I need help making decision on screen if I should go with Elite Screens ER120WH1 or ER135WH1. Color of ceiling is Antique White and walls are light brown. Ceiling height is 94 inches and room width is 132 inches. Will be installing cabinets 22 inches high from ground. Is it OK to get 135 Diag. as it will be close to the wall or 120 Diag. screen is a better option? I got Sony VPL-HW55ES and will be installed on ceiling 17.5 Feet away from screen. Will be getting CineWhite screen.
