I a/b scenes with my oppo 203 in DV with the ub820 and the oppo does retain those bright details so i have been using the oppo for DV and ub820 for hdr-10 movies. This is on my c8 oled which is calibrated by gregg from lionav.
Thank you so very very very much for testing this out and responding! Especially grateful I have the C8 as well. I wonder how the hdr optimizer on the 820 compares with the oppo 203 when playing DV content? I’m hoping Panasonic is aware of this issue...?

he seems to be saying that due to some issue with the 820's Netflix app, there is no way to tell exactly which color format the 820 is outputting.

This is now certainly clear. As puzzling as that is (Panasonic has already done the heavy lifting with their superb tone mapping and optimizer to do this with discs) I would be happy to get streaming with these features working with HDR/BT2020.

Many others have said the same, and believe me, I would love to be able to use this player to stream and tone map HDR to my RS500 using their Optimizer. I can't seem to get it to work, and there seems to be much conflicting information over which settings to use, or if it's even possible.

All my testing has been done with a cable straight from 820 to JVC to remove all other variables. My first problem of no streaming HDR at all was solved by claw's instructions to set 4:4:4 for Netflix, He says 4:2:0 works for him with Amazon. It did not work for me. I need to set 4:4:4 to receive HDR from either of those apps. That gets me HDR/BT2020 with which I can use the tone mapping and Optimizer. I need only to manually switch out of gamma D. Not a big deal. But - with my viewing this so far, the projector keeps switching itself back into gamma D every few minutes. I've asked if this is normal, of if there is something I can set to avoid it. No comments regarding this issue so far, but obviously this is untenable.

The last remaining issue is claw's explanation (as I understood it) that we really can't tell what color gamut is being output from the Netflix app.

I'm merely trying to get this thing to work the proper way with the right settings. If I can get it to work in any sort of practical way, I'll be delighted.

Respectfully

@claw appears to have indicated that he was unsure of the color format specifically when he enabled Network SDR to HDR conversion (as an attempt to achieve SDR BT2020?). IMO, he hasn't stated that this ambiguity is applicable when that feature is disabled and output is set to HDR. I haven't seen any posting that suggests that streaming HDR is anything other than HDR10 BT2020 when the UB820/9000 is configured to output (plain vanilla) HDR. I'd truly appreciate it if you could point me to any relevant post that is at odds with that assertion. Thanks.

Sorry if I mistook that statement to suggest that you were already using an HDFury device. The only reason that I'm aware of to use HDFury (etc.) with the RS500 is to allow the DI to be operative with HDR content or to modify the EDID to send SDR BT2020 (and avoid any HDR issues). I was using the HDFury Integral specifically for that purpose before I upgraded from the RS500 to the NX7. That HDFury device is no longer part of my video chain.

Rereading his earlier posts, it’s quite possible you are correct - that this is only a problem when attempting SDR 2020. Perhaps he will confirm.

If so, that leaves only me one problem - the JVC switching back to gamma D on its own every few minutes. I wish I could find a work around for that.

Thank you for your help.

Couldn't you simply create a custom curve using one from Manni01 or Javs (etc.) that would possibly alleviate the Gamma D switching problem? I'm almost certain that there are multiple older posts on the RS500 owners' thread that would help you accomplish that. BTW, the NX7 has the ability to select what Gamma curve (User mode) you want as default when the HDR flag is present. I don't remember if that capability exists for the RS500, since I never accessed it. That might provide a work around if it's available.

You will have to use an HD Fury (or equivalent) to prevent the JVC from switching to Gamma D.

As I understand his problem, it's related to his RS500 spontaneously switching back to Gamma D intermittently while watching programming. Chad B. installed a custom curve on my RS500 when he did the calibration. Although it was necessary to switch from the Gamma D default to his curve, I don't remember ever experiencing an episode when I lost that curve during viewing. Why would he need an external device to maintain a curve other than Gamma D?

Pip reported that the projector switches to Gamma D every few minutes, which makes it impractical to manually switch back to a custom gamma and hence my suggestion for HD Fury.

