I'm taking advantage of a couple days off and unseasonably cool weather here in Oklahoma to build a rear projection screen. I have a 9 x 5 spandex screen that I picked up for an experiment in outdoor use. It loses too much light for front projection, but it works well for rear projection. When I tried front projection, I had the 9 x 5 stretched really tight on a 120" x 68" frame. It was probably too much. I'm looking at a 110" screen to use in my back yard. Does it need to be BOC tight or just tight? Any help will be appreciated.
