Hi all, a few times now I've been asked to give a presentation and I want to do it from my iPad instead of a laptop. My understanding is that I can simple use the hdmi adapter and a digital cable, the same one I use for my flatscreen to cable box at home. The problem seems to be on the projector side where they never have a digital input on the projector. Has anyone figured out how to get this working so I can go to any hotel and give a presentation from my iPad? Shouldn't this be a realty and standard by now?
