My room dimensions are 18x11 and my screen size will be 92" (80x45) my projector will be mounted approximately 14' from the screen , the ceiling height is 6'-9".I would obviously like to put the screen and the projector as tight to the ceiling as possible . My projector is a sony hs20. i probably will build an adjustable ceiling mounted shelf.Can someone tell me how close to the ceiling i can mount the projector without too much compromise on picture quality?
