Two days ago, I installed the latest release of CachyOS with Plasma. I noticed that I have support for 4K+120Hz+HDR+VRR, even though my graphics card is connected to the TV via HDMI 2.1. Is this some kind of bug, or did AMD manage to add HDMI 2.1 support to their drivers? One of the things that kept me on Windows is apparently no longer an issue for me. I run Helldivers 2 via gamescope - HDR can be enabled, and judging by the UI on the LG C2, both VRR and HDR are working and the screen refresh rate changes according to the FPS.
