1.4a Specification: - -
- HDMI Specification Version 1.4a (2010), §6.1
- - - 6.1 Overview - - HDMI allows any video format timing to be transmitted and displayed. To maximize interoperability between products, common DTV formats have been defined. These video format timings define the pixel and line counts and timing, synchronization pulse positions and duration, and whether the format is interlaced or progressive. HDMI also allows vendor-specific formats to be used. - - - "Any video format timing". Am I just taking it out of context and applying it beyond its intended meaning? No. Here's the same section from HDMI 1.1: - -
- HDMI Specification Version 1.1 (2004), §6.1
- - - 6.1 Overview - - HDMI allows a wide variety of explicity defined video format timings to be transmitted and displayed. These video format timings define the pixel and line counts and timing, synchronization pulse positions and duration, and whether the format is interlaced or progressive. - - - In HDMI 1.0 and 1.1, only certain pre-defined formats were allowed (listed in §6.1–6.3; all of them are 60 Hz and under, so HDMI was indirectly limited to 60 Hz by that). In 2005 with the release of HDMI 1.2, that clause was specifically changed to say what it still says today, that any format is allowed. It's quite deliberate. - - HDMI 1.2 was designed to make HDMI more viable for the PC space, by allowing any arbitrary resolution and refresh rate (within the bandwidth limit), as opposed to the strict adherence to only standardized home theater formats required by HDMI 1.0 and 1.1. Although it does still have a list of pre-defined formats (to maximize interoperability between products, as it says), any format which is not explicitly defined in the HDMI Specification may still be implemented as a vendor-specific format. - - HDMI 1.2 also expanded the list of explicitly defined formats itself to include some >60 Hz formats like 720p 120 Hz, so the claim that it or later versions of HDMI impose a flat 60 Hz limit is pure nonsense. - -
- HDMI Specification Version 1.2 (2005), §6.3.2
- - - 6.3.2 Secondary Video Format Timings - -
- - However, the maximum bandwidth of HDMI 1.2 was the same as 1.0 and 1.1, so at 1080p it was still limited to 60 Hz due to bandwidth constraints. - - In 2006, HDMI 1.3 increased the maximum bandwidth by over double, enough for up to 144 Hz at 1080p. From this point onwards display manufacturers have been free to implement 1080p 120/144 Hz as a vendor-specific format. - - HDMI 1.4 added 1080p 120 Hz to the list of explicitly defined formats, so it is no longer even necessary for the manufacturer to have to define their own timings for the format: - -
- HDMI Specification Version 1.4 (2009), §6.3.2
- - - 6.3.2 Secondary Video Format Timings - -
- - As for 1080p 144 Hz, as before, manufacturers are still free to implement it as a vendor-specific format, and some have done so already. - - If a 1080p 120+ Hz display doesn't support 120+ Hz over HDMI, it's the fault of that display model, not a limitation of the HDMI standard. - |

+ I have seen some controversy over whether DisplayPort to HDMI passive adapters count as "passive" or not, because they have an integrated circuit inside, so I want to comment on this point.
+ + + Although DisplayPort sources support the direct output of TMDS-encoded HDMI signals, it sends them at DisplayPort's native voltage (3.3 V) with AC coupling instead of the DC-coupled 5 V used by HDMI and DVI. Passive DisplayPort to HDMI adapters have a conversion circuit inside them which converts the voltage of the signals from AC-coupled 3.3 V to DC-coupled 5 V, called a level shifter. This does not make it an "active adapter", because it is not decoding DisplayPort packets and converting the information contained into an equivalent data stream in the 3-channel TMDS format that HDMI uses. The initial signal received by the adapter is already in the 3-channel TMDS format used by HDMI, and the adapter has no effect on the digital values of the signals passing through it, and so does not "convert" or modify any information in the data stream. It is a simple voltage change for electrical compatibility between the two systems, and the circuit is powered by the integrated 3.3 V power line from the DisplayPort source. + + The only real impact this has (from an engineering standpoint) is that it places a hard limit on what speeds a particular adapter can support, which is why there are different "types" of DP to HDMI adapters which support different speeds. This is because the output of the level shifter circuit needs to be able to keep up with frequency of the input signal (i.e. it needs to be able to change between 0 V and 5 V fast enough that it can generate digital signals at the required frequency). As new versions of HDMI keep doubling the frequency of the previous version, the DisplayPort to HDMI adapters made for the previous version are not suitable for supporting the newer speeds, so a new adapter using upgraded circuits is required each time. + |

› | ++ Which Cable Type Should I Use? (DisplayPort vs. HDMI vs. DVI vs. VGA) + | +[Link] | +
+
+ Which Cable Type Should I Use?
+ + +
+ It's generally recommended to avoid using VGA for computer monitors when possible. While it does work fine for most situations, the image quality can be degraded depending on the quality of the cable, and it's relatively easy to damage the cable which often results in color channels dropping out and requiring you to wiggle the cable around, and eventually replace it. On the other hand, VGA can be useful in some situations for consoles, and for using computers/laptops on TVs, since it usually avoids the overscan problems seen with HDMI (where the desktop is cut off on the edges), as well as HDCP compatibility issues that consoles sometimes have.
+
+
+ Between DVI, HDMI, and DisplayPort:
+ +
+
+
+ So HDMI and DisplayPort don't have better image quality than DVI?
+ + +
+ That's correct. Between DVI, HDMI, and DisplayPort, there is no difference in image quality when the same image settings are used. The difference is that HDMI and DisplayPort support a wider range of possible settings, so they can be used for situations that DVI can't be used for, like 4K 60 Hz or 30 bit/px color depth. But these extra capabilities don't make them any better at doing the other things.
