Long press (hold down for a couple of seconds) the HDR button and youll see the HDR menu that lets you turn on/off the optimizer, adjust the slider, brightness, black and white levels, etc. I think you can also access the menu with the Options button.

I think you have to be playing 4k hdr material to access it.

You just have to make sure your pj is configured properly (gamma 2.4/d65/bt2020)
But will the Tone Mapping work for streaming HDR? I never buy DVDs and Netflix does not rent 4k DVDs. I have Planet Earth II which looks great without Tone Mapping on my OPPO but that and the Oceanic version are the only thing worth owning IMHO. So I was hoping to get HDR content from Netflix/Amazon streaming.

I was not able to get it to work with streaming 4k HDR from Amazon but will fiddle with it some more. I can put in a BR 4K to bring it up but not sure any of the settings will ofer over to streaming...

Sorry, i dont know as much about the streaming as I use an apple 4k tv.

I *think* SDR 2020 works with amazon app but not on netflix. So you might just want to keep it on HDR2020 with optimizer on in that case. Ive found the interface slow and buggy when Ive tried to use the streaming apps and could never get atmos to work like others have, so I just gave up on the streaming stuff and use my apple 4k tv instead.

No Netflix ATMOS for me from the 820, only from the ATV.

Curious why some do and some don't. I'm gonna assume that those that do get Atmos are indeed using a 4K capable display. I'm on a 1080p projector with the 4K Netflix subscription but no joy on HDR or Atmos titles.

I dont know, it drove me crazy for a while, but the apple 4k tv works so well, Im fine using it.

I figured it was some combination of avr that doesnt recognize the form of atmos it outputs. Even if I ever figure it out, Id probably still use the apple 4k tv because the interface is so much smoother.

Obviously there is some combination of HDCP flag or signaling or something that is activating Atmos with those owners of the UB820 that get Atmos with streaming media.

However, one phone call to Netflix, Panasonic, or Amazon CS will confirm that **OFFICIALLY** the player doesn't support it; and MOST haven't been able to achieve it.

I finally bought a 4K Apple TV and couldn't be happier with the PQ and the Atmos support. Even if Atmos worked for me with Prime Video, the quality of picture sucked...with its stuttering, glitchy playback, etc....and I have gigabit internet with an ethernet connection to the 820.
I have the ATV for the same reasons as you, but for some reason some Prime shows that indicate 5.1 are recognized on my Anthem AVR as 2.0 while others indicate Multi-PCM (and certainly no Atmos on Jack Ryan). Plus, the Prime picture is noticeably darker (info indicates HDR but HDR button on remote does nothing).

Looks like 3 different players to get what I want. Crazy.

D65 is the preferred (my preferred?) color temp on my sony, so theres probably an equivelant one on your jvc (might be called 6500K). This would be the same thing you use on regular blu-rays


Good evening all. OK, so I’m an 820 and RS400 owner. I’d like to confirm I’ve got the best settings for my 820 to read the metadata for each disc, and then set tone mapping based on the data to 2020/SDR.

820-
2020/SDR output
Projector Luminance
HDR Optimizer On
HDR Slider +2
4K/60 at 4:4:4 On
HDR10 (On or Off?) Mine is set to On

JVC RS400:
BT2020 WCG
Custom Gamma 2.4

Also, anyone know for sure if Netflix is bring output in 2020/SDR for HDR material as well? If material is streamed at 4K SDR, should I use a REC709 Color Gamut mode on the JVC?

I’ve read through a lot of posts here, and in the 9000 forum (which has just added to my confusion) so just want to make sure I’ve got this all right.

This almost certainly seems like a setup issue. My Anthem/ATV 4K was behaving like prior to adjusting the settings in the ATV. When seeing the 5.1 logo the Anthem should say Multi-PCM on the on-screen display. Jack Ryan should 100% be Dolby Atmos as Apple TV 4K is on the approved list for Dolby Atmos with Prime Video and Netflix.

Are you using an AVM60 AVR?

Not to mention that even IF the UB820 streamed Netflix and Prime Video flawlessly, it doesn't have a search function that allows you to type like you can with the Apple TV remote app on your phone. The ATV makes searching for streaming content fast.

Anyone else having their "Purchased" titles show up as 480p in Youtube? Any other 4K content on YT works great, just not able to get my purchased titles in any higher resolution than 480p.

