Another figure of merit you have to watch is vertical refresh rate.  Many 
projectors don't like anything more than 60Hz.  Most others I've seen start 
having geometry and color problems above 72hz.

Whatever project is settled on, it would probably be a good idea to explicitly 
define a mode at the projector's native resolution and optimal refresh rate 
in xorg.conf.
