Glass beaded = diaster? (1 Viewer)

[Colin T]

Hello, first time posting here. I just set up my projector (viewsonic pj1075, not bought for this purpose) and have encountered a problem. The picture is quite grainy on my screen, a Dalite Model B glass beaded 84" diagonal. From what I've found on these forums, there are two problems with glass beads: graininess and excessive refraction. That's another problem I have, the room is incredibly bright. My projector is mounted around 3 feet above and 2 feet behind the viewing area and the screen is 13 feet from the projector. I have complete control of lighting in the room. Since the screen is brand new, should I return it for a matte white? Any other suggestions. Thanks.

After viewing some more, I've discovered that much of what I had attributed to graininess is really pixelation. Not to say the graininess isn't there, but the pixelation is much worse. What I mean when I say "pixelation" is that when there's an object in the background (like a person), it's possible to view the individual pixels. This projector was bought to use for presentations. It's a XGA DLP, so perhaps that's responsible for the problem. Since this is a 1024x768, 4:3 projector and it's displaying a 16x9 image (it letterboxes it) is it possible that those objects have such a low resolution that pixelation occurs? Thanks.

Please just tell me if switching from glass beaded to matte white is a good idea. If I don't do this soon, I lose the option. Thanks.