The 2015 JVC projectors would switch the gamma to Gamma D on detection of HDR, regardless of the Picture Mode. The later models would switch the Picture Mode and hence will not exhibit the same behaviour.

EDIT: Since the UB820 HDR settings are highly customizable, one could leave the projector in Gamma D and adjust the UB820 settings to compensate.

I don't know why the JVC would keep switching to Gamma D during content playback. I would understand that it could when stopping playback of one Netflix title and starting playback of another, since the signal changes when the Netflix menus are up. HDR input triggers Gamma D... SDR menus do nothing... HDR then triggers Gamma D again.

Also, any video dropouts caused by HDMI cables would trigger Gamma D after HDMI resync.

I don't know about the UB820, but with the ATV4K playing HDR (labelled as Dolby Vision) on Netflix that is a known issue.

Can the 820 play 4k mkv files with Atmos now? also can you plug in an external USB drive to play them off of?

Yes, Netflix in HDR output mode works with the Optimizer. If you have an HDFury device you can verify that the Optimizer has modified the metadata values. If you set the HDR Display Type in the UB820 to Projector (500 nits), the Optimizer will tone map and modify MaxDML and MaxCLL to 500. The result looks very good with a custom Arve curve even if you haven't created a 500 nit curve and use a 1000 nit curve instead. The same results are obtained from Amazon.


Netflix in SDR/BT2020 output mode is the problem. Just setting the UB820 to SDR/BT2020 mode causes Netflix to not display the HDR badge on content that is HDR. Then when I play a known HDR title, I get 4K60 SDR REC709 reported by my HDfury.

A workaround to get SDR BT2020 is to turn on SDR/HDR Network Conversion in the UB820. But as I mentioned before, I don't know what the player is doing in this case. The SDR/HDR conversion converts all Netflix SDR, even the menus, to HDR. But what is the player actually doing with Netflix?

- HDR > SDR BT2020
- SDR REC709 > HDR BT2020 > SDR BT2020

Because I don't know which conversion is being performed to get SDR BT2020 with the workaround (I fear the worst case since the HDR Badge is still not displayed), I watch Netflix in HDR with the Optimizer turned on instead.

Regarding Gamma D, the only way to absolutely resolve it is to get an HDfury device that will disable the bit that triggers the JVC to switch to Gamma D. The HDfury will also prevent the JVC from disabling the Dynamic Iris when it sees HDR.

I compared Dv oppo vs hdr-10 (optimizer) and the oppo with DV has more color depth. The optimizer i only see a difference on high nit movies (4000 nits or higher) and no difference on 1000 nit movies. If you put in a 1000 nit movie and toggle the optimizer you will see no difference but if you put in a 4000 or higher nit movie (pan, batman v. superman etc.) you will see a big difference since it tone maps it down to the 1000 nit. So it makes sense that with 1000 nit movies you see no difference because with high nit movies it tone maps it down to 1000 nits where those 1000 nit movies are already. Panasonic stated there is no issue on their side with the DV bright highlights and it's with Dolby's side so i think it will be a long time before either company does anything but i could be wrong. Still love the ub820 for hdr-10/ regular BR and my oppo for DV/region free playback on blu rays etc.

Do you really think there are 820 settings which could overcome Gamma D? BTW: I have tried your EZ "in projector" Gamma D adjustments - a huge improvement over stock Gamma D, but IMHO 4K SDR (from the ATV) seems more accurate to me.

Thanks so much for your help.

Do you remember that you never lost your chosen gamma with Netflix from the 820 to the RS500? I'm wondering if the automatic switching back to Gamma D midstream is something I have set wrong, or it's something that happens no matter what - as with Netflix DV (not HDR10) titles with the ATV (the known issue Dominic noted).

I'll try cross posting this question in the projector threads. Maybe someone knows.

Thanks for your help.

