The decision to box in my projector was weighing on me, and I wasn't comfortable with my screen size decision. I needed to break out the projector and test for screen size and make a final decision on the projector box. So... I busted out a ghetto-screen aka a WalMart sheet:
Then I setup the projector on a TV tray and used my amp and one of my side surrounds for a center channel. I brought my XBox 360 down for a 1080i (best I have right now) test of 16:9 and 2.35:1 content.
I fired up the projector and *wow*. I'm thrilled and this is on a completely unfinished room on a bed sheet. Only 200 thread count. Imagine if I went for 400! Pictures of the "screen" were taken in auto mode on my camera rested on a tripod and the kit lens. I have a Canon Digital Rebel XTi.
I zoomed to match the image height of the 2.35:1 projected image of the movie. I don't have a lens, so this was just to gauge screen size.
After all that, I decided that it wasn't worth risking my projector to put it in the box I had constructed. So I cut it out and proceeded with drywall repair.
I'm totally torn on screen size now. My screen can be 9' wide. At 2.35:1 that's 46" tall and ~118" diagonal. Keeping a constant height setup, that makes 16:9 ~82" wide by 46" tall and ~93.5" diagonal.
If I keep the 9' width and make that my 16:9 size, then just project the black bars for 2.35:1 content and have a 108" by 60" 16:9 screen at 124" diagonal!I realize this is a personal preference issue, but what do you (my readers!) think?
