iPhone? Xbox? Blu-ray? You got it, this'll project the living bejeezus out of it.
If you're looking for something to project any video signal to within an inch of its life, check out the Optoma GT200. It can project the face off of your iPhone, game console, Blu-ray player, cable TV signal, whatever. Pretty much anything you can watch, the Optoma will project into a bloody pulp - if a bloody pulp was a crisp, bright WVGA or HD video signal.
For an easy, affordable projector that can project a wide range of video signals nine ways to Sunday, tey the Optoma GT200: the projector that'll project the holy hell out of anything.
