Banding on LG OLEDs

The banding a lot of people are seeing on the LG OLEDs is apparently a bug in the image processing. If your UHD player has the relevant setting it can easily be fixed. Do not use YCbCr 4:2:0 or 4:2:2. Use 4:4:4. I was seeing a lot of banding in the otherwise reference disc, The Revenant. When I switched from 4:2:2 output on the UHD player to 4:4:4 all of the banding instantly went away.

The reason that this is a bug is that the difference between 4:2:2 and 4:4:4 should not affect this. 10-bit color depth should be sufficient to eliminate banding. The fact that it doesn't means that there is something wrong with the LG's processing of 4:2:0 and 4:2:2 signals.

Was the 4:4:4 signal still sending 10-bit to the display? I know 50/60 Hz HDMI 2.0 modes are limited to 8-bit at 4:4:4. If the player was doing some kind of dithering while converting to 8-bit or maybe just during the 10-bit chroma-upsampling, maybe that's what is reducing the appearance of banding. Sites like rtings.com have tested OLEDs using uncompressed 10-bit gradient images (not video) and still found banding in darker colors.

Interesting. Do you know if LG is aware of the issue? I've been in contact with marantz because my roku exhibits banding when passed thru my receiver but they just responded that they think it's a B6-specific bug and are attempting to pass that along to LG...

Any updates on this one? I'm seeing banding all of the time on cable, Netflix, XB1S, etc. Perhaps just bit-starved feeds?

I notice the banding on my 65B7 on HBO Go and Showtime apps from my Apple tv. I am passing it thru a Denon 4300 receiver and letting the tv upscale. I may try the trick of going thru the Oppo 203 for upscaling and tweaking the color output settings like TomHuffman suggested to see if that makes any difference. If nothing helps i've decided to just wait it out a year til the next gen Sony OLED comes out, hopefully without the crazy sound system and non-detachable rear piece.

If you want a particularly bad example of the banding try watching The Wizard of Lies on HBO Go. Crazy!!

Try it hooked up directly to tv. Not 'passthru' or whatever. Cant stress this enough that to diagnose a problem you have to eliminate variables from the signal chain.

I had the very same issue. I have a 55" B6 OLED, Marantz SR5011 and an OPPO 203. All I did to resolve mine was went into my OPPO player settings and changed display to 4:4:4 / 12-Bit. Resolved it for me.

Oled 65 eg9600-ub

Can someone tell me which one OLED 2017 LG or Sony do not have what I have with my LG OLED 65 EG9600 made in March 2016, curved, 3D? See attached picture. I have poor gray color with hundreds of shades of gray. I was watching Underworld in 4K with Sony 4K player and it was very annoying to see these band, like a dirty window screen.
I paid a lot of money and I have the most expensive Best Buy warranty. I am going to replace TV using all necessary arguments and my very expensive warranty.

The picture is taken when I am in Youtube search window. I have Ethernet cable connected to TV, the Internet has no issues. As I said it was the same bad dark gray for 4K Underwald played on Sony UBP-800 default settings.

WHICH ONE SHOULD I GO? LG C7 or Sony?

Thank you.

What you see is vertical banding on dark shades of gray. This is unfortunately inherit to the OLED panels now. But this issue has been minimized in the newer models. I am sure you see lot less banding with both Sony A1E and LG C7. As for picture quality, A1E does a better job with low quality / compressed sources (like cable, and streaming). I suggest after getting your new TV to test for banding and uniformity to make sure you don't have a big problem before return window closes.
Good luck

I have a similar issue with my B6. Some minor adjustments to picture settings make it a tad less noticeable, but you know it's there. I'm done playing panel lotteries. I'll stick with it and maybe upgrade in 2019 or something.

Are you talking about jail bars (banding on dark grays)? If so have you tried IRE 5 adjustments to minimize this effect?

It's this, with a 5% grayscale image. So I suppose yes, the jail bars. What are the IRE 5 adjustments? Never heard of those.

EDIT: Won't let me link the picture for whatever reason but yes - it's the banding on dark greys. I notice it on movies such as underwater scenes from Deepwater Horizon, etc.

Tested at Best Buy Sony OLED and C7

I tested in Best Buy both Sony OLED and LG C7 with help of one associate in Cambridge, Ontario Canada. BTW, a sales rep in Kitchener Best Buy (Asian guy) was a jack ass and rejected my request to go to youtube and run few videos for DSE test. Nevertheless, the test was bad for both Sony and C7, same as mine EG9600.

OLED is not worth it. All "Black level" hype is not worth it. Grey uniformity is bad and you cannot watch Batman or Underworld and enjoy it. I am stuck, probably ask for a refund.

I notice it the most in the menus, which I assume don't have a lot of color levels which might produce the gradient banding I'm seeing? and when the camera pans across an open sky, with different shades of white/blue/light blue/gray. I watched my first ever 4k UHD movie, The Revenant , and everything looks great (faces, fire, motion, etc) except the sky/different shades of open snow, which is a lot of the movie.

