Exec=sh -c 'xrandr --output VGA1 --mode 1680x1050 --rate 59.95'

If this file is blank, copy and paste the text above into it. Change the output to your video connection (VGA, DVI, HDMI) and the mode and rate to whatever you set in Display Settings. Save.

Copy everything in the Exec line from single quote (') to single quote (').
