Right now, I'm projecting onto a wall. A search here and on AVS Forum yielded a lot of stuff about DIY screens, but I'm not sure what's best for my needs ... hence this post. I'm using a Sony VPL-W10HT LCD projector. I originally planned on attaching trim pieces to define a 16:9 rectangle on the wall, and paint that trim in flat black. Then inside the screen area, paint with the Behr Ultra-White paint described over on the AVS Forum. But then I read that these paint-based screens don't have sufficient gain to use with the 10HT. There was some talk of gray paints, to get the benefits of a gray screen, but again - not enough gain for a 10HT. The "ideal" option is one I can't afford - a Stewart Firehawk screen. I wouldn't be surprised if that screen, in a 120" 16:9 format, would cost me more than the projector did! Then there was a dizzying array of other options: - A guy who goes by "KBK" selling a proprietary "screen goo," a paint formulation with some sort of reflective particles suspended in it. I'm not sure it can be applied to a vertical surface like a wall, though. - Certain plastic wall materials, often used in constructing bathrooms, being used to yield a flat white screen surface. But these weren't available in 120" 16:9 sizes, and are not as pure of a white as the Behr paint. - Screens made of white "blackout" cloth stretched over a wood backing. Any suggestions on what I should pursue? Should I stick to my original plan, paint with "screen goo," or start saving up for that Firehawk???
