$ xrandr --newmode CustomMode ...
$ xrandr --addmode VGA CustomMode
$ xrandr --output VGA --mode CustomMode
This creates a custom modeline, adds it to the list of available modes
for the VGA output and then turns on the VGA using that mode.

Nope; just plug the projector in and the laptop will detect the presense
of the projector automatically. You should never need to use the above