+
+
+ What about between HDMI and DisplayPort?+ + Basically it works like this; DVI can do some stuff. HDMI and DisplayPort can do all the stuff that DVI can do, plus some more. But the stuff that they have in common with DVI, they don't do any better than DVI does, it's just that they have extra capabilities beyond that. If you don't have a monitor that actually uses those extra capabilities, then there is no advantage to using DisplayPort or HDMI compared to DVI. + + + At the moment, the vast majority of displays still fall within the capabilities of DVI, so HDMI and DisplayPort are only necessary if you want the extra features like inline audio, or for higher-end display formats like 2560×1440 at 144 Hz, or 4K. + + + +
+ It's pretty much the same as between DVI and HDMI / DP, just between the different versions of HDMI and DisplayPort instead. There is no difference in image quality between HDMI and DisplayPort. They both produce identical images when the same image settings are used. The choice between HDMI and DisplayPort only matters if one of them (usually HDMI) doesn't support the full specs of your monitor. For example, some 4K displays only have HDMI 1.4 and DisplayPort 1.2. Since HDMI 1.4 can't do 4K 60 Hz, but DisplayPort 1.2 can, you should use DisplayPort. However, if the monitor has an HDMI version which does support 4K 60 Hz (like HDMI 2.0), then it doesn't matter whether you use HDMI or DisplayPort.

+
+ Index:
+
+
+
+
+ + Which connections can support 120+ Hz? + +
+
+ In order of preference:
+
+
+ Which one should I use?+ + (Note that the source device and the display must BOTH support the required HDMI / DisplayPort version. Connections will be limited to the lower version between the two. HDMI and DisplayPort cables themselves do not have "versions", though may have bandwidth limitations. See here for more details on HDMI and DisplayPort cable selection: HDMI DisplayPort) + + At 1920×1080 (2K): +
+
+
+ + +
+ A straight DisplayPort connection is the preferred option in all cases. + + At 1920×1080 if DisplayPort is not available, then use Dual-Link DVI. If Dual-Link DVI is not available, you can try HDMI as a last resort, but it is not guaranteed to work for 120+ Hz (it depends on the monitor; some work, some don't). HDMI 1.3 and above are capable of 1080p 120+ Hz, but not all monitors implement this capability, some are limited to 60 Hz over HDMI. + + At 2560×1440 if DisplayPort is not available, then HDMI can be used if the monitor and source both support HDMI 2.0 or above. If the monitor and source do not both support HDMI 2.0 or above, then it will not be possible to use HDMI for 120+ Hz at 2560×1440. In this case, it may be possible to use Dual-Link DVI by setting a custom resolution, but it depends on monitor support and is not guaranteed to work. + + At 3840×2160 without compression, DisplayPort 1.3 or 1.4 can be used up to 120 Hz. Frequencies higher than these limits (such as 4K 144 Hz) will require Display Stream Compression (DSC), only supported by DisplayPort 1.4 or higher. + + + Isn’t HDMI limited to 60 Hz? + +
+ No, HDMI is not limited to 60 Hz. This is a common myth. Many 1080p 120+ Hz displays are capped at 60 Hz over HDMI, but this is a limitation of those particular displays, not a limitation of the HDMI standard. HDMI itself allows unlimited refresh frequencies, and this has been the case since version 1.2 in 2005. Please refer to the main article here.
+
+ Can I use a DisplayPort to Dual-Link DVI passive adapter / cable?+ + Conspicuous examples of such displays include the ASUS VG248QE, the BenQ XL2411Z, and the Acer GN246HL. All of these are 1080p 144 Hz monitors with HDMI 1.4a ports, but do not support more than 60 Hz over HDMI. However, other monitors like the ViewSonic XG2401, Nixeus NX-VUE24A, and Samsung C24FG70 do accept 1080p 120+ Hz through HDMI 1.4a. + + The refresh frequency limits of HDMI at some common resolutions are listed in the table here. HDMI 1.3 and above are capable of 144 Hz at 1080p, and HDMI 2.0 is capable of 144 Hz at 1440p. + + +
+ No. DisplayPort to Dual-Link DVI passive adapters / cables do not actually exist. Even though most DisplayPort to DVI adapters you see for sale are labeled as "Dual-Link", all of these are fake, they are only Single-Link DVI adapters in disguise.
+
+ Can I use an HDMI to Dual-Link DVI passive adapter / cable?+ + The DisplayPort connector has 20 pins, which means it can be used as a Single-Link DVI-D port via a passive adapter. However, Dual-Link DVI requires 25 pins, so a DisplayPort connector does not have enough pins to emulate a Dual-Link DVI connection. The additional DVI pins on "DisplayPort to Dual-Link DVI" adapters are not connected to anything at all, they are just for show, for marketing purposes. It is nothing but a Single-Link DVI-D adapter dressed up to appear like a Dual-Link DVI-D adapter. + + +
+ No, for the same reason as in the above section. HDMI to Dual-Link DVI passive adapters/cables do not exist. HDMI only has 19 pins, like Single-Link DVI-D. Even though most HDMI to DVI adapters you see for sale are "Dual-Link", all of these are fake, they are only Single-Link DVI adapters in disguise.
