It sounds like you need to adjust your HDR settings and try again. Below is a link to settings for your particular set, with HDR settings near the bottom. Make sure you follow their directions to enable “enhanced” for your HDMI input.

If you already have done all these things, then I’m at a loss. While I haven’t watched Black Panther yet, every review I’ve read states it is an improvement over thr blu-Ray.

Do you leave the E7 tone mapping on? I'm a bit confused about whether the LG's tone mapping should be enabled with this player or not, and on an C8/E8 whether Dynamic Tone Mapping should be on or not.

I did, but my understanding from a post I read by Bob P is that the way LG implemented tone mapping on the "7" and "8" is not exactly the same. On the 7, the Panny tone mapping was considered complementary, on the 8 panels someone here had mentioned that LG mimicked what Panny had done with tone mapping and so it was kinda more of the same, so not as beneficial.

In that instance, I'd definitely use the eyeball test. Turn tone mapping on and off on both devices using the same scene from a movie mastered at 4000 to 10,000 and see what your eyes tell you.

I have adjusted the settings on the set as per there recommendations and have cheeked that I have the enhanced HDMI on and connected via HDMI 3.
Unfortunately it hasn't really made any difference. What are the recommended settings fo the ub820? the dolby vision logo appears in the corner of the screen when you start watching the 4k film. would then dv logo appear if the short HDMI cable that connects the player to the receiver was unsuitable. what i have noticed is when 24p out put is set to automatic it plays black panther at 4k 24hz but when its set to off it will play at 4k 60hz is this normal and should I keep it off.

Depends. The disk produces 24 Hz video. You want to avoid the famous 3:2 pulldown needed to convert 24Hz to 60. If your display device has a native 120 Hz refresh rate (NOT a "motion rate"), feed it 24 Hz, and there will be no pulldown.

If it's a native 60Hz device, I don't know whether the 820 or the display would do a better job of the 60 Hz conversion.

I wouldn't bet my life on these recommendations, but I think that they are correct.

Did you find a fix for this. I'm having the similar issues. Sometimes it'll even say something about limited bandwidth, which is ridiculous because I have 100mbps down and wired. Also, no issues playing Prime app on my xbox x.

Dolby Vision is its own animal. The HDR Optimizer is not used during dolby vision playback. And yes, Black Panther is a very dark movie.

I have an 820 paired up with a new JVC RS2000.

What are some initial steps to take on the 820 when setting up this combo?

I've also noticed on movies that (and this is just a guess) have new 4k scans (The Matrix, Transformers) - there is a lot of noise in the picture, especially in the sky. When I watch Infinity War though - looks amazing. Anything I can check on that?

I watched it again last night. I use SDR/BT2020 mode to my JVC projector. All I needed to do to get a more pleasing picture for this title was to adjust the Dynamic Range Conversion Adj. slider one click to the right. Then reverted the setting back to where it looks best for most other titles. The Conversion Adj. slider does not need to be a set-and-forget setting.

The only improvement i could get was to turn off the 4k/60Hz requirement on the settings for the player. This had the app send 1080p with HDR - Bt2020. The streaming was much better but not perfect (less buffering). Overall, it was about an 80% improvement. I did not see any difference in picture quality -- both were HDR and very nice.

I usually can watch something for about an hour before it starts to stutter and become unwatchable. Did a reset last night and new update. Will see today if it makes any difference. My ub900 was glitchy too. This might be my last panasonic.

I think the UB820 has an issue with apps. Using an Ignite tv system now to watch Netflix, and no issues with receiving HDR which was a problem through my UB820.

Sadly you may be right. I really like the ability to optmize hdr for streaming. I thought that was a really cool feature and did work well for me especially with Netflix shows like The Ozark. Interestingly enough, Netflix seems to be running well. I guess I'll be using my xbox x for Prime vids and ub820 for Netflix.

All ultra high speed cables are being used. I do get 4k 60 hz 3840x2160 60p HDR UHD using my Apple TV (second pic) waching Jack Ryan.

