"If full black fields have the same luminosity on both projectors it follows that the On-Off of the Lumis is in the 60000-150000:1 range (Lumis white is 3 times brighter than RS20, and a RS20 measures easily between 20000:1 and 50000:1). It also means for black a whopping factor of 18 to 30 is used if native On-Off is 5000:1 as reported. Is all of this the case?"
These numbers correspond with subjective impressions being reported, but they far exceed spec's.
It's truly a mystery how this pj does what it does.
"It is really uncanny how the dynamic black works. Because it is a frame by frame analysis, and source dependent, the better the source, the deeper the blacks get."
How does it react when a very dark scene with no bright areas suddenly gets a small but very bright feature?