+
+ I have a BenQ XL2411Z / ASUS VG248QE / Acer GN246HL or another 120+ Hz monitor with no DisplayPort input. What should I do?+ + These HDMI to Single-Link DVI passive adapters may work for 120+ Hz if used from a DVI output (computer/source) to an HDMI input (display) because it acts as an HDMI connection when used in this configuration, and HDMI 1.3+ can support 1080p 120 Hz as mentioned previously, but this does require the monitor to accept 120+ Hz over HDMI, so it will not work on monitors like the BenQ XL2411Z or ASUS VG248QE, which are limited to 60 Hz on their HDMI ports. + + +
+ Connecting to the display's HDMI input
+ + + HDMI 1.3 and 1.4 can support up to 144 Hz at 1080p, but this will not work on all monitors. Some monitors such as the BenQ-Zowie XL2411(Z), the ASUS VG248QE, and the Acer GN246HL will not accept >60 Hz over HDMI even though they have HDMI 1.4a inputs. This is not because "HDMI is limited to 60 Hz" (it isn't), this is just a limitation of these particular products. + + On monitors that do accept >60 Hz over HDMI (such as the ViewSonic XG2401), you can use either a straight HDMI connection, a DVI to HDMI adapter, or a DisplayPort to HDMI Type 2 passive adapter (up to 120 Hz at 1080p). A DisplayPort to HDMI Type 1 passive adapter will be limited to HDMI 1.2 speeds (60 Hz at 1080p). + + Connecting to the display's DVI input + Single-Link DVI only supports up to 60 Hz at 1080p, so Dual-Link DVI is required for 120+ Hz. This means inexpensive DisplayPort-to-DVI or HDMI-to-DVI passive adapters / cables cannot be used, because DisplayPort and HDMI only support passive adapters to Single-Link DVI, not to Dual-Link. Almost all DisplayPort-to-DVI and HDMI-to-DVI cables / adapters have fake "Dual-Link" connectors on them, but don't be fooled; they are still Single-Link DVI adapters in disguise. DisplayPort and HDMI do not support passive adapters to Dual-Link DVI; it is physically impossible to create such an adapter due to an insufficient number of pins on the DP and HDMI connectors. + + If you are using a monitor that only has DVI and HDMI inputs (no DisplayPort) and also doesn't accept >60 Hz over HDMI (like the BenQ XL2411Z), then you must use the Dual-Link DVI input.

There are plenty of DisplayPort to Single-Link DVI active adapters, intended for multi-monitor configurations on some older AMD graphics cards (detailed here). Inexpensive DisplayPort to DVI active adapters are all Single-Link-only and will not work for 1080p 120+ Hz. True DP to DL-DVI active adapters are very expensive, and generally quite unreliable.

+
+ + What's the difference between a passive adapter and an active adapter? (Preface) + +
+ There are a lot of myths and confusion surrounding passive and active adapters, and there seems to be very little understanding of exactly what they are, how they both work, and how to identify them. Hopefully this article will help clear things up.
+
+ Passive Adapters+ + First, to make some general points clear since there is a lot of misinformation spread around: + Passive Adapters: +
+ + From a technical standpoint, the difference between an active adapter and a passive adapter is in the basic principle of operation. Being able to tell the difference between a passive and active adapter isn't as simple as looking for external features like power cables, bulkiness, or cost. Some active adapters require power cables, but less complex ones can get enough power directly from the port. Some active adapters, like DisplayPort to VGA, can be very inexpensive, compact, reliable, and require no power cables, and for this reason they are often mistaken or mislabeled as "passive adapters". However, these external features are not the criteria which actually define whether an adapter is passive or active. + + + So what is the difference exactly? Well... + + + There are many different signaling formats, or methods of representing and transmitting the information that makes up a video signal. Each different interface (VGA, HDMI, DisplayPort, etc.) uses a different format; they represent the information in different ways. If you (as a system designer) want your device to be able to communicate information to another device which uses a different format, there are two ways for this to happen. You can design your device to be able to communicate using the other device's format (make it "multi-lingual" in a sense), or you can insert a third-party device between them to convert the information from one format to the other en route (a "translator" if you will). A passive adapter works via the first approach, and an active adapters works via the second approach. + + + + +
+ A passive adapter works via the first approach described in the preface. As it turns out, the ports on your graphics card or laptop or other source device can output signals in multiple different formats. For example, DisplayPort ports are not just limited to sending DisplayPort signals; they can send signals in the HDMI or DVI formats if required. Of course, the only problem is that the DisplayPort port cannot physically morph itself into an HDMI port to allow you to plug in HDMI cables, so this is why the "passive adapter" is needed; the adapter does not do anything at all to the format of the electrical signal, it is just there to change the shape of the port to allow you to plug the correct cable in. When you use a DisplayPort to HDMI passive adapter, the adapter is not "converting" DisplayPort signals into HDMI signals. The electrical signals coming from the DP port are already in the HDMI format, the adapter is just changing the physical shape of the port.
+
+
+ + + Since passive adapters don't actually do anything themselves, they will only work for some very specific combinations of ports which have been pre-designed with the ability to communicate in other formats. The table below shows which connections are possible using passive adapters: + +
+
+ +
+ This table is an exhaustive list of all possible connections that can be made using passive adapters between DP, HDMI, DVI, and VGA. If it is not listed above, it is not possible with a passive adapter.
+
+ Passive adapter compatibility has nothing to do with analog and digital+ + While output ports can send multiple types of signals, most input ports will only accept signals in their native format. For example, if your display has a DVI-D input, it will only accept DVI signals. This means that you can connect to it from a DisplayPort, HDMI, or DVI output port, because all three of those ports know how to send the DVI signals that the input port requires. + + On the other hand, if your monitor has a DisplayPort input, you can only connect to it from a DisplayPort source. Neither DVI nor HDMI output ports know how to send DisplayPort signals, so they cannot communicate with just a passive adapter. In this case, an active adapter would be required to convert one of the other signals into the DisplayPort format, since DVI and HDMI ports cannot output DisplayPort signals themselves. + + The only type of input port that will accept more than one format is DVI-I, which can accept both DVI and VGA signals. However, it is very rare for a display to have a DVI-I input. Almost all DVI ports found on displays are DVI-D. + + +
+ Something important to notice about the table above is that the compatibility between formats has no relation to whether each format is analog or digital.
