I recently visited a guy who had a Stewart back projection screen. It looked almost as black as a tv-screen and the picture looked rather good even with some light in the room. I noticed some hotspotting, and some glare from the glossy (looked like glass) surface, but else this was a very elegant integration of HT in a living room. The big BG-1200 projector was ceiling mounted in the neighbouring office, and couldn`t be heard in the living room.


Any opinions on picture quality differences between front and back projection?

This sounds quite a bit like a Stewart BlackHawk Rear Projection screen. I'm sure it looked good, however I have always heard that Front Projection will almost always look better than a Rear configuration (barring any ambient light problems). Typically, with a RP setup their is a higher level of hotspotting, as well as poor off-axis viewing over it's FP counterpart.


Again, when lighting conditions are controllable, and you simply have room for the projector on your floor or ceiling, a front projection install will be preferred.

Hotspotting is no more a necessity with RP than FP; the same set of tradeoffs vis a vis gain/brightness/hotspotting exist. But the RP will be much more tolerant of room light.


Hotspotting and resolution loss can be avoided with a diffusion screen.


There's lots of info on RP at the Dalite and dnp web sites; a google search on "rear projection screens" will turn up their sites.