The real question might be does anyone else purchase 4K titles on YouTube? I didn't even know that was a thing.

Well I'm sure they do...but in my case, these are purchased titles that came into my Google Play account via Movies Anywhere.

Keep in mind, I can watch them correctly on my Nvidia Shield through Youtube, just not the Youtube app on this player.

Hey guys,

Moving my much loved Oppo 203 to another room and I have put in the Panny 820. Build quality which I am sure has been discussed is nothing like the Oppo. Picture right out of the box is good, have not had a chance to make setting adjustments.

My question is the disc drawer seems very loud, like a motor sound. Kind of like a motor going bad sound. Just seems louder then maybe it should be. My Oppo you didn't even hear when it went in and out. Just wondering if that's the way this one is. If others are quiet I am thinking of bring mine back for an exchange to BB.

Would like some others opinions please and thanks.

Brian

So maybe this is of the norm for them. Would love to hear from others as well. Not sure if I should go for an exchange or not.

With the UB820 set to output HDR, not SDR/BT2020; the HDR Optimizer works with both Netflix and Amazon HDR titles. If you have any device that can show the incoming metadata you would see that the HDR Optimizer has altered the original metadata to new values that reflect the HDR Display Type setting. You just have to make adjustments to the Optimizer while playing a disc. They carry over to streaming.

Yep that's what I updated to, from I think 1.12. I have been using the player weekly so assumed it was a new update. Am I way off?

Thanks Man.

Answered my own question. Have to hold down HDR Setting button.

Have optimizer on and dynamic range and brightness at +2 for the 2020/SDR output to the RS400.

Thanks again. Edited the post after I figured it out.

Yes, I could run a 4k HDR disk and make the Optimizer adjustments but I found that if I have the output set to 4:4:4 the HDR button becomes active. The results so far are not encouraging. Once I run it that way the Amazon HDR (I Use Mrs. Maisel for my testing) becomes washed out and I have to completely redo the settings to bring it back to what the OPPO 203 will give me through A4K. I have not yet finished twiddling but still looking for an advantage with the Panny.

BTW, I do not get the wash out effect with 4:2:0 nor do I get HDR output.

I frequently see 1080p on the information screen even as I am in HDR and the JVC Projector shows 4k/60 on info.

I don't have a lot of 4K HDR disks. Earth II looks so damn good on the OPPO 203 I am not sure Tone Mapping will improve but I can try it.

I have not yet finished twiddling but still looking for an advantage with the Panny.

BTW, I do not get the wash out effect with 4:2:0 nor do I get HDR output.

Any chance your RS640 is not set to an HDR picture mode? That would explain the washed out picture.

Below is a copy of some posts I copied so I could remember from months back. Hope it is useful

From Kris Deering "Alright, here is the deal. I think a lot of people on these boards aren't 100% in their understanding of HDR and how it pertains to projectors. Therefore, the following comments APPLY TO PROJECTOR IMPLEMENTATION ONLY!!!

First, THERE IS NO SUCH THING AS SDR vs HDR. The reason you see this moniker is to make it easier to understand the base calibration that should be performed. There is no such thing as taking HDR and making it SDR. There is only tone mapping. Because the projector can only reach a low nit level you have three options: the projector tone maps (HDR GAMMA MODE), a custom tone map (ARVE) or the player tone maps (SDR2020). ALL of these solutions are trying to accomplish the same thing, taking a HDR signal and making it work with a low light display.

Projector tone maps are all based on best guess/research by the company. There is no standard. Arve tool is similar, though I believe he may be taking into account the suggestions made for tone mapping in BT2390. But it is still doing the same thing, it just allows the end user to tailor the curve more to their MEASURED display max and allows choices for aggressiveness. But the Arve curve does some things wrong with color support/desaturation, which you can read up on in the MadVR thread. The SDR2020 is just another tone map that is generated by the player to a specified brightness level (set by the slider). You calibrate the projector to a known state (gamma 2.4) so that Panasonic (or whoever is doing it, Oppo did something similar) knows what the underlying gamma their tone map is being applied to. The UB820 changes the tone map dynamically based on the metadata read from the disc. The Arve curves are setup for specific circumstances (1000 nits, 1200 nits, 4000 nits) and the hope is these will be good enough for most images you watch (and they look quite good all things considered). The Panasonic actually changes its tone map on a title by title basis, so long as the title has different values to change to (MaxCLL levels that vary). This maximizes your light usage on a title by title basis, so long as the information on the disc is right. It also applies the proper color handling, unlike the Arve curves.