+
+ Passive adapter compatibility has nothing to do with bandwidth+ + DisplayPort outputs are capable of sending DVI and HDMI signals, so a passive adapter can be used to connect a DisplayPort output to a DVI or HDMI input. However, DVI and HDMI outputs are not capable of sending DisplayPort signals, so a passive adapter cannot be used to connect a DVI or HDMI output to a DisplayPort input. Just because "they're both digital" doesn't mean passive adapters can be used. + + DVI-I outputs are capable of sending VGA signals, so a passive adapter can be used to connect a DVI-I output to a VGA input. Just because "one's a digital standard and one's an analog standard" doesn't mean passive adapters can't be used. If your digital standard includes the ability to send analog signals when requested, then it's possible to use passive adapters to an analog standard, and that's all there is to it. + + People imagine that when one signal is digital and the other is analog, this makes it impossible change one to the other without some processing involved, making passive conversion impossible. Meanwhile if they are both digital, they are more closely related and this makes conversion very simple (insert hand-waving here). + + This talk about how easy or difficult it is to convert one signal to another is irrelevant here. Converting one signal to another is what an active adapter does. Passive adapters do not convert any signals. Yes, it is impossible to convert an analog format into a digital format without any processing. That's because it's impossible to convert ANY format to ANY OTHER format without processing. There is no such thing as "passively converting" a signal. It doesn't matter whether it is analog to digital or digital to digital; ANY kind of signal conversion is impossible without an active adapter, period. + + Passive adapters work because source ports can output video in multiple different formats, so no conversion is necessary. These formats do not have to be related in any way. If you want to know whether or not you can use a passive adapter for a certain format, the answer has nothing to do with the port's other formats. + + For example, if you want to know whether or not DVI ports can support passive adapters to VGA, DVI being a digital format doesn't have anything to do with VGA adapter support, because the DVI format isn't being used when you're using a passive adapter. The correct question is, "are DVI ports capable of sending VGA signals instead of DVI signals?", and the answer is "yes, if it's a DVI-I port". Thus, passive DVI to VGA adapters are possible, despite the DVI format itself being digital. + + Likewise, if you want to know whether DisplayPort to VGA passive adapters exist or not, asking "is the DisplayPort format digital or analog" is completely irrelevant, because there aren't any DisplayPort signals involved when a passive adapters is used. The question is "are DisplayPort ports capable of sending VGA signals instead of DisplayPort signals?", and the answer is "no", so DisplayPort to VGA signals are therefore not possible. It has nothing to do with the DisplayPort format being digital, DisplayPort simply wasn't designed with the ability to alternatively send VGA signals, while DVI was. + + There are no rules of thumb, like "digital to digital is possible passively, analog to digital isn't". The compatibility of passive adapters is completely arbitrary and just comes down to what capabilities each video standard was designed with. + + +
+ Another surprise to most people is that DisplayPort 1.2 doesn't support passive adapters to HDMI 2.0, or that DisplayPort and HDMI don't support passive adapters to Dual-Link DVI, only to Single-Link DVI. Upon being informed of this, the response is usually something along the lines of "well that doesn't make any sense; they're both digital, and the bandwidth of DisplayPort is greater than Dual-Link DVI / HDMI 2.0, etc. so a passive adapter should work!" But again, this is based on a misunderstanding of how passive adapters work.
+
+ Passive adapters are not necessarily limited to the lowest common denominator+ + People imagine that a passive DP to DVI adapter is "converting" DisplayPort signals into DVI signals, as if the image is originally sent as a DisplayPort signal and an adapter transforms it into an equivalent Dual-Link DVI signal, which should work because any Dual-Link DVI data stream will "fit" inside a DisplayPort signal since the bandwidth of DisplayPort is greater than that of DL-DVI. This is all very sensible sounding, and is a wonderful description of how an active adapter works, not a passive adapter. + + A passive adapter does not "convert" a signal from format to another. The original signal is sent in the desired format to begin with, and the adapter is just changing the physical shape of the port so that the correct cables can be plugged in. In a DisplayPort to DVI (or HDMI to DVI) passive adapter, the DisplayPort output port is essentially used as a DVI port; all of the pins are used to send the same electrical signals that a DVI port's pins would (more or less). Of course, the DisplayPort port is still shaped like a DisplayPort port and so DVI cables will not fit—that's what the passive adapter is needed for—but electrically it is acting as a DVI port. But a DisplayPort port also only has 20 pins (compared to 19 pins on SL-DVI-D and 25 pins on DL-DVI-D), so it can only send signals that a Single-Link DVI port would send; it is physically impossible for it to send Dual-Link DVI signals in this manner, because it simply doesn't have enough pins to send the same signals that a DL-DVI port would. HDMI ports (which have 19 pins) are also subject to the same restriction; they can only send Single-Link DVI signals, not Dual-Link. + + And again a similar concept applies to DisplayPort to HDMI adapters; many people are perplexed when they discover that DisplayPort 1.2 only supports adapters up to HDMI 1.4. "But DP 1.2 has more bandwidth than HDMI 2.0!" Yes it does—but since adapters don't work by "converting" DisplayPort signals into equivalent HDMI signals, it doesn't matter if HDMI 2.0 signals "fit" inside a DisplayPort 1.2 signal. The bandwidth of DisplayPort is irrelevant, because there are no DisplayPort signals involved at all. DisplayPort 1.2 only supports adapters to HDMI 1.4 because the DisplayPort control chips are not designed to send HDMI signals greater than that (mostly because DisplayPort 1.2 was published in 2009 and HDMI 2.0 didn't exist until around 2013 or so). DisplayPort 1.3 (2014) does support passive adapters to HDMI 2.0. + + +
+ Another bit of seemingly sensible wisdom which turns out to be not always true is that when using a passive adapter, you'll be limited to lowest capabilities of the two interfaces involved. For example, if using a DVI to HDMI adapter, many people will tell you that audio won't work. After all, DVI signals contain no audio, and converting an audio-free signal to the HDMI format won't make audio magically appear. But again, this is based on the idea that an adapter "converts" DVI signals into HDMI signals, so this is information that applies to active adapters, not passive adapters. When using a passive adapter from a DVI source to an HDMI display, the output device detects an HDMI display and sends HDMI signals to it, including audio. Whether DVI signals contain audio or not is irrelevant, because there are no DVI signals involved. The adapter isn't "converting" DVI signals into HDMI signals, the signals are sent in the HDMI format to begin with.
