Bug Description
Following on from https:/
When I plug a Dell U3414W screen into my Dell XPS 13 9343 display port the screen does not turn on when I enable it's native 3440 x 1440 in the display settings.
Lower resolutions correctly work such as:
2560 x 1080
1560 x 1440
I also found these messages in the dmesg log:
[ 308.637781] [drm:intel_
WORKAROUND: In Settings menu under Display disable "DP 1.2".
