I have a similar situation, using the generic `nv' driver rather than
the blob. I am able to do presentations at limited resolutions. I think
the best I've got on a projector was 1024x768. Anything higher results
in the bars & boxes as you describe. You might also see if limiting your
color depth makes a difference (just guessing on that).

FYI, I'm not using the Gnome GUI, just working with xorg.conf.

I was thinking about this earlier.  Since the LCD screens on laptops always refresh at 60 Hz, maybe the projector does not expect to run selected resolutions at 60 Hz.  I talked with Joe earlier and he told me he had the same problem until he did something in the projecters menu to fix it for him.  Most curious.
