I too have similar questions. My media room is 12' x 13' with no windows connected to a larger game room. I plan to order the epson cinema 1080 and have a throw distance of 13' with a screen size of 92'. Do I need the 1080p or 720p will do? In addition, in order to get that screen size, I have to zoom by 1.5x factor. How much image quality will I be losing by zooming? Seatings will be around 12-13'. Many Thanks!