Here is my setup:

All new components. Denon X6500. Samsung Q7 and this panasonic player. All have HDR10 and are enabled where they can be.

Panny settings:

Resolution Auto
4k/60p 4:4:4
24p auto
Hdmi output mode video plus audio
Dolby vision off
Hdr 10 on
Deep color auto 12bit
Hdr/bt 20:20
Hdcp auto


On the tv:

Hdr plus enabled
Any net cec

Reciever

4k signal format enabled

All firmware has been updated on all devices and I have hard reset the Panny twice.
I have the same issue in the UK after updating firmware (unit is only 3 weeks old), I have contacted Panasonic.
Its a handshake issue, some UHD discs are fine, but most are not, eg, loaded A Star is Born, HDR banner pops up (LG E7), at the disc menu I choose play movie, then the HDR drops and its a washed out SDR image. I need to powercycle the Av Receiver or tv to sort it out. Power cycling player will just repeat the process.
Arrival was an odd one, choose play movie and the first production company remains in HDR, then the Paramount stars start to fly in and it drops HDR (LG only allow choice of SDR modes), again, quick AV receiver power cycle and the HDR flag comes back on.
It wasn't doing this before the 820 player firmware update, I have also tried the player reset options provided by Panasonic support and no joy, unfortunately can't roll the firmware back...
Both TV/receiver last had their firmware updated months ago.
Will chase Panny again tomorrow...

A few on UK AVForums have experienced similar issues with some having 3D issues...

I have an issue potentially associated with the 820, connected through a Denon 6300H to an epson 5040.

When I am playing around with settings I swap between the Disc or NetFlix playing, to the home screen to go to settings. This causes a handshake with the projector, which is normal.

Sometimes when I hit the button to go to the home screen on the player (so I can change settings), it looses the signal and my PJ shows "no signal". Hitting the play or Netflix button gets me back to my movie with no issues. I've tried changing inputs on the projector, which should grab another handshake and that does not cure it. I have a Ruprio HDMI cable and when playing content the full bandwidth I am sending makes it to the projector with no issues (so I am ruling out the cable).

Anyone have a similar issue?

I’m looking for opinions regarding leaving discs in the player. I generally tend to leave them in over night and then swap out another one to play the next evening. I of course know not to move the player with discs in it but otherwise looking for what others do. I recall reading awhile back for CD players it helps keep the dust out if you keep a disc in so wanted to know if others applied this as the best way to go for Blu Ray players as well. Also, looking to see if cinema or standard is used more by owners of this player with SDR blu rays? Thanks so much in advance to anyone who responds!

I routinely leave discs in (and always have) with no issues.

I do the same - leave the disc in until I change for another one. It’s rarely empty.

Question No sound out (ONLY when using Netflix app)

If I turn off Dolby Vision on the player, then I can access Netflix, and a picture is shown.

There shouldn’t be a problem with Dolby Vision, though, because Dolby Vision discs play fine. Only Netflix on the player has a problem.

Anyone else experiencing something like this, and any ideas what other troubleshooting to try?

Funnily enough, given the reply to your question suggesting lack of picture may be due to possibly having a 2016 LG OLED E6 - I have the opposite problem with a 2016 LG OLED but I think the TV immaterial.

Using the UB820 I no longer have sound when using Netflix app (connected to a NAD 758 and thence to the LG).

Playing a Bluray works faultlessly as indeed does the Youtube app.

Set up only a couple of days old and initially had erratic ARC/CEC issues between the NAD and the LG but found a workaround by disabling the standby mode on the NAD. HDMI ARC sound now stable and UB820 Netflix continued to work until this morning before strangely producing, now, picture only.


Interestingly this problem briefly reared up during the set up to the puzzlement of SSAV (store which sold and installed all gear) but disappeared on switching to a different source (live TV I believe) and then back to the Panasonic and Netflix.

