Great, thanks.If it's update 1.76 it borks TV-led Dolby Vision on at least the G3, A95L and likely more TVs.

Setting to 4K may not have solved your problem only masked it.Got it sorted. Had it set to auto ,changed it to 4k all good now.
So what’s your answer.all the write ups I’ve seen say set it to 4k.Setting to 4K may not have solved your problem only masked it.
By setting it to output 4K you are telling the player to upscale everything to 4K whether it be 1080p, 720p or anything else, so you will probably be getting upscales 1080p not genuine 4K.
You need to find out why Auto is not sending 4K for a 4K disc like it should.
Please confirm which setting you are talking about, had this before and we were talking about two different settings.So what’s your answer.all the write ups I’ve seen say set it to 4k.
they definitely 4k discs, that’s all I buy now. I do have plenty of 1080p discs. I see you have the Denon 3800, I have the Marantz Cinema 40. If I set it to Auto in the panny 820 if I press the info button it shows Resolution 1080p then underneath that it says HDR 4k or something like that, I can’t put a disc in at the moment my wife is watching a tv program. Getting back on track if I then change it to 4k in the panny it shows Resolution 4k when I press the info button on the Marantz handset, which I would expect it to do. Hope I’ve given you enough info. Thanks for your help.Please confirm which setting you are talking about, had this before and we were talking about two different settings.
However if you are talking about Output then yes once sorted you can set it to 4K so that the 820 upscales proper 1080p etc rather than the TV but at the moment if Auto is outputting 1080p for a 4K disc you have a problem that needs sorting first, as you are probably getting an upscaled 1080p not genuine 4K.
First thing to check would be, sorry if this sounds obvious but have done it before myself, that the disc is a 4K disc and not a standard Blu-Ray.
I believe your Marantz gives the same info as my Denon so when its outputting 1080p what is the full info? If in Auto it’s something likethey definitely 4k discs, that’s all I buy now.

YCbCr4:2:2 indicates player led Dolby Vision, TV led would be RGB 8bit.At the moment I am unsure whether I am getting player-led or tv-led Dolby Vision. Any ideas how I can find out which mode is being used?
Thanks for the info will check later when I come round. Really appreciate your help.I believe your Marantz gives the same info as my Denon so when its outputting 1080p what is the full info? If in Auto it’s something like
1080p24hz
HDR
444
12bit
And when 4k
4K24hz
HDR
422
10bit
then the issue is bandwidth.
The theoretical max is
4K60hz
HDR
444
12bit
But the 820’s cannot achieve that so depending on the settings in the player and your HDMI cable it will cut one or more back.
Check your settings are
Video Format - Auto
4K (50p/60p) Output – 444 (assuming you are in the UK)
And in Advanced Settings
Colour Mode – Auto
Deep Colour – 12bit
If you still get 1080p I would try a different HDMI cable. If it is now showing 4K24hz you can set Video Format to 4K if you wish but Colour Mode needs to stay as Auto.

Thanks for the info. I can't say Dolby Vision looks bad in any way right now, but I'd certainly prefer tv-led to get the best image quality possible with the TV.YCbCr4:2:2 indicates player led Dolby Vision, TV led would be RGB 8bit.
Assuming your MZ2000 works the same as my Denon. My JZ1500 has no long press info so can’t check.
This might be worth a try as you have a new model.Thanks for the info. I can't say Dolby Vision looks bad in any way right now, but I'd certainly prefer tv-led to get the best image quality possible with the TV.
Perhaps in the next firmware version Panasonic should just add a setting where you could choose from: Auto (default), Player-led, TV-led.
This might be worth a try as you have a new model.
My JZ has an option in HDMI Setting for Dolby Vision. Mode2 forces Player Led but Mode1 sadly doesn’t force TV LED it instead uses EDID to determine which and this means on some new TVs with 1.76 on the 820 it will also use Player LED, maybe that setting is different on new models and allow you to select TV LED.
Good news if it matters to you, you are getting TV LED Dolby Vision.Hi, at the moment this is what it shows
If Dolby Visio.
Resolution 4k24
HDR Dolby Vision
Colour Space . RGB B/T2020
Pixel Depth . 8 Bits.
If HDR10.
Resolution.4k 24
HDR. HDR10
Colour Space. Y cb cr 444/BT/2020
Pixel Depth. 12 Bits.
Settings in 820.
Video Format 4k
4k (50/60) - 444
Colour mode Y cb cr (4.4.4)
Deep Colour. Auto (12 Bit Priority).
That is a different setting on my TV.Definitely worth trying.
The MZ has an HDMI HDR Setting, but you can't choose a mode in it, you can select between HDR Setting: Dynamic, Static, Off.
Off will completely deactivate HDR, I assume, Static will enable HDR10, Dynamic enables a second menu option below, HDR Dynamic Setting, which has on/off toggles for Dolby Vision and HDR10+.
The MZ has an HDMI Auto Setting where a mode can be selected for all four HDMI inputs. The first two (HDMI 2.1) inputs have three modes to choose from, the others have two.
I just tried all three modes on HDMI1, but with all of them I am getting YCbCr4:2:2 for Dolby Vision.
Bingo you sir are a genius, following your instructions with the same disc I get.Good news if it matters to you, you are getting TV LED Dolby Vision.
Anyway first set Video Format to Auto and see what the info is on the same discs.
Then set Colour Mode to Auto because if 444 isn’t causing this problem it will course problems on some discs.
I wonder if you watched the same YT videos I did but they are wrong and at least one of them now says so in the notes. I had it set to 444 at one point and if you go back far enough in this thread you will find someone giving me this advice.
By forcing 444 you are using up a lot of bandwidth and the 820 will lower other settings to compensate when needed, definitely on 60hz discs and I had issues with some other discs.
Auto will still use 444 if bandwidth allows and having “4K (50/60)” set to 444 is fine as it does not have the same effect.
If your TV is a few years old, new but cheap and/or fits into the optimiser settings I would say yes.Hi,Do you guys recommend the hdr optimiser on or off
If you are not buying a new TV this year, save for an LG G4.Update - if anyone cares - but useful info maybe, for others suffering the Pink Screen of Death.
It happened last night whilst connected to my Virgin TiVo box - so independently of the player.
And persisted when I turned the player on. But was OK with Freeview.
It resolved when I turned the TV off at the mains for 5 mins (so, rebooting it).
So... it's not the Panasonic player, it's the TV. It seems to sometimes have a headfit with HDMI.
I'll see how I get on but it looks like a new TV is required - I really can't afford it this year, having splashed out on the Blu-Ray player and a Denon DM41. But needs must when the Devil vomits in yer kettle.
