Screen placement help - I'm going to be using a Sony 10ht with a Greyhawk 54x96 screen. My ceilings are 11 feet high. I would like to have the screen be as high on the wall as possible without it looking awkward, so the projector doesn't have to hang too low. I was thinking I could have the screen bottom be 3 1/2 ft from the floor. That would have the projector hanging down from the ceiling 3 ft. I would rather have the drop from ceiling to projector be less, but don't know how it would look. It there a rule of thumb for this or do you have recommendations? By the way, the seating area is around 15 ft from the screen.
