Title:
Quadro 420 limited to 1280x1024 for each of the 4 displays
Status in nvidia-graphics-drivers-340-updates package in Ubuntu:
Confirmed
Bug description:
Nvidia's specifications for the Quadro 420 state:
"Drive up to four 30’ displays at 2560x1600 resolutions"
After a couple of days trying variations, I discovered the only way I
could get 4 displays working properly was to set them all to
1280x1024. If any of the 4 were set to a higher resolution via the
System Settings -> Displays -> Resolution, it would do various buggy
things.
Here's my configuration:
# apt list --installed|egrep -i "nvidia|nouveau"