+
+ Do passive adapters add any latency?+ + While it is sometimes true that you'll be limited to the lowest capabilities between the two interfaces, it isn't always true. Check the specific adapter combination you are wondering about using the dropdown interface at the top of this guide. + + + No.
+
+ Do passive adapters reduce image quality?+ + No.
+
+ Active Adapters+ +
+ Active adapters (or "signal converters") use the second approach described in the preface; both the source device and the display send/receive signals in their native formats, but there is a device in the middle (the adapter) which converts the information from one format to the other. Active adapters are required for any combination of ports that isn't possible with passive adapters (as listed above). Active adapters have also been used in some situations historically to circumenvent limitations of passive adapters; for example, some older AMD graphics cards could support up to 6 monitors, but only maximum of two could be using DVI/HDMI signals (including sending DVI/HDMI signals through a DisplayPort port via a passive adapter); the rest had to use native DisplayPort output. DisplayPort to DVI/HDMI active adapters were useful in this case to allow additional DVI/HDMI connections, since the graphics card would send native DisplayPort signals, which were then intercepted by the adapter and converted to the DVI/HDMI format en route.
+
+
+ Do active adapters add any latency?+ + Active adapters have a processor which converts between the two formats, so they are more expensive than passive adapters and may require a power cable, depending on the complexity of the conversion. Since active adapters convert information from one format into its equivalent in a different format, they are limited only to the features and capabilities supported by both formats. This means active adapters won't support anything that isn't supported by both sides of the connection, including limitations on maximum bandwidth, audio support, and any other features such as G-Sync or daisy-chaining. In addition, certain active adapters may have their own limitations depending on what the signal processor can handle. For example, many (but not all) HDMI to DisplayPort active adapters are limited to 1920×1200 at 60 Hz. Even though both connections can go beyond that, the processor used inside those adapters can’t process data quickly enough to do more than that. For 1440p or 4K resolutions, even more expensive adapters with more powerful processors must be used. + + + Active adapters usually only work in one direction. An active adapter that receives a VGA signal and converts it into HDMI usually isn’t equipped to receive HDMI signals and turn them into VGA instead. When purchasing an active adapter, read the product description carefully. + + + In theory, any signal can be converted to any other signal with an active adapter, although in practice there is not an adapter manufactured for every conceivable combination of ports. + + + +
+ Depends on the adapter, but usually they do not add any meaningful amount of latency.
+
+
+ Do active adapters reduce image quality?+ + +
+ No. But when converting between two different formats the image quality will only be as good as the worse format.
+
+
+ How can I tell if an adapter is passive or active?+ + +
+ Some people think that "active adapter" means it has an additional plug for power, but this is not the case. If an adapter needs a power cable, it is definitely an active adapter, but if it doesn't need a power cable, it could still be either an active or a passive adapter. It is not possible to tell the difference between them by looking at them, because "active" and "passive" aren't defined by any external feature, as explained above. Some active adapters may have conversion circuitry so small that it can be powered from the port and embedded in the cable termination, so that it appears just like any normal passive adapter cable.
+
+
+ Which type should I use?+ + Sometimes it isn't possible to tell whether an adapter is active or passive, but there are some steps you can take to rule out one or the other. Only specific combinations of ports are possible with passive adapters, listed in the table a few paragraphs above. If the adapter you are looking at isn't a type listed on that table, it must be an active adapter (or fake). If it is a combination listed on that table, then it could be either passive or active. Usually the product description will tell you, but if it doesn't, you should generally assume it is passive, because companies don't normally make active adapters for port combinations that can already be done using passive adapters. + + + However, there are some exceptions to this. Even though DisplayPort supports passive adapters to HDMI and Single-Link DVI, there are many active adapters also available for these combinations due to restrictions on multi-monitor configurations on some older AMD graphics cards (see here). So DisplayPort to DVI adapters or DisplayPort to HDMI adapters may either be passive or active; reading the product description will usually tell you. + + + In addition sometimes active adapters may be required between DisplayPort and HDMI depending on which versions you want; for example, DisplayPort 1.2 does support passive adapters to HDMI, but only up to HDMI 1.4; to get a full HDMI 2.0 connection from DisplayPort 1.2, you need an active adapter. + + + More specific information on what combinations are supported with passive adapters can be found by entering a specific combination of ports in the dropdown menus at the top of this guide. + + + +
+ If a passive adapter is possible for the configuration you want (check using the utility at the top of this guide), then usually you should use the passive adapter. Active adapters tend to be more expensive and less reliable, and only exist for situations where passive adapters won't work.

› | ++ Active Adapter Requirements for Multi-Monitor Configurations + | +[Link] | +
+
+ Certain older AMD graphics cards require a native DisplayPort connection or DisplayPort active adapters to connect more than 2 monitors. DisplayPort to Single-Link DVI active adapters are useful in this situation to avoid the cost of an active Dual-Link adapter. This limitation ONLY applies to certain older AMD graphics cards. NVIDIA graphics cards have never had this limitation, and newer AMD graphics cards also no longer have it, so these cards DO NOT require DisplayPort or active DisplayPort adapters for any multi-monitor configurations.
+ + + Graphics cards with this limitation can still support 3+ monitors, but only a maximum of two may be connected through any combination of the following: +

› | ++ Do HDMI Cables Have Versions? + | +[Link] | +||||||||||||||||||
+
+ Do HDMI cables have versions?
+ + +
+ No, HDMI cables do not have versions. In fact, advertising a cable as an "HDMI 1.4 cable" or "HDMI 2.0 cable" or "HDMI 2.0 compliant" (etc.) has been banned by the HDMI Licensing authority since 2009, and any cable product which references HDMI version numbers is considered a non-compliant cable.
