I'm thinking about purchasing Epson Home Cinema 1080 UB projector, and trying to decide how big of a screen I want to go. The max I can go will be 134" diag. (16x9) I'm going to get an elitescreens Cinetension 2 electric screen with a gain of 1.1. I will be mounting the projector between 15 and 16 feet.
The room will be more of a multipurpose room in the basement (16'x35'x8', screen wall on the 16' wall), but I will be able to control all lighting in front of the projector at all times, but there may be some times when lights will be on behind it, in party situations. The screen will also be coming down over a window, but it will have a black out shade, and has one of the basement well things around it on the outside. We haven't picked out our paint for the house yet, but we are leaning towards a brownish shade, white trim, most likely a white ceiling.
Will I be ok with a 134" diag screen or should I go down to 120" diag? If I go down to a 120" will I be able to get away with a lower lumen projector (the non-UB epson?).
Here is a drawing of the space. Will the stairs cause an issue with ambient light?
Thanks!
