Mmmmh,yes the instructions in above posts were more oriented toward script writers.
Or, so 2 ways:
- In PlayOnLinux interface: Configure button > (select the virtual drive on the left) > Miscellaneous tab > "Open a shell in this virtual drive" button

POL_Shortcut_InsertBeforeWine "The Name Of The Game Shortcut" "trap 'xrandr -s 0' EXIT"
- In a file manager, go to the directory .PlayOnLinux/shortcuts in your home directory (.PlayOnLinux name starting with a dot it's considered "hidden" directory so you may have to enable the display of hidden files and directories), then carefully edit (say, with gedit) your game shortcut to add "xrandr -s 0" on its own line at the edit, after the POL_Wine ... line
