Question for JHouse:
I'm considering the High Power, and one statement you made above intrigued me: "It has ambient rejecting properties that are pretty decent also." This issue is of prime importance to me. While ambient light sources can be well-controlled, my room has light-colored floor, walls and ceiling, so I'd really like to minimize light from the screen hitting those surfaces and then reflecting back to the screen. I just bought my first PJ yesterday(a 7205), and putting samples from Da-Lite and Carada over our current screen(a bare, off-white wall), I noticed that while black level was elevated with the High Power compared to the others, the white level was elevated more, which seems like a good thing. Now, if the retro-reflectivity of the screen could reduce light reflecting back from the walls, etc., that would be icing on the cake. Do you think black levels would improve with the High Power because of this?
If so, the only down side I can see to the High Power is that, due to a funky arrangement in the room, my wife would be about 4' offaxis @ 15 feet from the screen. Readings with a spot meter confirmed that brightness from there would be about 35-40% reduced from 2' offaxis.