+
+ So does that mean all HDMI cables are the same?+ +
+
+ What are the rules for referencing HDMI® version numbers? + + Effective January 1, 2012 [for non-cable products; this policy was effective immediately (2009) for HDMI cables], when marketing an HDMI Product, any references to HDMI version numbers is prohibited. + + HDMI Cables + + Using HDMI version numbers in the labeling, packaging, or promotion of any cable product is prohibited. This includes releases of the HDMI Specification (for example, HDMI 1.4, 1.3, etc.), interim version numbers (for example, HDMI 1.4a, 1.3a, etc.) and CTS (Compliance Test Specification) version numbers (for example, 1.4a, 1.3c, etc.). + + Cable products that refer to version numbers are considered non-compliant and subject to trademark enforcement actions. + + http://www.hdmi.org/learningcenter/trademark_logo_pub.aspx + http://www.hdmi.org/learningcenter/videos_player.aspx?v=trademark_cables + + + +
+ No. There are several different types (or "categories") of HDMI cables, rated by bandwidth. This is not the same as an "HDMI version". The HDMI cable category certifies that the cable can handle a certain amount of bandwidth. Higher resolutions and higher refresh rates increase the bandwidth required for video transmission, so for high-bandwidth formats like 4K 60 Hz not all HDMI cables will function properly. All other features* of all HDMI versions do not depend on the cable to "support it". Features like HDR, audio, ARC, 3D, variable refresh, and anything else will work on any cable. HDMI 2.0 features do not require a so-called "HDMI 2.0 cable" rated for 18 Gbit/s, which is why they are not called "HDMI 2.0 cables" in the first place, they are called Premium High Speed HDMI cables (as listed in the table below). The only thing that requires these cables is high-bandwidth video like 4K 60 Hz. The cable does not affect support for any other feature of any HDMI version. (*The only exception to this is inline Ethernet, which does require a special "HDMI with Ethernet" cable.)
+
+ High Speed HDMI Cables and HDMI 2.0+ +
+
+ + Because HDMI version 1.4 allows a maximum bandwidth of 10.2 Gbit/s and High Speed HDMI cables are certified to handle 10.2 Gbit/s, it seems natural to call them "HDMI 1.4 cables". Likewise, HDMI 2.0 allows up to 18.0 Gbit/s and Premium High Speed HDMI cables are certified for that speed, so it seems natural to call those cables "HDMI 2.0 cables". However, this should be avoided. Even if an HDMI cable can only handle 10.2 Gbit/s, using it with an HDMI 2.0 system will not "downgrade the connection to HDMI 1.4". It will limit the bandwidth (the maximum resolution and refresh rate) to 10.2 Gbit/s, but all other HDMI 2.0 features will not be affected and will work just fine. Cables do not affect feature/version support or compatibility, they only affect maximum bandwidth, which is why they are classified by bandwidth ratings and not by their "HDMI version", which is a property that cables do not actually have. + + It should also be noted that a certification is not a maximum bandwidth rating. If a cable carries a "High Speed" certification, it simply means that the cable was tested at 340 MHz (10.2 Gbit/s) and functioned properly at that speed. It may or may not continue to function properly at higher speeds, the certification doesn't test that. If you ask whether a regular High Speed (10.2 Gbit/s) HDMI cable will handle 18 Gbit/s speeds, the response is often "It won't be able to, High Speed cables can only handle up to 10.2 Gbit/s". No; High Speed cables can handle at least 10.2 Gbit/s. The bandwidth requirement of the certification is the minimum guaranteed, not the maximum it can handle. In fact quite a lot of normal High Speed HDMI cables can handle 4K 60 Hz perfectly well, but there's no way to tell whether it can or can't from the product description. Customer reviews can be enlightening in this situation. Just be wary of retailers like Amazon, which combine reviews from cables with multiple length options. Just because a 6 foot High Speed cable works at 4K 60 Hz doesn't mean the 10 foot variant of the same cable will also work at 4K 60 Hz. Length is the main factor in signal distortion in twisted-pair cable, so a longer version of a cable may not handle as much bandwidth as its shorter versions, even if they're all cut from the exact same cable stock. + + Of course, one might think "Well, if a cable were capable of handling 18 Gbit/s, it would have a Premium High Speed certification, not a High Speed certification". But actually, it wouldn't if it was certified during the first few years after HDMI 2.0 was released, when the Premium High Speed certification didn't exist. Every cable made during that time that functioned properly at 10.2 Gbit/s was given a High Speed certification, and that was that. Some of them could also handle 18 Gbit/s while others couldn't, but the High Speed certification doesn't discriminate between the two. + + +
+
+
+
+ TLDR: + The vast majority of normal High Speed HDMI cables will work at 4K 60 Hz, they don't need to be special "4K" HDMI cables. If you're buying a new 4K display and already have some HDMI cables laying around, try them first. If it turns out they can't handle 4K 60 Hz (it's not absolutely guaranteed) then go look for a Premium High Speed certified HDMI cable, but in most cases you will not need any new cables. + + For existing High Speed cables with long lengths (10+ meters), it is less likely that they will be able to handle 4K 60 Hz. A Premium High Speed certified cable will probably be required. + + + Due to the way HDMI 2.0 was released (without an 18 Gbit/s certification for cables), there is some ambiguity as to whether or not High Speed HDMI cables (certified at 10.2 Gbit/s) will work at 18.0 Gbit/s. There is testimony for both sides; some people report that they tried several High Speed cables which failed at 18 Gbit/s speeds, and finally bought a cable advertising 18 Gbit/s (or "HDMI 2.0") which did work, and therefore insist that cables rated for HDMI 1.4 speeds are insufficient, and "HDMI 2.0 cables" are a real thing. And yet others report that they bought an "HDMI 1.4" cable rated for 10.2 Gbit/s, which worked perfectly at HDMI 2.0 speeds, and therefore insist that there are no special cables needed for HDMI 2.0, and that any normal High Speed HDMI cable will work fine at HDMI 2.0 speeds. + + The latter position can be hard to argue with, given that the HDMI Consortium gave this official statement when HDMI 2.0 was released: +
