Thank you. Never knew that.

I've never had to do that before.
What gives?

First and foremost, you didn't have to turn off the HDR10+ setting as it doesn't affect any of the Marvel films since they either are HDR10 or Dolby Vision.

Black Panther is in Dolby Vision as well HDR10. Based on your experiences, it's quite possible your TV isn't replicating Dolby Vision properly and that it's better at playing HDR10 content. But there are many factors to this (like TV settings when playing Dolby Vision content vs. HDR10) which is why you need to look into all possibilities.

I would look into those and see if maybe your Dolby Vision settings in your TV needs to be changed because Black Panther looks pretty good in HDR10 and Dolby Vision. It's not amazing by any means thanks to all of the CGI, but it's still pretty good overall.

Quick question for all of you, do you leave the picture settings for DVDs on the 820 alone/have them on default or have you all adjusted them? I know the default has a bit of edge enhancement other processing activated, which I would assume helps the upscale to 4K but, I would like your guys' thoughts on it?

No adjustments from defaults aside from turning all the noise reduction off and putting Chroma on -1 for all sources.

In any case, he's answered his own question. The Optimiser is a blunt instrument, always has been, and as internal tone mapping solutions improve, along with the proliferation of DV and HDR10+ content, then its usefulness is receding.

Awesome! Kind of figured I needed to turn the noise reduction off. What does setting the Chroma to -1 do though?

The Panny UHD players are known for their, ah, robust reconstruction of the quarter-res 4:2:0 chroma channels but on the default setting it adds too much ringing for my liking, even if it's only something that's visible on a test pattern.

Setting it down to -3 or -4 makes it look more like previous Panny BD players like my BDT310, but that then seems to soften it too much. So even though -1 makes only a fraction of a difference I leave it there to act as a placebo as much as anything

Hey, a fraction of a difference is still important. Anything that gets close to perfect is worth it! Thanks for the info!

Big FYI. Black Panther in the Infinity Saga set does NOT have a DV layer on that disc. IF someone bought the original SINGLE release of Panther, it is the only MCU movie disc that Disney ever made with the DV layer before they decided to stop using DV on disc.

Same with Star Wars. Only original The Last Jedi single release is only one with DV. The later release of SW 1-9 set had DV omitted from the disc of TLJ.

To my knowledge, Disney has not used DV on a disc release ever since those two.

As an aside, it's interesting to see another user having issues with viewing Black Panther on a TCL display. The horrific black crush and overall dreadful-looking image yielded by the (long since replaced) 55S405 on that title specifically pretty much triggered my awakening of sorts to the fact that, not only are all 4K TV's not created equal, many are a downright scam.

Thankfully with time (and some helpful input from users on this forum) I was able educate myself on HDR panel technology and the integral importance of things like full array local dimming and peak brightness when it comes to tone decent mapping on LED displays. Since then I've done my best to guide many friends as they've looked to purchase new TV's over the last few years.

So yeah- thanks Black Panther. You look mighty nice on my Sony Bravia.
Hopefully TCL gets their $h!+ together one day. (doubtful)

I had an ex-friend who had a Vizio LCD that was quite cheap of some sort that had Dolby Vision and HDR10. It was just as bad as you'd think it would be but they then switched to a 48 CX later on. There's a X900F downstairs but I personally couldn't stand how the FALD was on that set and the input lag for games was quite severe.

Last time I watched this exact disk, it was the same TV but the player was the Sony x700.

But this also doesn't explain why ONLY this disk Infinity Saga set or otherwise has this issue! No other disk does.

I have the TCL 5-series. Not the 4-series.

I'm going on three years with the X900F, and while it's far from flawless, the local dimming is as good as any other LED I've seen in its range, including the newer Bravia models. Sure blooming and light bleed can be an annoyance from time to time, but Sony has done a rather nice job of improving those issues through Firmware upgrades.


My main complaint, overly-searing highlights with HDR10 material, is something that's been almost entirely ameliorated through use of the optimizer on the UB820. -of course with streaming material I'm still left to fend for myself

I guess OLED has really spoiled me ever since I started using it long term with my Note 3 many years ago and especially once I got my CX back in November/December. I've had a few niggles with the tv (Atmos/TrueHD bit streaming dropouts with some Disney titles pre-reciever, sudden audio dropouts that can cause popping when changing formats when using eARC, and the TV completely ignoring DV signals yet sending a proper EDID due to a dicky FW) but other than that I'm very satisfied with how its performing its very much the perfect TV and a definite jack-of-all-trades.

OLED is no doubt the king when it comes to exacting contrast and pure blacks. When a good friend was trying to decide between the latest Sony LED vs an OLED model from the prior year I told him to grab the OLED if it was a feasible option. He did and has continually thanked me for my advice on the matter almost every month since lol

Personally though I'm happy enough with the (rather striking) picture quality delivered by the X900F that the idea of plunking down another 2+ grand for yet another TV just isn't appealing. That may change as display technology continues to evolve, but for now I'd rather invest that money in continuing to expand my 4K library of films.

Thanks Geoff for your feedback; it's good to know I'm not crazy and I know you know your stuff. I will likely share the same question in the official thread to get the feedback of others who own the unit.

Hi folks. I made the mistake of posting this is a new thread, and was re-directed here. Geoff D was kind enough to chip in, but I'm curious if any of you are using the 820/9000 with a newer OLED TV, and still using the HDR Optimizer feature. I just purchased Sony's A80J, and to my eyes, leaving the feature off lets the TV get brighter without obvious signs of clipping (I used Into the Spider-Verse as a test disc). That being said, my eyes are often wrong.

With new OLED TVs, like the A80/A90/C1/G1, is it worth using Panasonic's HDR Optimizer, or are new TVs good enough at dynamic tone mapping that the feature is unnecessary?

When I tried the Optimizer, it was quite inconsistent on a title per title basis; some made no real difference while others were more constrained in terms of brightness. I could definitely see a use for this with non-OLED screens but for me at least I have it off.

[evoll]

I have a 65 A80J and i use the optimizer. With 1000 nit discs i see no difference with it on or off but when i put in a 4000 or higher nit disc i can def see a diff. with the optimizer. I put in the pan 4k disc and with it on it brings back more color and less bright highlights being blown out. My oleds all have been calibrated so i know it's not to much contrast or setting wrong on the tv blowing out highlights or color.
