Has anyone out there got a projector and screen set up?? Thinking about investing in both and setting it up in my bedroom but tbh I haven't really got a clue about it!! Been reading up and it seems I can get a screen and projector which will support 1080p hd and has ports for Xbox, bluray players etc for around £150. Seeing as the screen itself is 80" I'm thinking this surely can't be correct. Why wouldn't everyone buy one if you can get HD experience on an 80" screen for £150 when tvs are in excess of £400??
