How to change/add a screen resolution
Posted: Tue Sep 24, 2013 6:45 am
ive spent the last hour or so trying to change the resolution. the monitor im using can handle up to 1920x1200 but the highest i can select in the nvidia server settings is 1368x768. ive been trying to chane the resolution through the terminal using xandr and i think ive made progress but im stuck. This is what xandr currently looks like
it looks like the resolution ive tried to add has been added under the wrong port. they appear under hdmi but i wanted to add it to VGA-0.
does anyone know how i can fix this?
ive tried
