I'm buying a 10ft (3m) 4:3 motorised screen from Roland. At what height should I have it? I've been reading various articles including Snaggs projector reference, Dolby Labs advice etc. but I really can't work out what the optimum height should be for my screen The Room 42ft X 20ft x 18ft(Pitched). Seating position will be between 14ft-16ft (main seats) and 26ft. I'm using chairs & sofas not cinema seating so positioning is fairly flexible. Although I've had my first PJ (Barco BG801) for a while I've had VERY little time to play with it and I'm not yet familiar with setting it up. I will be getting an 808 as soon as I can afford it. If possible I want to use the top part of the screen for 16:9 so that the drop changes for 4:3 viewing (I next to never watch 4:3, only for really old movies). One article said the bottom of the screen should be at least 4ft from the ground. I've read loads on the optimum viewing angle width ways but can't find anything conclusive on height. Thanks for any input, Mark.
