The gray has a much better black level than either the blank wall (mine was a very pale yellow) or the BW. Both the wall and the BW were quite a bit brighter, as you would expect, than the gray. Actually, I believe it was too bright on the wall and BW. The BW had the so-called "pop" factor in spades but, in my opinion, was spoiled by the too-high black level. Also, the gray rejects ambient light quite a bit better but I still find it best to view in a completely light controlled room. Also, for some odd reason, I found the CCW material to be a tad sharper than the BW but don't see how it could be! I had planned to paint the screen wall and ceiling gray but after getting the gray screen I don't think I need to. Sure, it would further improve the picture but I can easily live with it the way it is now. It looks great! BTW, I believe all the good things I've heard about David Giles and Carada. The screen (88" 1.78 format Criterion) is beautiful, the price is right, and you couldn't ask for better service!
