Thanks. This is what I'm currently trying without too much luck (the
projector image is cropped)!

Yes, but I suspect that magic only happens because you are using s-video -
using the VGA output, Nvidia display settings only lets me choose from
resolutions lower than or equal to the projector's native resolution:( I
don't know if I could force a higher resolution by modifying the xorg.conf
file instead - something I was hoping to avoid, since it has given me lots
of trouble in the past...
