Gotcha. I think the 900+Integral does an excellent job with SDR 2020.
...But the UHD standard was also delivered with actual specifications on how to do this conversion, unlike converting to SDR with 2020. ...
Here is some stuff to read about UHD HDR WCG calibration.http://files.spectracal.com/Documents/White%20Papers/HDR_Demystified.pdf
Kris should the new JVC models improve this in any way?
Not Kris, but the new JVC models really only have two changes over the current models - low latency ( " gaming " ) mode, and auto HDR plus HLG. But with numerous user mode settings, you can set one up for no HDR and having it map down to standard gamma and REC709 per Kris's suggestion.
Ah ok, so the new hdr mode doesn't help the projector correctly map hdr levels?And do I have to do a captcha every time I post in this forum? So far it's two for two...
Hey Everyone. Just thought I'd chime in with some thoughts and experiments I've been running the last few days. As all are more than aware of here HDR on projection is sort of a work in progress right now. I haven't had the chance to play with HDR with the newer Sony offerings since they've revamped with firmware, so most of these comments are based on my time with the JVC X750. Initially most were using JVC's recommended settings and then going from there using a fleeting amount of test patterns that are available to dial in a picture that looks good. The problem there is while it may look good, it is still a best guess approach at this point derived mainly from trial and error with other's settings or successes. The next step was converting the HDR output to a SDR output but retaining the WCG capacity of the video signal. This seems to work best with the Panasonic player at the moment, but even after many weeks of trial and error I still see issues with gamma, mild clipping and more with this solution. Since the WCG portion of the movie is mastered in relation to the HDR EOTF, I imagine we are still seeing an improper conversion down to SDR levels as you would have to take into account the change in color volume from the intended display luminance. Sure it can look good still, but I would almost argue that the same look could be obtained with standard Blu-ray by just using a wider color preset on the projector. Call me a video snob but I prefer accurate to intent images rather than images that just look good. So I decided to try something that no one ever seems to consider or try, telling the player NO for HDR and having it map down to standard gamma and REC709 color. This still preserves the resolution bump offered by UHD and the 10-bit video. But the UHD standard was also delivered with actual specifications on how to do this conversion, unlike converting to SDR with 2020. Using this method I get a proper conversion for both gamma and color to SDR, and can view the movie with a proper calibration. I have to say, so far I'm far more impressed with this as the image never has that "it looks great, but there are a few things that still look off". Like everyone else I am hoping that solutions will come that deliver an ACCURATE fold down to SDR with 2020 color, but it appears we are not there yet. I am also anxious to see what can be achieved with a Radiance Pro that tone maps HDR down to the projector's true output in what appears to be a much more intelligent fashion. Until then, I think I'm going to stick with this (other than continuing experimentation with the other options for testing purposes) for now and just sit back and enjoy.
