Trying to increase my refresh rate to anything higher than 60hz causes my monitor to lose signal. On Windows I can set it to 1920x1080@120fps with no issues. I am running KDE with Wayland but have also tried this with Cinnamon running Xorg — the result was the same.
On Xorg I’ve tried generating and using a custom resolution using cvt and xrandr, both with and without reduced blanking and neither seemed to fix the issue.
I’ve also tried extracting the edid file using Custom Resource Utility on Windows and loading it using a kernel boot parameter but it kept giving me the following error:
[ 5.702338] amdgpu 0000:03:00.0: [drm] *ERROR* [CONNECTOR:75:HDMI-A-1] Requesting EDID firmware "/lib/firmware/edid/edid.bin" failed (err=-2)
Apparently this error code means that the file isn’t in that location or can’t be accessed. I’ve rebuilt initframfs using dracut many times with install_items+=" /lib/firmware/edid/edid.bin (and also /usr/lib/) and tried enabling early kms with force_drivers+=" amdgpu ". The issue persists.
This is what kscreen-doctor outputs:
