Ok i managed to solve this. steps for anyone stumbling on this (amd gpu with amdgpu driver)

  • on /etc/mkinitcpio.conf make sure there is MODULES=(amdgpu) and FILES=/usr/lib/firmware/edid/edid.bin replace edid.bin with whatever you named it.
  • save exit and run sudo mkinitcpio -P
  • reboot
  • on /etc/defaut/grub (if you have grub bootloader) at the end of GRUB_CMD_LINE_DEFAULT add drm.edid_firmware=HDMI-A-1:edid/edid.bin replace ‘HDMI-A-1’ with the port your monitor is plugged in and ‘edid.bin’ with the name you gave to the edid
  • save, exit and run sudo grub-mkconfig -o /boot/grub/grub.cfg
  • reboot
  • done!
