1. The Ansi Contrast improvements is for ALL 3 new projectors.
2. The top slider on the tone map HDR sub menu is for compensation for Large screens, so Manni got this right...
3. The installation holes on the back of the unit are in the exact same place as the existing ones, so it's an easy swap.
4. DCI coverage for the 5 is not known yet but will not be less than last years entry model.
5. An upgrade to 2.1 will likely be impossible, due to comlatibility issues.
As other companies on the show, they had no idea as to when the chip will be available nor compatibility with Dolby Vision and HDR10+.
JVC received me with open arms and even insisted on a selfie with the crazy guy from Israel who makes a habit of flying every year,just to take a look at their projectors, they were indeed very nice and welcoming.
I did take a hold of the remote trying to find out the MPC setting and they where on 5/2/ and 0 being the NR.
We did re-focus the unit per my request.
I sat through 2 Demos and I must say that something has clearly changed from the Demo on Friday, in terms of Noise and image stability.
I was very please with the latter and the absence of the former. I did however see Banding once more and hopefully it will be ironed out.
The DI was not working and the Iris was on -1.
Contrast was not bad to say the least, and in fact coming from the X9500, I couldn't say I saw a problem.
Brightness seemed to be OK, but then again it's a very big screen, so in my case with a smaller screen and an HP screen it will look totally different.
Sharpness and detail looked very impressive and not over processed, looked very natural to my eyes.
We did look at 1080p stuff and again, to my surprise, there was much much less noise.
Overall this was a MUCH better presentation than the one given on Friday.
I'm holding my final desicion about purchasing this until I can test it out thoroughly.
Thanks again for all the feedback Ran, much appreciated
Great news for the ANSI improvement for the three models, that could end up being more significant than native 4K for many of us and possibly more than compensate the drop in on/off (especially for those of us with a dedicated room coming from an rs5xx and considering the N7, the drop from an rs6xx to even an N9 is more significant) re overall PQ, not just low APL content. I can't wait to confirm this myself or get a confirmation from someone I trust.
Glad they implemented this slider for large/small screens. For those familiar with custom curves, this is similar to an adjustment for diffuse white / brightness factor. You can have the same values for hard clip, soft clip to adjust the highlights curve at the top end and the contrast according to HDR10 static metadata, but changing diffuse white / brightness factor is what makes the biggest difference regarding how bright the picture looks overall. Of course, the brightest the picture, the less headroom for the highlights, at least with BT2390. So if you go too far in one direction, you likely crush highlights, and if you go too far in the other, you likely crush near black. That's the downside of static metadata / processing for HDR.
What might help JVC vs custom curves is that they probably deviate from ST2390 in the low end to adjust dark gamma and bring out shadow detail, hopefully more than the default BT2390 curve but less than the black compensation option for BT2390 (that makes near black look a bit too grey to my taste, at least in a dedicated room). This could be nice for the darkest / poorly mastered titles.
Sounds like the JVC auto tone mapping is going to be a very significant improvement over the current implementation, and possibly even over well-designed custom curves tailored to a specific setup (i.e. not "generic" custom curves made by someone else, including myself), especially in the low end if they do a good job. I'm hoping that their implementation uses internally more controls than the dark gamma / picture tone / bright gamma shown in their demo (hopefully for simplification), in which case the picture might look good but it won't be as accurate as it could be with a few well-designed custom curves.
I'm looking forward to get a chance to evaluate the N7 or read objective data and detailed measurements from a reliable source.
