HDMI’s more buff brother, looks like an HDMI
connector but with one side flat. It’s intended purpose is for computer monitors only(some TVs have them, but rare). Can support up to 16K resolution at 80Hz without HDR
and 60Hz with HDR, also supports Freesync
which reduces screen tearing.
Man I wished I bought a displayport cable for my computer, I guess I’ll stick to my hdmi cable for now
