Unlike the Netflix App which seems to recognize the SDR/BT2020 or SDR/BT709 output option and refuses to output HDR unless the HDR output option is set.

I have no idea why Netflix would do this. I still consider it to be a bug. It should show the HDR label and output HDR solely on the condition that your display device (and any other device in the chain) supports HDR10 and HDCP 2.2. Why should Netflix care that the UB820 is going to perform tone mapping from HDR10 to SDR BT2020 or to SDR BT709, and not allow it to happen by sending SDR REC709 instead of HDR?
Perfect!!!!

Here are the screen shots from The Expanse S4:E1 0:24. To be honest, compared with the "normal" SDR from ATV4K I don't find the SDR2020 version any more HDR-like (brighter highlights, higher contrast). The the actual HDR version is also attached as reference. Personally I see no advantage in using SDR2020 in this case.

I’m not sure why the UB820 will still send out the HDR metadata, when the output has already been tone mapped to SDR.

Which VPR is it? Does it not react tho the HDR signal by switching to ST.2084 (which would be wrong in this case)?

Yes, it has always done that. Also strange is that if you check the metadata string it sends a EOTF value of 1 instead of EOTF 0 for SDR or EOTF 2 for PQ. I asked HDfury long ago to change the JVC Macros so that EOTF 1 triggered the SDR BT2020 Macro instead of a HDR macro that it was triggering.

Is there a fix for Netflix audio sync? All my sources are correct on my Denon 3500 and on my 820, discs, prime and network media are all in sync, ONLY Netflix is off. Not sure how to fix this.

The VPR react to the HDR signal if I set the player in HDR 2020 ... Not in SDR 2020, but still recognize the signal as HDR. In fact, there is a clear difference between the photos...

I don't know if the RS540 is different from the RS500 that I have that will switch to HDR mode if it gets a HDR signal, but does not switch out of it if it gets an SDR signal. I have to manually change to SDR picture mode. This normal for the RS500.

Same behavior for RS 540. But with Prime Video and Youtube as I said if I set in SDR 2020 it recognizes an HDR signal, with BT 2020 color space and related HDR metadata without however automatically going into HDR mode, which happens if HDR 2020 is set by player. With Netflix it recognizes only an SDR 709 signal. At this point for Netflix I will set up HDR 2020 and use the tone mapping of the HDR optimizer.

This is normal. In SDR/BT2020 mode, the UB820 is including the original metadata of the HDR source. But the EOTF field in the metadata is 1, while the EOTF value for HDR is 2. The JVC projectors will not switch to HDR mode unless the metadata in the signal is EOTF2 (PQ).

For SDR 2020 you don't want the JVC to go into HDR mode. You want to use a custom user mode with BT.2020 color profile and Gamma 2.4.


With Netflix it recognizes only an SDR 709 signal. At this point for Netflix I will set up HDR 2020 and use the tone mapping of the HDR optimizer.

This is a known issue where the Netflix App refuses to output the HDR version of source content when the UB820 is set to SDR/BT2020. It treats this case the same as it would if the connected display is not HDR capable. Netflix sends the SDR REC709 version of the source, in which case the HDR Optimizer has nothing to do since it only works with HDR10 content.

yes, with ub820 you have two output options for HDR tonemap and HDR-SDR tonemap: you can tell it SDR bt2020; and the tone map will apply based on your display device type selection; and you will get a really good SDR bt2020 image with no HDR in the signal output. If you tell it HDR output; it will still tonemap based on your selection style; with HDR in the signal. up to you what you want based on the HDR capabilities of your display; nits, brightness, etc.

Possible Problem passing correct audio formats

I think I have a problem with my new Pioneer SC-LX904 receiver processing the correct audio format from my Panasonic UB820 but I am not sure. My system is 7.1.2. What I think is the problem is happening whether it’s a 4K Dolby Atmos or DTS:X disc. This is what is happening:

4K Saving Private Ryan- Dolby Atmos: Player shows it is playing Dolby TrueHD 7.1. Receiver shows Dolby Audio-DD 5.1 input and 7.1.2 Dolby Audio-Surr output. I think the receiver should be getting Dolby TrueHD 7.1 input and Dolby Atmos 7.1.2 output. Similar scenario with DTS:X.

4K Gladiator -DTS:X: Player shows it is playing DTS-HD Master 7.1. Receiver shows DTS 5.1 input and 7.1.2 DTS Neural:X output. I think the receiver should be getting DTS-HD Master 7.1 input and DTS:X 7.1.2 output.

