Bug ID: 104881 Summary: AMDGPU FIJI doesn't support higher resolutions past 1920x1080 Product: Drivers Version: 2.5 Kernel Version: 4.3.0-rc2-1.g2b75354-desktop Hardware: Other OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: longshot902@gmail.com Regression: No
Created attachment 188111 --> https://bugzilla.kernel.org/attachment.cgi?id=188111&action=edit 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.

--- Comment #3 from Jeff Nelson longshot902@gmail.com --- 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!
