What is the usual cd/m^2 brightness for such high-end projectors? Any idea which projectors IMAX uses? When I watch films in IMAX theaters, I find black levels to be slightly better than those of good VA panels without local / micro dimming, but nowhere as good as plasma-level black levels.
I don't quite understand the whole light-blocking. I figured if a scene uses pure black somewhere, then the project would simply not use any light for that section in that scene. I also find plasma black levels to be much deeper than natural black levels of a very dark room (like the one in common or IMAX theater) to be nowhere as good as those of a plasma display. So, no matter how well a project can block light, black levels can't be that good, UNLESS brightness goes over 200 cd/m^2 or something like that.
