I was really amazed by the pop/sharpness of my Mits DLP on a blu ray like 'Lucy' and was afraid I was gonna give some of that up with the JVC, but alas, it was about the same pop/sharpness. On first comparison, the JVC seems to have slightly less pop, but after calibration (especially gamma cal), the pop improved and was about the same as the Mits.
The JVC has a much better lens than the Mits. So even though the Mits is a single chip DLP, the focus uniformity of the lens was not good. On the JVC, the focus uniformity was excellent. Convergence was pretty good...only the blue was off a bit, but I shifted the blue a whole pixel and it was better than the non-shift. Overall I got the best of the Mits and the best of the DLP in one.
Now, I know the Mits HC3800 isn't a top line DLP, but my JVC is a 2014 model. JVC's have been getting sharper and pop'per over the years, and that's no exception for the JVC models newer than mine. They also have way more firepower/lumens, which is a big part of that 'pop' too.
The contrast advantage isn't just for dark scenes. Mixed scenes benefit---have more pop due to it. And a huge native on/off contrast is not negated by less ansi contrast of a JVC. There are many articles and threads here about how on a projector, a 600:1 ansi, 3000:1 native is blown away by a 300:1 ansi, 30,000+ native projector ---even on mixed scenes.
I have the darbee too and the JVC benefits greatly from it. JVC's have full motorized lens control and lens memory and mine has an auto lens cover.
The Sharp Z30k seems to be a really nice PJ. I bought my JVC used, but thought about a used higher end DLP with DI like yours. I knew it would be an improvement over my Mits (which has no iris..manual or DI), but ultimately went JVC due to my love of sci fi. Even so, most movies (not just sci fi) have lots of dark scenes, so those blacks and contrasts really come through.
Now that I've gone black, I can't go back
Unless there's some major development in DLP tech, I can guarantee that my next PJ upgrade---a few years down the road, will be a JVC.
