Before creation of this issue, I found a similar, almost identical, issue on the freedesktop bugzilla. Found here: https://bugs.freedesktop.org/show_bug.cgi?id=91896 A possible bug was disovered on comment 13: https://bugs.freedesktop.org/show_bug.cgi?id=91896#c13 "OK, the problem seems to be that amdgpu_connector_is_dp12_capable returns false because adev->clock.default_dispclk is set to 50000." A patch was submitted here: https://bugs.freedesktop.org/attachment.cgi?id=118844 Thanks! |
Created attachment 188111 [details] xrandr I currently own two Dell P2715Q monitors, each having a native resolution of 3840x2160. When using DisplayPort on my AMD RADEON R9 FURY X, the resolution is not a known option. I previously had an AMD RADON R9 290X and it was able to detect the correct resolution of both monitors. Attached is my xrandr --verbose" to show that the AMDGPU is not handling the correct resolution available. Please also note that while 1920x1080 is a selectable option, it is running in interlaced mode, 1080i. I have had some success with creating my own monitor xrandr profile for each screen. It does temporarily resolve the issue, but it not persistent after a restart or at login.
