the problem youll run into is that the image doesnt go the full size of the screen for some reason. its always smaller that the projector screen, exactly the same when run through the TV through the apple TV. Dont get me wrong photos and videos put through apple tv seem to output in full screen but when mirroring from ipad (apps) to apple tv through the projector it doesnt output full screen.
I was hoping that this was something that would be fixed with the release of IOS 6 hopefully
