My graphics card is an AMD RX 5700 XT, which does not support HDMI 2.1 (4k120hz), but I don't think that's relevant. I'm using Windows 11 Pro. My TV is an LG C2. The Game Optimiser mode of the TV is active.
I tried it with many games, and also with auto-HDR. When Windows is in 120 hz mode (at 1080p), Windows' HDR button switches back to "off" right after I turn it on. HDR only works with 60 hz mode. Any ideas? Thanks in advance.
