I found the Cine4Home numbers on the Panny very interesting.
In a color-correct mode like Cinema 1@D65, he measured:
~3300:1 static on/off, and ~13,000:1 dynamic. That is to say a 4x contrast expansion using a DI.
In dynamic mode, he got ~5900:1 static on/off and ~60,000:1 dynamic. That's a > 10x contrast expansion. I wonder if this means that dynamic mode has a big effect on DI usage. I don't know how bad the colors are in dynamic mode, but I hope its a lot better than in the past, where the colors were almost cartoonish, with huge green push and bad skin tones - basically unusable for watching movies (imho).
Also since there's such a big difference in on/off between these modes, I wonder if there will be a similar difference in ANSI. Does ANSI drop to 1/2 in color-correct modes (probably not quite that much, but I wonder how much it drops)?
As a side note I expect the Epson 7500 to put out very similar numbers both in terms of brightness and contrast. The only real question is how does the DI and the various modes stack up.
