Does AMD not support Display Port? I'm not an expert on this, but that sounds to me like the superior technology.

TVs don't support displayport, so it makes Linux PCs like the Steam Machine inferior console replacements if you want high refresh rates. A lot of TVs now support 4K/120hz with VRR, the PS5 and Xbox Series X also support those modes.

(Some games support 120, but it's also used to present a 40hz image in a 120hz container to improve input latency for games that can't hit 60 at high graphics quality.)
