Panasonic UB820/UB9000 4K UHD Blu-ray player

You are simultaneous discussing you own playback media issues in two threads. Why?

Do you not understand this comment at all?

It's difficult to explain -- and I'll try to take a pic the next time I watch the disc -- but it's like that area to the left of the red book in that opening sequence begins to dance and twitch, with severe artifacting that makes the whole "box" the book is sitting in look weird and "jumpy"...

Not to correct you John, but it's three threads now.

[sapiendut]

I don’t even know which thread I’m in anymore. Everything is the same.

Replied to your Civil War PM, Chip; thanks.

it's your TV

I know that leaves the final denominator, but why would the display cause this if my settings are correct and the players are sending over an upscaled 2160 signal? What would go wrong?

I have no idea what TV you have and what "correct" settings mean to you, but it's obviously an issue with the TV doing something. You don't have 3 defective players exhibiting the exact same issue on the exact same scene.

My TV is in my signature...

But at any rate, it's a Samsung NU8000, and what I mean by "correct" is that I'm in Movie mode with settings that would affect something like this, such as Sharpness, adjusted right (on Samsungs, that's "0" on the slider).

It may not be three defective PLAYERS exhibiting this, but it could be that I got a defective DISC.

Even still, what would cause a television to do this in a particular area? Any ideas? Is it false-contouring or something along those lines?

I doubt it’s the disc

You see how he treats ppl who try to help them? A snarky comment and an eye roll.

So what would contribute to this weird artifacting/shimmering in that one scene from a display perspective? The sharpness isn't up too high and everything else is pretty much where Rtings adjusted their NU8000; what's triggering the display in that one sequence?

I informed Chip that I am going to try the disc in my DMP-BD10A in our bedroom, which is connected to a 1080p LG LCD, to see if the 1080p-to-1080p connection exhibits the issue.

It can be simply the video processing of the NU8000 is just not up to par. I don’t know. I know for a fact though, even up to 2019, Samsung TVs colour accuracy post calibration is not accurate. They just can’t be made accurate.

This guy IntelliVolume is a work of art. This is better than a TV soap opera show. No matter what player he will get it will not be perfect. First get yourself a good TV not a edge lit model and not a Samsung. Try a top line Sony. And forget DVD's for gods sake. Enjoy the bul-rays and the 4ks. I have two Oppo 203's and a Oppo 83 and a Panasonic 9000. They all are working super with my top line Sony TV.

Okay, but we're not talking about color accuracy here -- we're talking about moiré-like artifacting that makes that area near the book twitch around. I don't have an issue with my display -- outside of the blooming HDR -- with regard to color or image.

If the video processing isn't up to par, then why is this the ONLY disc I've ever watched on this thing to exhibit this? Especially a Blu-ray coming over as scaled-up 2160p...

Usually a better quality UHD BD player such as a Panasonic UB820 or UB9000 is run through a battery of video tests to verify its operation is as good as it gets as a SD to UHD source. However don't believe that ones TV is as good.

The below is from a fairly recent Reddit submission entitled Diagonal moire pattern on Samsung TVs?

Not easy to pin down anyone identifying this. I have noticed that Samsung TVs tend to fall into one of two categories of artifact. Either they have a tendency to display a diagonally-oriented brighter/darker pattern, or they have a tendency to display a vertically-oriented brighter/darker pattern (the latter case making the screen occasionally look like it's almost 1080p due to the bright/dark line pattern that goes from top to bottom). Seems to occur largely on smooth gradients of color, such as a blue or orange sky shot. Also seems to be a temporal artifact -- a non-moving still image seems not to produce the phenomenon.

When walking around Best Buy and similar department stores, it seemed the diagonal pattern tended to affect all or most of Samsung's newer models, including their top QLED, while the horizontal line problem is something I only spotted on a two-year-old model that was on sale. But I never established any solid pattern.

Rtings doesn't seem to have any test in place that checks for problems that would only appear with video in motion, so I can't say I'm surprised nobody seems to have brought this up.

I tried getting photos of these two phenomena while I was in one of the stores. Pretty straightforward for the vertically-aligned problem:

[Show spoiler]

Quite blatantly, every other line is a completely different hue, and this has a very blunt effect on how the image looks. I neglected to get a photo of the Samsung model this shot came from.

The diagonally-oriented phenomenon, which I assume Samsung adopted since it's more subtle than horizontal lines, was not so easy since I had to wait during a video in motion for whatever conditions engendered the issue. But I got one. Please excuse the lack of focus. The phone did its best.

[Show spoiler]

This was a QN55Q60RAFXZA. You can see in the middle how every other pixel is more red or more yellow, and on the left, it's even more obvious, with every other pixel being visibly brighter or darker. Basically, it's the same issue as the (older?) horizontal line problem, reoriented to make it less obvious, and conceivably masked by the fact that the resolution is 4K. My father owns the top QLED from last year and his TV is actually the first opportunity I had to notice this issue (along with the almost undefeatable brighter/darker phenomenon which fortunately people do seem to know about).

I want it to be perfectly clear that the videos being displayed when these problems popped up were not the cause of these issues. They were legit 4K videos (not 1080p), and these are not digital artifacts. The issue was evident regardless of which store I visited, and indeed fully evident on a unit that was purchased. So no tossing around blame on this. It's something Samsung did as some kind of hardware shortcut that inherently wouldn't ding their review scores.

For the nonce, I hunted around for TVs that didn't exhibit either problem and it seemed to be limited to Samsung. Sony TVs, evidently, did not opt for this cheap shortcut.

I have a Samsung UBD-M8500 and it's fine but I'm starting to experience some weird quirks.

I'm considering the Panasonic UB820. Anyone mind chiming in if they think this would be a decent upgrade? Are there any known issues with they 820 or is it pretty solid all around?

I upgraded from the Samsung UBD-M8500 to the Panny UB820 early last year (I wish I had done it sooner).

My Samsung player had a lot of issue with signal drops, since upgrading to the Panny I haven't had any problems.

It's the Panasonic UB820/UB9000 4K UHD Blu-ray player thread, David.

[dcx4610]

How is the Panny 420 compared to the 820? I strictly use my player for playing movies. No streaming and I don't need any advanced hookup options.

I like quality but at the same time, once I see players around $500-1k, it just feels like overkill and I'm not sure if I truly notice a difference.
