I got my OLED yesterday and so far all three HDR games I’ve tested (Tetris Effect, THPS1&2 and modded Control) won’t allow HDR to be enabled. I cant see any workarounds for them so far either. Hopefully this will be improved with time, but as a start it seems HDR support is about as annoying as it is on desktop PC!
Tbh the protocol for enabling HDR on normal desktop environments on linux isn’t even finished yet. Not sure what valve is using to enable HDR on the steam deck but I’m not surprised it doesn’t work everywhere. I think in 2-3 years there will be plenty of games where this will work out of the box.
Valve is using their own HDR implementation in Gamescope, literally nothing else really exists.
Ah I see. That makes sense.
