This is really frustrating. This is the only thing holding Linux gaming back for me, as someone who games with a AMD GPU and an OLED TV. On Windows 4k120 works fine, but on Linux I can only get 4k60. I've been trying to use an adapter, but it crashes a lot.

AMD seemed to be really trying to bring this feature to Linux, too. Really tragic that they were trying to support us, and some anti-open source goons shot them down.

are you unable to use display port?

[-] Celestus@lemm.ee 36 points 6 months ago

The OLED TV probably only has HDMI. TVs don’t normally have DisplayPort

There are DisplayPort to HDMI adapters. Like this one:

None of the adapters seem to support VRR though, for whatever reason.

Same reason probably: the HDMI forum

Freesync works for me with that cable, but I have some awful cable training problem or something. Everytime the screen is reset, it refuses to go above 4k60 or turn on freesync, and it'll only work again after I have the screen connected for a few minutes. So whenever I start my comouter, have to switch down 4k60 and wait like half an hour to be able to use high refresh rate. It's been doing this for months.

I don't know if I have a bad cable, weird interference, or if FRL adapters are just flaky.
