Title:
Cannot use full resolution (2560x1440) of Dell U2715H
Status in linux package in Ubuntu:
Confirmed
Bug description:
While using Ubuntu 19.10 with either MATE or GNOME, I can use only
1920x1080 resolution instead of the full 2560x1440. If extra pixels
are configured, they fall off the right side or bottom of the display
and are not visible. Reproduced on Raspberry Pi 4 with 3GB max
workaround.
