Answer 1

Well, I'm guessing your projector has a USB input for some other purpose than sending video through it.  Perhaps it's used to control the projector (focus, zoom, etc.).

The problem is that USB doesn't have enough bandwidth to carry raw video.  It has plenty of bandwidth to carry compressed video (mpeg-2 say), but that would mean that the projector would have to have an MPEG decoder in it, and I don't think projectors usually have those in them.

I could be wrong, of course.  Good luck.

Answer 2

I am in agreement with Noodles, your projector would have a USB input for firmware upgrades or some other purpose, the simplest way to hookup your computer to the projector would be with a standard VGA cable, as most projectors have that as an input connector.
