2023 build date on mine used everyday since buying no problems, maybe they did address some issues of older units with the trays :knock on wood: I think going through three bad units seems like awful luck maybe buy somewhere else and not worry about modding I dunno (mine isn't modded).

For the movie picture modes, you're better sending 4:2:2. Using the Spears & Munsil test patterns, it's cleaner with 4:2:2. Of course, again, this is only seen with test patterns and in the grand scheme of things I wouldn't worry about it either

I do 4:4:4 but have LG, do you think it's worth switching to 4:2:2?

I've had mine outputting 4k only for awhile, there was a visible difference to me with Blu ray upscaling vs. my LG, the Panny looked better way up close for grain detail. I don't play DVDs on this unit for reasons that became obvious (they look like ****) so I use a good old Toshiba deck from 2007 outputting vanilla 480i and the picture sings for me letting the LG do everything.

I'm not familiar with the specifics to how LG handles it, you would need to use chroma test patterns from the Spears & Munsil discs (even those patterns are difficult to discern). And as I said earlier, I can't tell with actual content. It's just one of those that I tested on a few of my Sony TV's over the years and noticed it, and after some research it was determined that Sony's picture movie modes do better with 4:2:2 12-bit signal (unless you have it in Game/PC mode, they accept full 4:4:4 12-bit).

I seem to remember when I was using Auto that the player would send a 1080p signal to my TV while playing a bluray, there was a box that would pop up saying the resolution has changed and the TV info would say 1080p. Maybe they changed it on a firmware update this was nearly 3 years ago.

The 820 has to be changed to a specific resolution to switch from my experience. I have some 1080/60i Blu rays and didn't want them upscaled and I had to put the player into that resolution.

Unfortunately, it is manual toggle only. That was one of my gripes with Panasonic players. It didn't allow a "match content" setting like Oppo and the Sony X800M2 let you. You had to manually change the resolution.

Auto just detects your display's resolution and will output at that.

[rroeder]

Hmmm, not sure what I'm remembering then, there was some setting that kept giving a box to OK. I changed it and it went away. The 4K setting works for me tho, the player upscales as good as my TV does.

On UHDs that have both HDR 10 and Dolby Vision is there a setting to set DV as default?

Also, if its right that DV automatically enablrs motion interpolation how do you turn it off and keep it off?

Huh?

HDR10 is the base layer that your setup will fall back to if you have a component in the chain that cannot do DV. However, if you have DV turned on at the player and a display that can deal with it (i.e., not Samsung), DV will be the default.

Next, DV does not have anything to do with motion interpolation. Many displays run different settings for each mode they enter, so even if you changed settings on standard mode, if you didn't adjust things when a DV title was playing, your display probably still has its out-of-the-box setup, which probably includes that motion smoothing. During DV playback, change your settings that you want, including motion interpolation, and the display should keep that every time DV is displayed.

Hope that helps.

The OP may be talking about if a 4k title has HDR10+ and Dolby Vision, and whether it will default to HDR10+ if the display also accepts that format.

He is and no there's no way to make DV default for discs that have both DV and HDR10+.

Ahh, good catch. Yeah, if they did mean HDR10+, then I think that was covered a couple of months ago in this thread, and I think you either have to turn HDR10+ off, or let the player pick that over DV. I don't think there is another option. (Rottweiler30 should search the thread though, I think it's been covered thoroughly.)

Hi All - I have been scanning through the thread but can't seem to find what I am looking.

I got this player about a year ago (UB9000) great player but notice that the discs are quite hot after playback. The player itself seems fine it just the disc. Is this normal or a problem?

Normal. Reading the innermost layer requires some pretty high RPMs, which equals more heat. They shouldn't be uncomfortable to handle, but feeling like toast just out of the toaster is normal for mine.

I got the UB820, and have noticed in the last month or two the picture flickers every now and then when watching a movie in dolby vision. This only happens in dolby vision. This happening to anyone else?

Might be a bad HDMI cable.

Happened to me, every 20-30 min and only in DV. Tried a couple different cables with no luck, finally got a Monoprice 2.1 cable 3 ft. and it's 99% fixed it.

Curious to know if HDMI 2.1 cables help with some of these issues, even if the equipment at either end is not 2.1 compliant. The cable shouldn't make difference in those cases, but does it?

In theory it shouldn't, but I do have my player hooked in through a Vizio M soundbar since my LG TV won't pass through DTS signal. I decided to have everything in the chain hooked up to 2.1 for consistency, and for one reason or another, it's worked.

Thank you! I switched the hdmi cable to the monoprice 2.1 and it seems to be working.
