Sim2 lists Dynamic Black for the Lumis, so no mystery there. Its DI implementation is widely regarded as the best out there. I would like to leave Lumis, dynamic black, and DI out of the discussion. I am asking about the highend Sim2 models: Teatro & the new Cinema line.
There is no color wheel. Lenses should be on par with a 6 figure Titan or Barco. They don't appear to be throwing away a lot of light to get sequential CR spec up. 2 x 400w UHP bulbs nets 7,000 lumens while DPI uses a 3.6Kw xenon bulb and only nets 8,000 lumens. Sim2 has twice the sequential CR. Everything I've read says it's the bulb modulation that's doing it. But what exactly is "bulb modulation". I'm interested in the theory behind it, as well as the real world benefit.
I remember Lon's thread on the HD6Km. The iris would only clamp down after 15 seconds of dark material. So it looked great on paper and the CR rating was true, but real world was far from what the numbers would indicate. I understand DI is never going to be as good as native, and I understand implementations vary. What I'm asking is in similar vein, how good is Sim2's version of "bulb modulation" ? Is it frame by frame? Does it work similar to DI? Or does it just drop the bulb to eco mode when full field black is displayed?
Comparing consumer units to DCI, I hear things like better lenses, better chips, better convergence. There are other PITA issues to deal with, but they're all surmountable. The only performance area where DCI comes up short is CR, so I'm interested how much real world CR difference there is between a high end Sim2 with 10k:1 CR, a Titan Reference which eeks out 5k:1, and the best Barco has to offer which only seems to manage 2100:1.
