I've read that for a lot of 120Hz, 144Hz and higher refresh rate, you have to use DisplayPort output from the GPU, and sometimes even 2 at the same time if the resolution is very high. But if I'm looking for a FullHD monitor with 144Hz refresh rate, can I use HDMI? Or does it depend on each monitor's model?

    HDMI 2.1 is fully capable of 4K 120 Hz refresh rates. You would have to look at the monitor’s specifications to determine if a given monitor supports it though. – Ramhound Jun 1 '18 at 20:40

It depends on the HDMI version. You'll need HDMI 1.3 or above for 1080p and 120 Hz or more.

EDIT: Your monitor and graphics card do still need to support a 120 or 144 Hz refresh rate at the resolution you desire. DisplayPort works too.

The Wikipedia article has a really useful table:

  • Both the monitor and the GPU have to match this spec, right? – user1306322 Jun 1 '18 at 21:07

HDMI supports 1080p 120hz, although it cannot use a 1080p 144hz mode. For that, a DisplayPort cable is required.