As for the HDMI cables, entire system installed by Sevenoaks and worked to begin with (and the price of the cable suggests it certainly up to the task).


Speakers Radius 270 fron and 90 rear with a REL T70 sub but I do not believe the issue there.



The NAD now shows "PCM Stereo" on the display panel when Netflix app used on the Panasonic but of course no sound going through.


Any suggestions gratefully received...

Sometimes when I hit the button to go to the home screen on the player (so I can change settings), it looses the signal and my PJ shows "no signal". Hitting the play or Netflix button gets me back to my movie with no issues. I've tried changing inputs on the projector, which should grab another handshake and that does not cure it. I have a Ruprio HDMI cable and when playing content the full bandwidth I am sending makes it to the projector with no issues (so I am ruling out the cable).

Anyone have a similar issue?
I was playing around with the Denon Remote App and saw that "Auto Lip Sync" was turned on. I definitely don't remember turning that on and I don't think that is the default. Do these players (or the PJ) signal the receiver to turn that feature on?

Thx

I have a JVC RS2000 projector. I’m having a bit of trouble seemingly seeing a “noisy” picture.

It’s strange, I only really notice on faces and in the background/sky. Darker areas it doesn’t show up.

It also doesn’t show up in animation. It’s odd.

Take Ready Player One for instance. The race scene near the beginning, anything in the “Oasis” world looks great. When the IOI guys are getting into their “cars”’in the real world, it’s static or something. Really grainy.

I’m using the HDR/2020 setting on my 820 and the HDR10 setting on my JVC.

What could be causing this noise? Why do you use SDR/2020 for HDR content?

In SDR/BT2020 mode you set your display to a 2.4 gamma whether you have the Optimizer turned ON or OFF. In HDR mode you set your display to an HDR gamma whether you have the Optimizer turned ON or OFF since it sends HDR signal in both cases.



I have mentioned this before but here goes again.



In HDR output mode, the HDR Optimizer uses the HDR Display Type setting nit value as a tone mapping target. If you choose 500 nit Projector as Display Type, the Optimizer will tone map all bright content above 500 nits so that it falls under 500 nits. It will modify the HDR metadata that the display sees. If the original metadata was MaxDML=4000 and MaxCLL=800, it will modify them to MaxDML=500 and MaxCLL=500. If the metadata was 1000/300, it would modify the metadata to 500/300. The Optimizer is making it easier for your projector to complete the tone mapping of the HDR content. It doesn't have to be concerned with anything above 500 nit because there no longer is any.



In SDR/BT2020 output mode, the HDR Optimizer does not use the HDR Display Type setting. It uses the HDR metadata values to assist in performing a complete tone mapping of the HDR content to a 2.4 Gamma but preserving the BT2020 wide color gamut. The projector in this case does not do any HDR tone mapping since it has already been completed by the UB820.



I can't help you with the settings to use in your brand of projector as I have a JVC. The setting procedures for HDR/BT2020 vs SDR/BT2020 differ just like they do in different brands of HDR TVs.


This is all great information. Can you help with my post above at all? I’m using HDR2020 right now. You’re saying I should be using SDR2020?

What JVC projector do you have?

Hey all,


Thinking of getting the Panny 820 to replace my Sony x800 so I can have DV capability. However, I have a Sony x940e TV, which requires DV to be handled by the player. Does the Panny 820 work with the Sony x940e for Dolby Vision?



General question:
How is the DV quality? Is there still elevated black levels that plagued movies back when DV capability first rolled out in 2017?

I use SDR/BT2020 because I have a JVC RS500 and the result is better than any custom curve I have built so far. Kris Deering also recommended SDR/BT2020 for projectors. That recommendation may or may not change when he tests the new JVC lineup and auto tone mapping.

I have no idea what might be the cause of the noise you are experiencing.

Gotcha. With SDR/2020, what do you setup for gamma in the projector?

Wish I could pinpoint the source of the noise.
