Forget, for a monent, the numbers... how does it look? For simplicity sake, lets assume a good CRT ( they need the gain the most), lets say a 9" CRT on a screen 107x60". Lets also limit the curve to the horizontal only ( no toroidal's).
1) must you be sitting in the center to get the proper effect? Does the curve limit your viewing angle, and if so, how much does off angle viewing suffer (remember the awful brightness variations on the toroidal Kloss Novabeam screens as you move even a few feet up-down-sideways!) ie. if 90% viewing is dead on centered,8% of the time someone sits off center but still within the screen width 12' back, and 2% of the time intoxicated but fanatic fans are all over the room and floor looking at all angles at the super bowl...WHAT DOES IT LOOK LIKE?
Could someonr with a curved srceen just walk all around and tell us dreamers what it looks like from MANY angles...please?
2) Would you get and advantage by curving your existing gain screen (ie. 1.3), or would you have to go up in gain (ie 2.0) and curve to help the problems associated with the higher gain?
3) How much curve? I have always assumed you would take a string centered on the projector and make the screen distance equal all across...True or more complicated?
In case it isnt obvious, I'm a CRT fan who would love to go digital, but have yet to see a digital projector with as good a picture, but REALLY want to go to a 107x60 minimum screen. I'm looking at a 9" but worry about it with a 1.3 flat screen. I would feel better with a 2.0 and would love it if the curve helped the situation, but I wouldn't do it if the curve really screwed up and gave me much "Kloss toroid brightness variation). It sure would be nice to have someone with roughly the same specs give me advice.
Finally went digital: RS20, ISCO IIIs, DIY 10.5' wide torus screen, Stewart StudioTek 1.3 G3 with 4 way masking and adjustable image size
