I am thinking about buying an InFocus X1, or something around that price range for PC/Theatre use, but I have limited wallspace. If I projected onto a wall from, say, 15 feet away...how large would the projection on the wall be? Also, if I incorporated a +/- 1.2x zoom, how would the projection be affected?
go to the infocus homepage, they have a little caluculation thingie that tells you all you need to know
