Thanks Alec and Andréas. That certainly seems worth a try!

I don't seem to have a xorg.conf file, but I assume the OS will use one 
if it finds one.

So, now for the million dollar question ...

How do I know the right settings for a xorg.conf entry for my BenQ W1300 
projector at 1920x1080? Those HorizSync, VertRefresh, ModeLine and 
Option settings look like things that you don't want to get wrong!!

Thanks,
Damian
