I've tried it but it did not work. I made a custom edid.bin file through CRU on windows, but in rocket League when I click on menus the screen resets/flashes black (as in the monitors hardware does). Also when I select the frame rate target below the vrr window it stays black. It does happen less in in-game 3d scenes I think, but that may be subjective. This happens all the time in Witcher 2. I've been on this for hours. I also tried advice from the following sites later on: https://forum.manjaro.org/t/solved-setting-custom-resolution-for-second-moni...

I of course adjusted it for amdgpu purposes.
I've tried these settings in /usr/share/X11/xorg.conf.d/10-amdgpu.conf according to those tutorials:
Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" EndSection Section "Device" Identifier "AMD" Driver "amdgpu" Option "ConnectedMonitor" "DP-2" Option "CustomEDID" "DP-2:/etc/X11/edid.bin" Option "IgnoreEDID" "false" Option "UseEDID" "true" Option "VariableRefresh" "true" Option "TearFree" "on" Option "DRI" "3" # Option "AccelMethod" "glamor" EndSection
