After analyzing the dmesg outputs without the above kernel parameter I've noticed that, on boot, my second monitor (connected on HDMI-A-2) was detect= ed but went on some kind of loop reporting that the Edid was changed.

[drm:drm_connector_update_edid_property [drm]] Updating change counter to 41 After some googling I've managed to get both monitors working correctly wit= hout amdgpu.dc=3D0 by forcing edid files extracted from both monitors using these kernel parameters: video=3DHDMI-A-1:e video=3DHDMI-A-2:e drm.edid_firmware=3DHDMI-A-1:edid/edid1.bin,HDMI-A-2:edid/edid2.bin Couple more details that may help: - both monitors are the same model BenQ GW2470 - they are both connected via a HDMI 2.0 cable from the same maker and are = the same length - I've decoded and compared both edid files and the only differences are the "Display Product Serial Number" and "Checksum" --=20 You may reply to this email to add a comment.
