[SOLVED] Can HDMI 2.0 run 144 Hz?

[solozrenn]

I want to buy a 144 Hz gaming monitor, to use as a display for my PC. The PC doesn't have a DVI port though, just an HDMI. So, I was wondering if an HDMI 2.0 can run at 144 Hz.

HDMI 1.3 and above are capable of 144 Hz at 1080p. HDMI is not capped at 60 Hz as some people will tell you, even in versions below 2.0.

However, the monitor must also support 144 Hz over HDMI, it is not enough just to have a laptop or graphics card with an HDMI 1.4 or 2.0 port. The display must support 144 Hz over HDMI, and the HDMI version alone will not tell you if the monitor supports it. Some monitors are limited to 60 Hz over HDMI even if they have HDMI 1.4 or HDMI 2.0 inputs. This is a limitation of those monitors, not a limitation of the HDMI standard.

Some monitors that support 1080p 144 Hz over HDMI are the ViewSonic XG2401 and the Nixeus NX-VUE24A. There are also monitors that support up to 120 Hz over HDMI but not 144 Hz, like the Samsung C24FG70. All of these monitors are listed as having HDMI 1.4.

Popular monitors that people will recommend such as the ASUS VG248QE and the BenQ XL2411Z, do not support 144 Hz over HDMI, and regardless I do not recommend these monitors anyway since they are quite old models and are not good value for the price.

If you want to run 1080p 144 Hz and you only have HDMI output, then I recommend the ViewSonic XG2401.

Donot forget, 1080p 144hz via HDMI will only work if both the monitor and PC have at least HDMI 1.3.
There are cases, some monitors can only do 144hz via DP or DVI-D dual link, since those monitors have only HDMI e.g. 1.2.

The reason for 1080p 144 Hz monitors being limited to 60 Hz is not from having HDMI 1.2, in almost every case these monitors have HDMI 1.4, they are simply limited to 60 Hz over HDMI anyway. It's just a limitation of those monitors, they do have HDMI 1.4, they just don't support the full bandwidth of it.
