When I said higher gain screens I meant something like the Brilliant White. Indeed it has a very good angle of view. I can't imagine watching anything on a higher gain screen than that as well.
The lens I bought is nothing to specs, I just saw it in a store, it was something very cheep that I bought for fun (just to imagine what a ND2 filter would do as an approximation)...
Indeed I am quite hesitant about reducing the light output from the projector, indeed picture appears sometimes very bright (above all on satellite material and commercials), but on movies that's another story. For ex. LOTR looks perfect, Finding Nemo as well, Ice age propably a bit too bright, but lot of POP
and I am beginning to get used to it.
I am not sure I still want to sacrifice all that for darker blacks
, and relatively speaking, the CR is still the same and I am under the impression the lens affects more the brightness of the picture than it enhances the blacks (that sure is an impression because mathematically speaking that is not true)....
