Now because of all this something I also want to compare is the strip metadata from the HD fury, I did not use this before but I get a funny feeling that this will give the same results.
I know a lot of people use this but I can't remember seeing a post where someone actually did measure what is being displayed on screen, let alone compare it with actual HDR/BT2020 on two projectors side by side.
Like I mentioned in the video, depending on the content it is sometimes very hard to see the difference, and especially if you can't compare without seeing the two colors next to each other.
I can do a test here with two JVC projectors side by side, one with actual HDR/BT2020 and the other with strip metadata or Oppo tone mapping.
I am beginning to think that the problem is not actually with the Oppo tone mapping itself, I am thinking that something in the communication between the player and projector is causing the projector to not display the actual BT2020.
Again, I am open to any suggestions that might prove the opposite but till now I have not seen anything that can show me that someone is actually getting the SDR/BT2020 on his projector.
I would be most happy if I can see someone that has gotten this to work, I can make mistakes and especially with these things it can happen before you know it.
That is the reason why I made the video so you can see what is going on, what settings I use and what the results are.
Like also mentioned, taking pictures is not a good way to prove this as I have done it and it is not possible to see, unless someone has a very good camera that can capture it.
The video camera I used to make the video is a pro broadcast camera (but a 1080P REC709) and even there what you see is a lot less then what I actually see on screen.
Thanks for taking the time to investigate this and post your findings.
I've been recently re-thinking all my efforts (and equipment purchases, experiments, troubleshooting time, forum time, bulb time, etc...) to get HDR-->SDR / bt2020 video to my JVC RS500.
Is it really worth it all? Apparently, it is so difficult to tell if the HDR->SDR bt2020 conversion is actually bt2020 that experiments and cameras are warranted to see if it is actually coming through as expected.
Maybe an interesting test / experiment - with video or photos as you've done - would be to just let a 4K movie disc play without any HDR, as r.709, into the PJ, and compare that to the results using the HDR-->SDR bt2020 output of same. Look for the notable increase in image quality there, and also note where the "old" way of doing it - no HDR at all - might actually look better.
It seems to me that HDR possibly came about in part because all of a sudden many displays could be much brighter than they ever were before (LCD sets, anyway, and I guess OLED to some extent also) and HDR was a great concept to utilize this newfound dynamic range (at least at the bright end).
Most PJs IMO though don't have even close to the brightness that gave HDR its start, and the "Old" SDR / r.709 standard worked pretty well for older / dimmer displays. Most PJs are set in dark rooms as well, and the eye-searing nit levels of those LCDs would likely be too much in that case, yet the blacks would still be sub standard (not withstanding the better local dimming and OLEDs etc...).
I'm all for "better color", if the bt2020 space is really delivering that much of an improvement on its own, with the HDR being converted back down to SDR (with the likely artifacts that must involve), but I'm wondering if we are really getting this palpable improvement onto the screen, after jumping through all the hoops required to make all this work.
I like the idea of having flexibility, and the 203 certainly allows for that, and It's pretty cool that you can use it's VP on an HDMI input (for streaming, especially).
So I'm a fan of being able to do things a number of ways, but I'm circling back around and considering re-thinking just playing discs / streams with the standards they were mastered for in place, using the standard settings available on the player or PJ (ie turning HDR "Off" if you want SDR, and not worrying about the color space etc... Settings I guess any 4K disc player or streamer likely has already.)
I'm sure it's likely that the disc player, outputting 4K as SDR is likely already doing something "non standard", and maybe with Vudu HDR streams too, played back on a Roku or Shield into a non HDR enabled display.
I just don't know - but maybe screen shots of actual Movie material displayed on a PJ showing the benefits of doing the HDR-->SDR bt2020 thing -vs- just leaving HDR "Off" would be useful?
Just my .02 anyway.
