I am installing a Sony Black Pearl projector. My local dealer is a Stewart and Da-lite dealer and would like to end up with one of these. The Da-lite he priced me was about $75.00 more that I could find it for on the internet which is acceptable to me to buy local. My room is 22'1" by 14'1" with my front row seating at approximately 14 feet. I have light control in the room. I am clueless on screens and would appreciate you find folks giving me some feedback on which screen I should end up with and if you could give me some reason why. I like to have some clue as to why I end up with the screen I do. Thanks for any help you offer.
