Even though I'm (newly) dirt poor, I just ordered an Optoma HD131Xe. That's a cheapo DLP projector, rated at 2,500 (marketing, I presume) lumens. I'll be wall mounting it about 8 feet up the "back" wall of my little bonus/media room, and throwing an image about 11 feet over to the opposite wall. The room's about 12.5 feet square, and has a vaulted ceiling. The side walls of the room are 8 feet high, while the end walls (ie. the projector and screen walls) are about 11 feet high at the peak. I'd guess that the upper corners of the screen will be 3-4 feet from the nearest part(s) of the ceiling. More like 6 feet in the middle of the screen. So, that's good, I think.
The room currently has light beige walls and ceiling. And carpet, now that I think about it. I don't want to turn the room into a black hole, but I do plan on painting the walls something much darker. Maybe something like olive drab? Not super dark, more... medium-ish. I'd prefer to leave the ceiling beige, since it's way the heck up there. I know that's a problem. I'll black out the room's one window, but I would vastly prefer it if the screen was usable in dim (but not dark) condtions. I'll be using the screen during the day, and don't want to have to seal myself in completely.
I guess I'll have to build a screen, mostly because I can't afford to buy a nice one. 92" would be the center of that PJ's zoom range, and I think might be a good size given that we'll be sitting 9-10 feet back. I'm gonna project on the bare wall for a bit while I decide if I should go any bigger, but staying with a screen size that can be cut from an 8 foot piece of sheet goods shouldn't cramp my style at all
The handy dandy projector calculator
claims that I'll be looking at 31 fL with a .7 gain screen, and 44fL if I use a 1.0 gain screen. Pretty bright, isn't that? (I'll want to use "ECO" mode, however. So I won't have quite that many lumens in actuality. Maybe more like 1,500? I don't actually know.)
So, I should go gray, huh? But how gray? I'm a bit overwhelmed by all the paint formulations in this forum. Do I need something "shiny" to boost the gain back up, or would flat gray do me fine?
I have one of these
Wagner sprayers. Not sure if it's suitable. I've got plenty of rollers as well.
Advise me, please? Mostly about what paint you'all would recommend. (I'm in north Georgia, if it matters.)