I purchased the UB820 after I received the NX7. I was previously using the Panasonic UB900 with the RS500, so I can't speak to that specific device chain (UB820 -> RS500). Regarding HDR on the RS500, I can't remember ever losing the custom gamma curve (once selected) to Gamma D other than when there was an intermediate SDR source. As I recall, subsequently choosing a new HDR feed (after an SDR source) would default to Gamma D until I re-selected Chad's custom curve.

Is your UB820 outputting HDR2020 or SDR2020?

4K SDR from the ATV is just “plain” SDR, no BT.2020 and no specular highlights.

Hi. I bought this player today and am very pleased. But I'm having a weird issue with Dolby vision content.

On Black Panther, sometimes when a scene cuts to another shot, there is a quick bright flash as if the image brightens for a millisecond then goes back to normal.

But this did not seem to happen on Pacific Rim Uprising (another DV title) or Fast Five (HDR 10).

Any clue as to what could be causing this and how to fix it?

FYI, when I switch the player to forced HDR 10, this problem doesn't happen. But DV looks better to my eyes so I'd rather keep it. If anyone has insight into this problems I'd appreciate it.

I compared Dv oppo vs hdr-10 (optimizer) and the oppo with DV has more color depth. The optimizer i only see a difference on high nit movies (4000 nits or higher) and no difference on 1000 nit movies. If you put in a 1000 nit movie and toggle the optimizer you will see no difference but if you put in a 4000 or higher nit movie (pan, batman v. superman etc.) you will see a big difference since it tone maps it down to the 1000 nit. So it makes sense that with 1000 nit movies you see no difference because with high nit movies it tone maps it down to 1000 nits where those 1000 nit movies are already. Panasonic stated there is no issue on their side with the DV bright highlights and it's with Dolby's side so i think it will be a long time before either company does anything but i could be wrong. Still love the ub820 for hdr-10/ regular BR and my oppo for DV/region free playback on blu rays etc.
Wow, I most definitely did not expect you to do all of this! So greatly appreciated! That absolutely makes perfect sense. Are the majority of UHD releases 1,000 nit or more towards the 4,000? Ah, yeah, if it’s the blame game there definitely won’t be a fix coming. It kind of sucks I know it’s blowing out the highlights as I’m a sucker for details.

Last question, are you using Cinema or Cinema Home for DV content, if you don’t mind me asking? Anyways, thank you again so much for all of your effort in testing! Was a very nice surprise and completely unexpected, very greatly appreciated!

HDR2020. Do you think it's possible to significantly improve Gamma D with 820 Optimizer settings?

Thanks,

Gamma D sucks and you need to figure out what the real issue is (you should eventually at least load a premade curve but this is not the time since it isn’t the problem)

You are the only person I have heard having Gamma D issues on the 820. In fact, that was one of the reasons I bought one and I sold my HD Fury shortly afterward. I wonder why this is happening, it would be quite ironic if it was indeed an HDMI cable issue.

You said earlier your cable couldn’t do 4:4:4 so perhaps that’s an indication it is flaky with full bandwidth signals? I exclusively recommend this cable and I really wouldn’t screw around in this area. As soon as I went 4K my old “4K compatible” cable started causing issues. I replaced ALL my HDMI cables with the ones I recommended and haven’t had a single issue since. At least they are cheap.

Thanks. I posted later that I swapped in an 18GBS cable which does pass 4:4:4. My Gamma D issue is only with Netflix. Netflix (on the 820) will only output 2020 with HDR. With your settings for discs, the 820 is set to SDR2020, hence never even entering Gamma D. I believe this may be why you never saw Gamma D, but please correct me if you did stream Netflix HDR trouble free, so I can learn how you did it.

As Dominic said, the JVC switching back into Gamma D midstream is a known issue with ATV Netflix - but only with DV titles.

SDR2020 is exactly why I never saw Gamma D and is the reason I bought the 820. I have never used 4K Netflix which is why I’ve stayed mostly quiet on this topic. The ATV issue is well known in the JVC threads.

For the record though, I still only recommend real Premium Certified HDMI cables. This may or may not be your issue, I did not know you replaced your cable, hopefully it was with the cable I recommended or at least one that actually says “Premium Certified”.
