I know about all the numbers, angles, gain, etc., but what does it subjectively look like?
1) How much more light will a 2.5 get you over a 1.3 (which I now have)...ie is it as much as the difference between a 9' and 8' CRT (brightness only...I know it won't help resolution). Or would it effectively get you enough on screen lumens to go from 96" to 107" wide (not diag)?
2) More important...how bad are the off axis artifacts? I sit in the sweet spot (13-14') of a 107x60 screen...when I have guests, they get that spot and I move to about 9 or 1 screen width back from either side (straight back from the edge...so looking at the near edge, I'm at 0 degrees, but looking at the far edge, I'm at 45 degrees roughly). These are worst case angles. Even on my 1.3 gain screen I notice NO objectionable gradients of brightness or color... would a 2.5 screen look much different from one end to the other?
How about an extreme example... at super bowl parties 30 people sit way too close, on the floor, and way off to the side, and the picture always gets raves...would a 2.5 screen make it unwatchable at these extremes or would it still look good because of the huge size and nature of "viewing material"?
Basically I have the 107x60 1.3 screen up now but only use 80x60 on a 7" CRT without scaling...and want to move up to either a 9" CRT (worried I may need the high gain screen with its problems) or to a DLP (minimum 1024...prefer 1280) with more lumens and hopefully the gray screen mentioned in other posts to get the blacks and contrast I know and love with CRT). I figure street price on the Dwin or Seleco will be about what a used 9"CRT is...and hopefully the 1280x720 RPTV DLP chip will be available for FPTV this spring.
I welcome anyones opinions and experiences.
