Thanks to member Larry Newcombe I had a chance to look at a 6710 last night for a few hours. DarinP and Tyler Pruitt were also with me. Obviously we didn't get to look at everything but here are some observations I had.
New menu system was hit or miss. If you're used to the old one this one can be frustrating at times to find things. I did LOVE that they took the focus window and moved it to the top right if you're not using the internal pattern. This always annoyed me and now you can look at dead center to focus. Speaking of focus, I found it a tad harder due to the new pixel size. Harder to see the pixel definition with the new fill but I still managed to focus it VERY sharp. Larry's projector was quite good with pixel focus and convergence from what I saw.
We didn't have any issues with HDMI last night despite switching the resolution feeding the projector several times. Larry said he has had a few issues since he got it but we didn't have a single glitch last night. He was feeding the projector HDMI from an Oppo 93 via a Darblet.
We used the standard color gamut and the 2.3 preset for gamma and we literally didn't have to touch a single thing for calibration. We ran thru a full measurement set for grayscale, gamma and gamut (including saturation and color checker) and the projector was almost entirely less than a deltaE of 2 for color and less than 1 for grayscale/gamma. Incredible OOTB performance in this regard. We did have to raise the "dark level" adjustment in the gamma screen to get digital 18 to show up (brightness and contrast were left at 0) but like previous models we were unable to get digital 17 to show up. I wonder if this is a LSB issue with the JVC similar to what the Marantz projectors used to have.
We did some rough calibration measurements. With the light output set for about 13 fL (low lamp iris at 5) we achieved about 40,000:1 (LOTS of room for error with the meter on this) and with the auto iris in mode 2 we got somewhere around 300,000:1ish. Again, these were rough measurements.
We did a lot of watching with Auto 2. Auto 1 was a bit too aggressive as Zombie has pointed out but Auto 2 worked quite well. The first scene we looked at was the interrogation scene from The International near the end of the movie. This always created very obvious problems for the dynamic iris in the Planar 8150. With the projector's HDMI mode in Standard (clipping at 235) we saw some very obvious gamma issues as the projector tried to figure out what it wanted to do. We also saw obvious clipping on Clive Owen's nose, but it wasn't nearly as bad as the Planar. The Planar makes the bridge of his nose look like a big clipped patch of white. The JVC kept the color of his skin but clipped all the detail. If we put the HDMI mode into Super White the results were much better. It didn't have nearly as much gamma shifting and the clipping on his nose was far more contained and not nearly as intrusive. Those of you evaluating the iris may want to experiment with this if you're seeing artifacts and are using Standard for the HDMI mode.
We also looked at Riddick. We didn't notice any issues at all with the iris in the scene where they have him chained up. Shadow detail was exceptional throughout this entire scene. The dynamic iris definitely helped extremely low APL scenes that we looked at but I don't know how much it was adding to the mid to low APL scenes. We didn't get the chance to play with clear black.
Overall I was really impressed by what I saw of the iris for JVC's first go around. It clearly improved black levels with black outs and extremely low APL scenes but rarely if ever called attention to itself. Thanks again to Larry for letting us monkey around with his projector last night.
