Hello everyone I am new here but from what I have read, I want/need to get a silverstar screen but there are a zillion options and sizes. HD FORMAT. AV FORMAT VIDIO FORMAT DOUBLE DUEL QUAD FORMAT and on and on. I had no idea what I was getting into when I decided to go with a projector I am getting an AE700 and my room is about 17x22 and I want to view movies and HDTV and possibly some satellite TV. I don't really know 100% what I am doing, I have never had a projector or a dedicated room before so I am ready to soak up some advice. I want about a 120 or 130 inch screen and I can do fixed or roll up. Where should I get the screen? Is this going to cost me an arm and a leg? Thanks for your time!