The only other option is what you mentioned above, using an Arve curve INSTEAD of the projector HDR mode and then sending a tone mapped HDR signal (HDR Optimizer ON and HDR). This would be applying the Optimizer on top of your Arve curve. The Optimizer would be working with the assumption of a 500 nit display base, but that is also changed with the slider.

I can't think of any reason to do that final option unless you had a projector that would not accept 2020 color unless it was actually seeing an HDR signal (I know this doesn't apply to either the Sony models I've tested or the JVCs). I would recommend using the SDR2020 mode in ALL usage cases that I'm aware of. This would (IMHO) give you the best tone mapping which would be adaptive to the content, have proper color handling, and can be adjusted "to taste" on the fly for content that may need additional tweaking.

Panasonic isn't telling me everything they do, that would be giving out their R&D work for others to use. But for SDR2020 I imagine they are applying desaturation based on a 1000 nit tone map (Optimizer OFF) and where the slider is for display max. With Optimizer ON, they would apply based on the tone map (which is based on either the MaxCLL or MaxDML) and where the slider is for your display.

And Erod--
It is important that you zero out all the settings on your projector beforehand to allow the tone mapping to go to work. In my case, I set up a Custom setting for SDR2020 with my JVC rs620 set to BT.2020, Custom 1 (D6500, and 2.4 gamma. Everything telse o 0.

Then, I upped the dynamic range slider to +6 to give the image some brightness, then I played with the black and white tone controls. They look good at 0, but I went ahead and set the white tone to +1 and the black tone to -1.

Kris about Optomizer
With output set to SDR - If you have HDR optimizer OFF, the player does a generic tone map with all content tone mapped at 1000 nits (because most content falls around 1000 nits max) and it assumes your display is around 350 nits (based on not changing the slider). This will actually work well with the majority of content because again, the majority of content is 1000 nits and the majority of SDR type displays work well with 350 nits. If you turn the optimizer ON, the only difference now is the player intelligently tone maps based on the discs metadata, so no more just always tone mapping to 1000 nits. This will optimize on a per disc basis for titles that have information different than just 1000 nits (think Sony, Warner, Lionsgate). Now the tone map will be based on the specific title to the peak value you set for your display. So if you have a title that is 1000 nits (Fox and Disney), it will look exactly the same as Optimizer off, but if you have titles with MaxCLL that is a lot higher or lower, it will optimize the tone map for those titles. Obviously the farther away from 1000 nits, the more optimization occurs. So YMMV on a title by title basis. "

A very useful summary. Thanks for posting. For those of us with Epson Home/Pro Cinema projectors then, applying the SDR2020 setting in the 820, then my understanding of settings for the Epson would be setting the dynamic range to SDR, use Digital Cinema, gamma -2, and most other settings at default or alternatively use Harpervision or its derivatives that are also based on SDR. Use the 820's video options to tune the picture to suit.

My small rant is, what an unnecessarily complicated set of variables HDR and rec2020 have wrought.

1.47 is the most recent update as of 9/2018, so you are current with that update installed.

Some of us are curious if the 820 might receive another update to add some of the UB9000 features we have been recently discussing. Probably not, but I have my fingers crossed.

Yep, that's pretty much what I've been saying.

I only need to up the dynamic range slider to +2 for a great picture, but I like to go to +5 so I can incorporate the DI at -5 on Auto 2. I've settled on 0 for white tone and +1 for black tone. Different movies respond differently to those settings, but that seems like a nice neutral because I don't like making changes every time.

On my rs620, I use a 2020 file that Chad made for me for SDR, then I use Custom 3 gamma because it's the only one "zeroed" out. Chad calibrated the first two, and they make HDR content look too warm on SDR2020. However, those two calibrations look great for rec709 material.

There are scenes, especially outdoor scenes, that actually look best with Chad's HDR settings and imported curves (Jumanji comes to mind). They look PHENOMENAL. But then those settings struggle with detail in other conditions, especially for darker scenes, and at other times appear overly saturated. That's why the tone mapping is so great in the SDR2020 mode because it gets through all the different tests in a much more consistent fashion. Much more set it and forget it.

Dynamic tone mapping, one day, is what will really help projectors shine. If Panasonic can figure that out, they're going to sell a millions of those players.
