Hi, I'm in the process of planning out a home cinema set up and have an Onkyp Av amp which has one HDMI output. This has been fine up to now but we're going to be adding a projector so I'm going to need to take the hdmi feed to both the tv and projector. Do I just need a splitter that will feed the signal into both devices at the same time (only one would be on at a time. I'd really like something that doesn't need any power. I've seen splitters on ebay for ten to twenty quid. Is that all I need? If anyone could reccomend one that would be fantastic. Ideally as cheap as poss, my budget is already spiralling! lol.