My understanding is that Dolby Surround and DTS Neural:X are formats that are employed when true Dolby Atmos and/or DTS:X are not available. The receiver is supposed to support both of the higher. Any advice or suggestions would be greatly appreciated. Thanks!

Dmk300 I too have a Pioneer receiver although not the same model of yours hooked up to my UB820. My remote has a "SURR" button near the bottom. I've had to pushed that several times so the output is what it's supposed to be for different input formats. I see on your remote the "SURR" button is near the center of your remote between "AURO DIRECT" and "STEREO" buttons.

Receiver: Pioneer Atmos VSX-LX102, 5.1.2 Setup
Source: Panasonic DB-UB820 4K Player
Display: Sony XBR-85X900F LCD 4K
Speakers: Klipsch Lt & Rt Front RP-280FA Atmos, Center RP-45OCA, Lt & Rt Surrounds RP-250S, Subwoofer R-112SW

It does sound like a receiver issue. So long as your player is set to bitstream out (which it must be as if it wasn't you'd see LPCM 7.1 etc) but the fact that your receiver is showing the contained DD 5.1 etc means that the receiver is reverting to the contained lossy track (eg A Dolby TrueHD Atmos track contains an embedded DD AC3 5.1 lossy signal that a receiver uses if it is unable to decode the TrueHD Atmos

Thanks for the suggestion! I tried it and when I cycle through, it never gives me Dolby Atmos or DTS:X respectively. It only shows Dolby auto-surr or dts neural:x.

Thanks much for the feedback. This is exactly what I have been suspecting, but didn’t know the specifics. Very helpful!

Can you also check on the player when you bring up the Info page during playback? You said the player shows TrueHD Atmos, but the player isn't aware of Atmos content, and the Info screen will just show the underlying TrueHD 7.1. The only place on the player side you might see TrueHD Atmos is on the disc menu. But if for some reason the info screen is showing DD 5.1 it is the player or disc.

One thing to check with is many WArner discs (even up to the Matrix UHD) DEFAULT the audio to the lossy. So The Matrix has DTS:X MA audio, but if you just put the disc in and play, it will play the lossy DD 5.1 track...

I have made it a habit to ALWAYS check the audio menu on the disc and select the appropriate one.

Unfortunately, I sometimes forget, and don't notice until I look at the receiver.

A recent funny situation happened last weekend, I was watching Terminator (the original), and noticed it was playing DD 5.1. I thought what on earth, and bought up the menu, and noticed the only other track was PCM 5.1. Then I realized I grabbed the wrong disc, the original BR release, not the new remastered one... So I swapped discs. Oh gee what a difference in image quality too. Unbelievable.

Good suggestions. The player only shows 7.1, either Dolby truehd or dts-hd mstr. Neither indicates “Atmos” or “dts:x”

The Dolby Atmos disc is dreamworks/paramount and the dts is dreamworks/universal.

Good suggestions. I checked and all those settings are set correctly. The receiver should be processing the audio correctly. Very perplexing.

OK, then the player is definitely behaving correctly.

I wonder what is up then on the AVR? Very odd.

Does it possibly do something different if you don't have overhead speakers? How many speakers you have configured in the setup?

A recent funny situation happened last weekend, I was watching Terminator (the original), and noticed it was playing DD 5.1. I thought what on earth, and bought up the menu, and noticed the only other track was PCM 5.1. Then I realized I grabbed the wrong disc, the original BR release, not the new remastered one... So I swapped discs. Oh gee what a difference in image quality too. Unbelievable.
The improvements are truly impressive. Like going from vhs to dvd and mp3 to hi-res audio!

Is Secondary Audio turned off on the 820? If it is, I suggest you continue this in the Pioneer AVR thread.

It is. I have and so far, the opinion is something is going on with the receiver. Thanks much for your help and advice. I thought the player was working fine, I needed to rule it out as a cause of the problem.

Sure, but with Netflix I will now use the player set in HDR 2020 so the Netflix app will give me the content in HDR and I will do the tone mapping to the HDR optimizer of the player ... otherwise I can in no way have HDR content with Netflix

I just purchased Masciola’s HDR10 patterns and the Dolby Vision patterns, and put them both on a USB hard drive connected to the rear USB port. The HDR10 patterns played fine but DV ones just said “Cannot play this file”. I was able to play DV discs with no problem, so it doesn’t seem like a set up problem.

Has anyone been able to play DV from the USB input?
