Panasonic UB820/UB9000 4K UHD Blu-ray player

Ideally I'd rather it not matter and just go with the flow. That 10+ is no slouch and I'm good with either/or.

From the specs I've read, Dolby Vision is still better over all than HDR10+, so I would leave HDR10+ off.

I don't use Universal remotes. I power each piece of hardware individually using their own remote. I don't route any electronics through my receiver since I don't believe doing so is wise.

CEC (Consumer Electronic Control) isn't about a universal remote or where its electricity is coming from, it's part of the HDMI spec since 1.0, with the last revision in HDMI 1.3a. Many manufacturers have their own names for it (i.e., Bravia Sync, SimpLink) rather than calling it "CEC," but it allows one device to send a signal over HDMI to a connected device to turn on, off, and switch basic things like input selections. It is active unless you explicitly turn it off in settings, and works even when directly connected to the TV.

It's that signal that can be different per manufacturer and create conflicting, out of sync commands that turn your Panny off right after you turn it on. (or, at least, that's what I'm thinking based on your description)

New owner. Can anyone tell me if the following is normal functionality for the UB-820?

- The grey "Reading..." and "4K/Dolby Vision/etc" rectangles freak out, flashing off and on several times whenever I play a disc.

- Signal loses connection to my TV (Vizio V585-H11) between the Home screen and the disc itself multiple times while a UHD disc is booting up. Also does this between the FBI Warning at the start of most discs and the label's intro logo before the menu.

- Menu pulsates and even the colors of the words *on the disc's main menu itself* (Title, Play, Chapters, etc) fluctuates between light and dark. Almost like the whole screen's brightness changes depending on the scene playing behind the menu?

- Whatever the first thing I see when the discs start playing (FBI Warning, etc). Flickers in and out three or four times very quickly. This only happens when Dolby Vision is enabled on discs, not HDR 10+.

- When Dolby Vision is enabled some scenes almost seem to lag when adjusting to the brightness or darkness when scenes transition.

All of these symptoms happen with Shout and Kino discs mostly, others are less affected I've noticed. I've tried updating my TV, updating the player firmware, factory resetting the player (not the TV yet), bought new 2.1 HDMI cables, tinkered with all kinds of settings on both the player and the TV. NOTHING is working to fix it.

Disabling Dolby Vision fixes the color fluctuation/flickering, but even on HDR 10+ all the other symptoms still occur.

Purchased on Amazon. Never had any noticeable Dolby Vision issues when streaming direct from my TV. This is my first Dolby Vision capable 4k player--if that info helps.

Any insight or advice would be great before I try to swap it out for another one.

Do you use a receiver ?

Try direct connection to tv to test if does the same things

Since it's a Vizio, is the HDMI mode set to 2.0 for the HDMI input the player is connected to?

I get some of those first two you list while the disc is loading but then it goes to the menu and everything is fine

I have a question about the hdmi settings between 4k/60hz(4:4:4) vs 4k/60hz(4:2:0).... I've never been sure about which one to go with, so what is the proper choice?

[Telemachus]

Found my first disc the UB820 won't play right, the remastered Blu ray for Dragons Forever from 88 Films. Plays on PS3/PS4/Sony X700, on the UB820 takes 1-2 minutes to load the disc with lots of gear sounds, then when I start one of the cuts same thing into the movie until it goes into quicksand and becomes unresponsive. I'm guessing maybe this is something to do with the intricate seamless branching this disc has. The UHD of the same film does not do this.

4:4:4 is what you want

[sapiendut]

4K/60 4:2:0. Using 4K/60 4:4:4 kills the HDR functionality when playing something at 4K/60

For 4K/24 4:4:4 HDR will still work.

Just try the settings in my signature

The player makes sure to keep the 24hz when playing since it's set to auto for 24fps. So my 4k's still play at 4K/24, but my concern was making sure I was presenting the image properly.

[sapiendut]

The native signal is 4:2:0 but one of many reasons the colour on the Panasonic appears better is due to its chroma upsampling turning the 4:2:0 to 4:4:4. And since pretty much all movies are in 4K/24 just use 4:4:4 for the 4K/24.

Uh...isn't that the wrong way around, unless I'm misunderstanding something here? If 4K60 is set to 4:2:0 it'll kill the HDR on said 4K60 content.

[sapiendut]

Nope. Try it out

I thought it also brings the content down from 10/12 bit to 8 bit? Unless if I'm mistaken about it.

That’s only for Dolby Vision encoded movies. 8bit 4:2:2 if I’m not mistaken.

I've tried everything. I even plugged it up on my other HDR 4K tv that can't do Dolby Vision. I tried four or five discs and they loaded much quicker and didn't default to the HDMI screen at any point.

So, I've come to the conclusion that the issue is most likely with my TV, not the player itself. But I still can't pinpoint exactly what the problem is. Probably a defect or something that is only affecting my tv unit when it comes to processing DV video thru HDMI? I also read a review of my specific TV model that there were issues with some HDMI ports not truly being compatible with 2.0 or 2.1 a couple years ago when I bought it (but can't find any info now). Maybe that's related?

Anyway, my cousin also has a TV with Dolby Vision, so I'm gonna go over and test my machine this weekend. If the color/brightness fluctuation isn't present on the menu screens, then I'm keeping the player and going TV shopping next!

Thanks everyone who chimed in for trying to help me out.

Uh...no. If the 4K60 setting is put on 4:2:0 then it knocks any such HDR content down to 4K60 8-bit SDR 4:2:0. That's what it's there for.

Guys, any clue why am I getting just DTS in my Sony receiver (dh790) display panel when I play blurays with DTS HD MA on my UB820?

My first thought of course is that is the receiver, but I cannot find the issue there. Could it be the player? It should display DTS HD MASTER AUDIO but it only displays DTS as if it were lossy.

Dolby Atmos and Dolby TrueHD are display perfectly correct, btw.

Any ideas?
Thanks so much in advance

Take a look at your audio settings in the player. BOTH Dolby and DTS have to be set to bitstream. It's not a global setting. Make sure Secondary Audio and Dynamic Range Control are off.