+ Can existing HDMI cables support the higher bandwidths of HDMI 2.0 Specification? + + Yes, existing High Speed HDMI Cables (wire only) will support the new higher bandwidths (up to 18Gbps). + + + Numerous accounts of people using regular 10.2 Gbit/s-advertised High Speed HDMI cables for 4K 60 Hz add further support to this and make it a very solid position indeed. Unfortunately, it is not always true. Not all High Speed cables can handle 18 Gbit/s. Granted, most of them can, which is why many people have successfully used High Speed HDMI cables at 18 Gbit/s, but not all of them can, which is why others have experienced failures. + + Since signal integrity gets more and more difficult to control as the cable gets longer, it's mostly only with long cables that you start seeing High Speed certified cables that can't deliver 18 Gbit/s. Most of the time people deal with cables on the shorter side, maybe 2 to 3 meters long, where handling 18 Gbit/s is not much more difficult than 10.2 Gbit/s, so almost any cable capable of 10.2 Gbit/s can also be used for 18 Gbit/s at those lengths unless it really just barely passed the High Speed certification. + + However, at longer distances like 10 or 15 meters, manufacturing tolerances need to be a lot tighter to minimize distortion, and it's far less likely that a High Speed certified cable will continue to operate flawlessly all the way up to 18 Gbit/s. But, since most consumers only deal with shorter lengths where most High Speed cables do indeed work at HDMI 2.0 speeds, the failures at longer lengths went mostly unnoticed, and there have been countless articles written and shared across the internet about how all HDMI cables are the same and that any High Speed cable will work for HDMI 2.0 speeds, when in fact that isn't quite true in all situations. + + The HDMI Consortium has since created the Premium High Speed certification, which actually tests cables at 18 Gbit/s, to address this problem. +
+ HDMI Licensing acknowledges the issue of some "high speed" cable not quite being up to the task of actually handling the full 2.0 bandwidth, saying: + + "Although many current High Speed HDMI Cables in the market will perform as originally expected (and support 18Gbps), some unanticipated technical characteristics of some compliant High Speed HDMI Cables that affect performance at higher speeds have been found. These cables are compliant with the Category 2 HDMI Cable requirements and perform successfully at 10.2Gbps, but may fail at 18 Gbps." + + + Of course, some people dismiss the "Premium High Speed" certification as a marketing ploy (or even deny that the certification exists) and continue to insist that any High Speed cable will work at 18 Gbit/s and that Premium High Speed cables are exactly the same. While it's true that most of the time a High Speed cable will do the job, in which case using a Premium High Speed cable makes exactly zero difference, it's simply false to say that all High Speed cables will work at 18 Gbit/s, despite what the HDMI Consortium's HDMI 2.0 FAQ page says. And in those cases, having a Premium High Speed certification does matter. They aren't just the same thing as High Speed cables re-labeled for marketing. As said of course, usually you won't need a Premium certified cable, but in some circumstances you might. + + BJC sums it up quite nicely in a sentence: +
+ There is, therefore, for most users no reason to rush out and buy new cables to handle HDMI 2.0. It's quite possible, for reasons we'll get to, that you may find that you need to do this, but it's by no means a foregone conclusion.
+ + + In short, if you're buying a new 4K 60 Hz display and already have some HDMI cables laying around, try them first. The vast majority of normal High Speed HDMI cables will work at 4K 60 Hz, they don't need to be special "4K" HDMI cables. If it does turn out that they don't work, then go look for a Premium High Speed certified cable. + + I would recommend reading these articles for more detail: + http://www.bluejeanscable.com/articles/note-about-hdmi-2.htm + http://www.bluejeanscable.com/articles/premium-hdmi-cable.htm + + | ||||||||||||||||||||

+ Is HDMI Limited to 60 Hz? + +
+ No, HDMI is not limited to 60 Hz. Only HDMI 1.0 and 1.1 were restricted to specific formats (which were all 60 Hz and under), but this restriction was removed in HDMI 1.2 in 2005, and HDMI has not had any hard limit on refresh frequency since then. 720p 120 Hz is in fact explicitly listed in HDMI 1.2 as a supported format, although at 1080p it was still limited to 60 Hz by bandwidth constraints. HDMI 1.3 in 2006 alleviated these bandwidth constraints, increasing it to surpass Dual-Link DVI, and display makers have been free to implement 1080p 144 Hz over HDMI ever since then.

+ But I have an ASUS VG248QE / BenQ XL2411Z / Acer GN246HL and it's capped at 60 Hz over HDMI!+ + +
+ Yes; these and many other 1080p 144 Hz monitors are equipped with HDMI 1.4a inputs, yet are still limited to 60 Hz over HDMI. This is just an unfortunate limitation of those particular monitors, it is not a limitation of the HDMI standard. Other monitors, such as the ViewSonic XG2401, the Nixeus NX-VUE24A, and the Samsung C24FG70 are also 1080p 144 Hz monitors with HDMI 1.4a ports, and they do accept 1080p 120/144 Hz over HDMI. It's purely a matter of manufacturer's discretion whether they want to implement that capability or not. Sadly, many instead choose to implement HDMI 1.4a with reduced bandwidth, presumably for cost-saving reasons.
+
+ But if a product doesn't support the full bandwidth of HDMI 1.4a, surely it can't be HDMI 1.4a-compliant!+ + The long and short of it is, some displays support 1080p 120+ Hz over HDMI 1.4, and some don't. It just depends on the display, so you'll need to do some research on whatever product you're considering. + + +
+ Unfortunately it still can. Support for the full bandwidth is not a requirement for a device or control chip to be HDMI 1.4a-compliant. Very few displays (certainly during the peak years of HDMI 1.3/1.4) have specs that can even use the full bandwidth, so it wouldn't make sense to require that all devices wishing to implement any HDMI 1.4 features must use a more expensive control chip capable of the full bandwidth, when virtually none of them have any use for it.
