#!/bin/bash
#reset the monitors to one specific size. for example the following command combines two 1920x1080 monitors
#DP-0 and DP-4 are in this case the monitor names. you can look them up with the xrandr command and rearrange the monitors
xrandr --setmonitor newMonitor 3840/0x1080/0+0+0 DP-0,DP-4
