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.

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.

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.

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 patently false:

+ * "Type 3" is an unofficial name. These HDMI 2.0 passive adapters are defined in the DisplayPort 1.3 specification, but no adapters of this type have been produced yet, so it is not possible to obtain one at the moment. Until then, adapting to HDMI 2.0 must be done using an active adapter. +

+ Only the highest common / standard frequencies are listed (24 / 30 / 50 / 60 / 75 / 85 / 100 / 120 / 144 / 180 / 200 / 240 Hz, or higher multiples of 60). This table is not meant to list the absolute limits down to the very last Hz. For more exact limits, refer to the bandwidth calculator here. +