I have gone back and forth, turned off/on every setting under the HDR picture settings on the TV menu (Dynamic Contrast, Super Resolution, Color Gamut, Edge Enhancer, Color Filter, as well as the basic contrast/brightness/etc) as well as the Blu Ray Player's settings (Resolution, Movie Frame 24Fs, DVD 24Fs Conversion, HDMI Color Format, HDMI Deep Color. Still cant figure out what is causing it, I reset everything to default HDR setting on the TV, thinking I had made a mistake, but I'm not sure where to go from here.

Current setup

Samsung UBD-K8500 4k blu ray player into an Onkyo TX-NR747 into the LG OLED65B6P
There is issues with the Denon and Marantz when plugged into their AVR. Same banding in the sky of The revenant.

Can you try plugging the player directly in the TV without going to the receiver first.
if I connect my player directly to the tv I won't be able to get atmos through arc.

Coming via HDMI (with HDR metadata embedded) -> Denon AVR-X6300H -> LG Signature 65“ OLED65B6D

We have Banding artefacts in some highlights.... NO it's not in the source..... going directly to the LG 65B6D without Denon AVR-X6300H there's no banding and no artefacts.

definitely an Denon Bug....

Asked the support....I hope getting an answer or an firmware update.....

It's up to thetvs processor to hopefully fix that. Sony A1E is going to be the first OLED to market that fixes this color banding issue. The use of the X1 Extreme processor means that it can break up the solid bands of color in the 8-bit (SDR) or 10-bit (HDR) source content, by up-converting it to a 14-bit equivalent gradation, with 64 times more color levels. Super bit-mapping and fine color gradation.

"By extending conventional 8-bit and 10-bit video to 14 bits, because consumer televisions cannot handle this 14-bit signal directly, Sony applies 'Super Bit Mapping for Video' technology. Advanced digital error diffusion breaks up the solid bands of color, effectively smoothing out the gradation. The result is nearly the equivalent of 14-bit gradation in an 8-bit/10-bit output signal." So, the Sony OLED will eliminate color banding that is still a major issue with LG OLED models.
Well that explains it. I just bought a B7 and I figured with HDR color banding should be a thing of the past. Load up Shadow Warrior 2 on my PC which is a game that beautifully supports HDR and nope, still banding, easy to notice when you look into the clouds. What's interesting is that HDR mode has MORE banding than good ole 8bpp mode. I'm guessing there's some kind of dithering algorithm that's turned off in HDR, such that color banding actually becomes worse in HDR mode. How ironic. This TV seems so half baked that I'm almost convinced I should return it

I own the 4k version of Underworld Blood Wars and it looks great on my Sony A1E and Panasonic 4k player. Do you have a particular time stamp/moment in the movie that seems especially bad that you can direct me to. I'm not a good picture taker but I can try to take a picture of the moment to give you a vague idea of how the scene looks on my television.

Having the same problem with my B6 connected to Denon X4300 and HDR Games on Xbox One S (had it on PS4 Pro as well) and also when streaming HDR Content via my Nvidia Shield TV. Still no solution? It doesn't seem so problematic on UHD Bluray content...

Wow - one year later and the problem still exists!

Apple TV 4K -> Denon x2300w -> LG B6

I see color banding when ATV4K is sending HDR10 content. ATV encodes them as 4:2:2 signal (even though original is 4:2:0). Its not the HDMI cables because color banding occurs even when ATV output is set to HDR10 [email protected] (ATV always sends this out at 4:2:2; no option for 4:2:0). That is much lower bandwidth than HDR10 [email protected]@4:2:0 (no color banding). So something is wrong with the Denon.

Connecting the ATV directly to the LG ... no color banding!

Can you elaborate on what material you used to test it. I tried the latest Denon firmware and I still had HDR color banding issues. Very irritating.

If nothing helps i've decided to just wait it out a year til the next gen Sony OLED comes out, hopefully without the crazy sound system and non-detachable rear piece.

If you want a particularly bad example of the banding try watching The Wizard of Lies on HBO Go. Crazy!!
Are you seeing banding if you bypass the Denon entirely? I notice no-banding on 4:2:2 material if I connect directly (Apple TV 4K -> via certified premium HDMI -> LG B6).

I too am having this issue on a LG 60UH7700 TV.. This TV is not OLED but I see awful color banding when I watch any HDR content from my Nvidia shield. I thought the problem might be the Nvidia Shield so I tried it on our Sony 900e and it played completely fine.

After digging around in the LG Picture settings while an HDR content is running. I found a setting called HDMI Black Levels.

It was set to Low.. I changed this to HIGH... and BOOM all the color banding was completely gone. I then set it back to Low and it was still gone. So this setting is breaking something.

Can other users also try this and see if it fixes it for you. If this does fix it.. I suggest everyone start submitting issues to LG asap..

I registered just to say THANK YOU. I have been killing myself over this for nearly a year and this setting “solved” my color gradient banding issues. Look at the positive.... I am a lot more knowledgeable about HDR now!

Clearly a bug. I wonder if LG knows or has a plan. I have a 65 OLEDB6p - wonderful set now. It was driving me and my guests nuts. Nvidia Shield -> Vizio Atmos Sound Bar -> HDMI Arc

Now if I could just get the shield to keep an active source connection when I turn the tv off and on. Always have to suspend it manually to pop the image back on the screen. Not wife approved.

Thank you, thank you, thank you.

Firmware 5.30.25 and says no available updates. So I think it’s the latest. Maybe I need to force a particular version.
