Remove the '1280x800' video mode.  It is likely that the LCD Projector
is a standard 4:3 video device (this is implied by being a VGA device)
and is not going to handle a (near) 16:9 (wide screen) video mode.
Unless the LCD Projector is really, really, really old, it should
handle 1024x768 without problems.