+
+ Isn't the extra bandwidth in HDMI 1.3+ only used for 3D at 60 Hz per eye?+ + +
+ No. This is something that people often repeat for some reason, that although HDMI 1.4 has over twice as much bandwidth as 1080p 60 Hz requires, that extra bandwidth is apparently only allowed to be used for 3D frame packing. While it is true that 3D is one of the uses for the extra bandwidth, there is no restriction on using it for other purposes, such as standard video transmission at higher resolutions and refresh frequencies. This claim that the extra bandwidth is only allowed to be used for 3D is a bit of a head scratcher when you consider that the bandwidth increase has been there since HDMI 1.3, but the 3D format definitions (such as frame packing) weren't added until HDMI 1.4.
+
+ Wasn't support for 1080p 120 Hz only added in HDMI 1.4b (and therefore not supported in 1.4a and earlier)?+ + But if you do meet anyone who insists that the extra bandwidth really is only allowed to be used for 3D, please feel free to ask them which page or section of the HDMI Specification establishes this supposed restriction, I'd be interested to find out. I've never had an answer. + + +
+ No. This claim comes from people reading it on Wikipedia but not checking the citation, which was just a youtube video of some random guy saying so. Speaking as someone who has read the actual HDMI 1.4/a/b Specification documents, this claim of 1080p 120 Hz support being introduced in HDMI 1.4b is completely false. Nothing noteworthy was introduced in HDMI 1.4b (see here).
+
+ Citation Needed !!!+ + 1080p 120 Hz has been explicitly listed in the HDMI Specification as a supported format since HDMI 1.4 (not just 1.4b), but even under HDMI 1.3 or 1.3a it can be implemented as a vendor-specific format which is a perfectly valid approach. Video formats do not require "support" from the HDMI Specification to work, because the word "support" does not mean what most people think it means in this case. + + When the HDMI Specification "adds support" for a certain format, it doesn't mean it in the conventional sense of "adding the capability" as if it wasn't previously possible. They mean it in a more literal sense of adding supporting material to help strengthen it, by defining standardized timings for the format to help with compatibility and ease of implementation instead of leaving it purely to the vendor's discretion. + + A more obvious example of this usage of the term "support" is ultrawide formats; HDMI 2.0 "added support" for the 21:9 ratio, even though ultrawide resolutions were available before HDMI 2.0 even existed and were working just fine over HDMI 1.4a. "Adding support" for 21:9 just meant the HDMI 2.0 spec added material to help establish standardized formats and timings, not that 21:9 formats weren't possible in previous versions, and indeed the majority of ultrawide monitors use HDMI 1.4a even though it "doesn't support" 21:9 ratio formats. + + +
+ Indeed.
+ + + Here's the first sentence of the video section of the HDMI 1.4a Specification: + +
+ HDMI Specification Version 1.4a (2010), §6.1
+ + + 6.1 Overview + + HDMI allows any video format timing to be transmitted and displayed. To maximize interoperability between products, common DTV formats have been defined. These video format timings define the pixel and line counts and timing, synchronization pulse positions and duration, and whether the format is interlaced or progressive. HDMI also allows vendor-specific formats to be used. + + + "Any video format timing". Am I just taking it out of context and applying it beyond its intended meaning? No. Here's the same section from HDMI 1.1: + +
+ HDMI Specification Version 1.1 (2004), §6.1
+ + + 6.1 Overview + + HDMI allows a wide variety of explicity defined video format timings to be transmitted and displayed. These video format timings define the pixel and line counts and timing, synchronization pulse positions and duration, and whether the format is interlaced or progressive. + + + In HDMI 1.0 and 1.1, only certain pre-defined formats were allowed (listed in §6.1–6.3; all of them are 60 Hz and under, so HDMI was indirectly limited to 60 Hz by that). In 2005 with the release of HDMI 1.2, that clause was specifically changed to say what it still says today, that any format is allowed. It's quite deliberate. + + HDMI 1.2 was designed to make HDMI more viable for the PC space, by allowing any arbitrary resolution and refresh rate (within the bandwidth limit), as opposed to the strict adherence to only standardized home theater formats required by HDMI 1.0 and 1.1. Although it does still have a list of pre-defined formats (to maximize interoperability between products, as it says), any format which is not explicitly defined in the HDMI Specification may still be implemented as a vendor-specific format. + + HDMI 1.2 also expanded the list of explicitly defined formats itself to include some >60 Hz formats like 720p 120 Hz, so the claim that it or later versions of HDMI impose a flat 60 Hz limit is pure nonsense. + +
+ HDMI Specification Version 1.2 (2005), §6.3.2
+ + + 6.3.2 Secondary Video Format Timings + +
+ + However, the maximum bandwidth of HDMI 1.2 was the same as 1.0 and 1.1, so at 1080p it was still limited to 60 Hz due to bandwidth constraints. + + In 2006, HDMI 1.3 increased the maximum bandwidth by over double, enough for up to 144 Hz at 1080p. From this point onwards display manufacturers have been free to implement 1080p 120/144 Hz as a vendor-specific format. + + HDMI 1.4 added 1080p 120 Hz to the list of explicitly defined formats, so it is no longer even necessary for the manufacturer to have to define their own timings for the format: + +
+ HDMI Specification Version 1.4 (2009), §6.3.2
+ + + 6.3.2 Secondary Video Format Timings + +
+ + As for 1080p 144 Hz, as before, manufacturers are still free to implement it as a vendor-specific format, and some have done so already. + + If a 1080p 120+ Hz display doesn't support 120+ Hz over HDMI, it's the fault of that display model, not a limitation of the HDMI standard. + |
