Actually, the reason they wouldn't show it with the DI enabled is the same one as last year. That the main calibrator Epson uses was claiming that ANSI CR is all that really matters and on/off CR is just a marketing thing as the human eye can only see something like 1200:1. Also, they told somebody I know that the DI is bad because then the black level moves around, but not sure how that matches up with their claims that the human eye can't see much anyway. On Saturday I got to talk to this guy for a couple of minutes before he had to run and I explained some things to him, like that the human eye can see way over millions to 1 over time and can see over a CR range while at the beach and also while going into a dark cave later, so even if the human eye can only see some limited amount at once, a projector still has to be able to do a lot of CR over various images before we couldn't see beyond that. It was clear from what he said that he thought ANSI CR is what matters because it is a mixed image and we watch mixed images, but I explained that ANSI CR is an extreme mixed image compared to average movie content and on/off CR is basically at the opposite extreme, so together they give us some idea of things that are between them (mixed scenes of various levels). He seemed to understand that, although we didn't get to talk for long. Seemed like a really nice guy too and receptive to a different point of view once I gave him some reasons that make sense. I'm still baffled as to how much ignorance there has been and seems to be in this industry about CRs. As I said in another post, I wonder if audio has a bunch of experts or so called experts going around trying to downplay measuring the hiss/noise in silent passages as if that floor of hiss/noise is irrelevant. Arguing against on/off CR (basically the black floor for a white level) seems like close to the same thing to me (except for video instead of audio). ANSI CR is kind of like measuring the hiss/noise with loud rock music. It's relevant, but measures something different than the amount of hiss/noise you get for silent passages, while both are relevant.

I was sitting way off to the side for the Epson. I thought the blacks were pretty good, but could have been better. I would like to see some more of it, especially with the DI enabled. I didn't judge the JVC images a lot at the show. I looked for things like brighter corners on blackouts and didn't see any. I talked to a knowledgeable engineer about the CR they were getting and expect that I'll get to see an early one when a friend gets one for review. I don't worry much about things like whether the colors were calibrated right because they have a CMS. Much like I wouldn't worry a lot about crushed blacks or whites in the SIM2 demo just because that is what I saw with the way they had things setup (or their source material). I often get more excited knowing a projector has a feature I can use (like the manual iris in the JVC or choices for higher gamma than 2.2) than what things look like with the options they used for setup. Just like with projectors like the Sharp DLPs with 3 iris modes. If they showed them with open iris it would only tell me so much as I knew that I would mostly use the projector with the iris closed down (highest CR) if I got one.
Also, they often show material I'm not familiar with, so I would have to check that material out with another projector to compare fairly. Comparing different material on 2 different projectors can really throw you off.
