XRANDR is a commandline utility that allows you to connect to an external monitor or projector. I use this utility since I don’t have any access to gui that allows me to connect to project so I have us xrandr to connect to projectors.

  • This command will list all the connected displays once we have a connected display then we can connect to it using xrandr
xrandr --output DPI --auto
  • --auto auto scale the resolution or you can use your own resolution that is supported by the monitor or projector.
xrandr --output DP1 --mode 1920x1080

For custom resolution.
