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?
The OLED TV probably only has HDMI. TVs don’t normally have DisplayPort
There are DisplayPort to HDMI adapters. Like this one:
https://www.amazon.com/dp/B08XFSLWQF
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.
