Well, I went down to a distributor I work with locally and had the chance to watch them play a JVC-X70 PJ on a Screen Innovations Black Diamond curved screen. I don't know a lot about that screen, but it was a dark grey screen material and looked brilliant in both full light and in darkened viewing.
My concerns were that the curve was evident the whole time and didn't add much to the experience. I always thought I liked curved screens but after closely analyzing it, I could see light spilling onto the felt bezel of the screen where the curve happened. I didn't care for that. On a purely image basis, I did like what I saw, but it maybe looked a little dark. Blacks were awesome, but whites seemed less brilliant than they should be. I don't have much to compare it to, but they carried SI, Vutec and DaLite. Unfortunately, only the SI BD was on display. I'm not sure if I'm better off looking at these brands or going with a Stewart.
If my budget is about $10K for projector and screen, and I'm thinking of the JVC LCOS PJ's like the X70, for instance, in a fully light-controlled room (75% films on Blu Ray and 25% HD cable TV), does it really get much better than getting a Stewart? I've never heard one bad thing about their quality, and I'd rather save up a little longer to get something that I'll stick with for years, rather than upgrade three or four times to get up to that screen. I've done that before on things and it's cost prohibitive. I have also read a litlle about SMX and their Acoustically transparent screens seem to get very good reviews and comments, as well.
Thanks for all of the great information to everyone who contributed! It is extremely helpful!
