Ok, now I'm really stumped! I exchanged the 1.0 gain screen with a 2.5 gain glass beaded screen and it's still not bright enough. There is no hotspotting or color shift, and the image is brighter than before, but with a 1.5 gain increase I expected it to be brighter. I still need to run the projector at the point of blooming (brightness at 7, contrast at 5) to get an acceptable image. I thought I would be able to turn the settings down a notch or two, but I guess not.
So, now what? Should I go up to 3 or 3.5 gain? If so, who sells those kind of screens? I need it to be pull-down, not fixed, and Da-lite only makes up to 2.8 gain according to Eric Lang at Projection Systems.
Another thought that crossed my mind was that Da-lite may have made a mistake and sent me a 1.5 gain instead of 2.5. It was drop-shipped directly from Da-lite and the paperwork doesn't specify the gain, it only says 'glass beaded'. Is there a way to test what gain the screen has? Any suggestions will be appreciated.
The projector is sitting on a 20" high coffee table. The bottom edge of the screen's viewable area is 25" from the floor. This placement is temporary. I plan to mount it on the ceiling in about a month or so.
I don't know if all Da-lite glass beaded screens are retroreflective. If they are, does that mean I'll need to get a new screen when I ceiling-mount the projector?
The room walls and ceiling are painted off-white. Painting them on a dark color is not an option since it's the living room area and my wife would put me AND the projector on the sidewalk if I did that. It was hard enough to get her to agree to have a projector in the living room to start with! http://www.avsforum.com/ubb/wink.gif
