    ive found that the issue in my experience is that X11 only supports a max of 4k60, but Wayland supports 4k120 and beyond. I dont think the cable matters as the same cable im using works on windows with 4k160.

      It’s a matter of cable bandwidth. 4k120 4:4:4 requires more bandwidth than hdmi 2.0 can provide. You can drop down to 4:2:0, but that’s a pretty bad experience and ruins the image quality.

      I’ve been using an adapter cable, but it’s really flaky, I don’t know if it’s a bad cable or what. But a normal hdmi cable just plain works on Windows, since the windows amd driver supports hdmi 2.1.

        yes, that is a valid factor. i meant more towards the type of cable doesn’t mater. but yes an up to date spec of the cable is also just as important
