Careful with running resolutions that are not supported by your graphic card. 
Try run just "xrandr" in dom0, it'll print out all your supported resolutions.

First confirm in dom0 terminal if it works, then make a script that you can 
keybind, autostart, or turn into an icon shortcut. Put it like this;

"xrandr --output eDP1 --mode 1920x1080"

Above resolution is an example, change it to one your card supports. Also the 
same command that finds your supported resolutions, also tells you your 
screen's name. Be sure you got the screen name correct, it will only work if 
you do it precisely. For example, are you sure it's not eDP1 instead of eDP-1? 
It can also be named something else entirely, i.e. HDMI3, you need to confirm 
to be sure.
