I think you were right. I changed the picture setting back to Cinema during playback and all is well. thanks

What Sonoftumble was saying is that the TV has SDR picture modes which you are familiar with (Cinema, Technicolor, game, etc.) and you can turn on or off Trumotion for each one. But, when the TV detects HDR or DV two completely new sets of picture modes become available (but with the same names mostly), so you have to disable Trumotion for each of those sets too.

What is the best methodology to definitively check for the lookup table flaw?

Pump up the backlight and what color screen? It's so hard to tell on the 5% grayscale test.. I'm wondering what the best static color should be to try to detect it. I feel like my 65 may have a barely noticeable box but I can't be 100 percent certain.

No need to pump up the backlight. Any full color screen like magenta, pink, yellow, orange , red you should have no problem seeing the problem. Just use you tube and search for the specific color panel color. With my set I was only able to see it when watching regular content if the background was predominantly one color. A Honda or Little Caesars commercial showed this issue but if I had not read about the issue here I probably would have never noticed the problem otherwise. Glad I did though and happy that the panel got replaced without too much hassle. My biggest concern with having the problem rectified was not knowing what if any long term repercussions there would be if not fixed. Hopefully for me this is the end of the issue.

I'm going nuts trying to get anywhere with customer service. Figured I'd try posting here, didn't put it in the owner's thread to hopefully increase its visibility... This is pretty much a copy/paste of a question I asked on Reddit a month ago.

The USB ports (and therefore the USB powered bias lighting) on the back of the TV sometimes stay powered on after the is turned TV off. Usually, the USB ports turn off 5-10 minutes later. No big deal... But after updating the TV recently, sometimes the USB stays on indefinitely. I wake up in the middle of the night 5-6 hours later and notice the bias lighting is still on meaning the USB ports never powered off.

My theory: I asked this on reddit last month and was told that when the USB ports stay powered on after turning off the TV it's an indicator that the TV is doing an automatic pixel refresh. That every 4 hours of accumulated screen time, it does a pixel refresh for a few minutes. Additionally, after 100 hours of screen time it does a longer 1 hr pixel refresh. Now 6 nights out of the week, the bias lights turn off instantly or within 10 minutes, but approximately once a week this issue occurs where they stay on indefinitely. I'm thinking there is a bug with the 100hour/1hr pixel refresh and it doesn't end when it's supposed to. That would explain the seeming randomness of it.

This definitely just started occurring after I updated the firmware recently, but honestly I'm not sure what firmware I was on before this...I don't think my TV was connected to wifi for a while.

tl;dr: Updated my TV's firmware to 5.80.15 a couple months ago, since then -sometimes- my USB-powered bias lighting stays on indefinitely after turning off the TV (meaning the USB port is still powered on). This occurs approximately once a week...Normally it shuts off instantly or within a few minutes.

Is anyone else experiencing this?

P.S. While type this and banging my head against the wall with customer service I supposedly got through to a LG "OLED Specialist" (that none of the tech support people were initially willing to let me speak to directly) who said the would look into it and test it on their own TV they had in office as well as escalate it to the engineers. I have no idea if he was just trying to get me off the phone but seemed much more understanding than the general tech support I had previously spoken too. Seriously, I felt like that 14 year old kid who discovered the Apple FaceTime bug and his mother, trying 16 different ways to report the bug to Apple and no one would listen or take them seriously. Trying to get past CS reps to report bugs to people with actual technical knowledge is insane.

The Dolby Vision app added some trippy new clips I hadn't seen before.

Try turning off quick start. That should fix your problem.

Well, I've discovered that when I disconnect everything and power the AVR and TV back on alone, ARC is working again. But, as soon as I connect ANYTHING else, ARC stops working. WTF???

I didn't read your previous threads, but with this last post it seems there are many variables in play, may I suggest resetting the AVR and TV to factory settings and set everything up from the beginning and reference the AVR specs in the process. If I read correctly your AVR is HDMI 2.0a and not 2.0b so there could be some issues with any HLG or DV content (was there a firmware upgrade for DV?), HDMI inputs 1-3 are different than the rest of the AVR HDMI connections too, etc.. And of course, if there's any doubt about the quality or performance of any HDMI cable consider upgrading it too.

Certain devices when connected can completely block all hdmi-cec commands (and arc).

One of the other devices you are connecting to your avr is likely the problem.

I had the opposite problem. AVR, TV, and media player all working well together. Powered down the media player and lost ARC. Power it back on and all was fine again. Keep playing with the configuration until you find what works consistently.

Did we determine that the issue with one half of the screen being darker than the other half is a lookup table issue? I only heard about the rectangle.

Well, I'm really trying to avoid all that because I have all my settings tweaked how I want them and I'd rather not have to do it all over again. So, for now, that's a last resort. I'm honestly not sure if it's a or b but to my knowledge it shouldn't particularly matter for ARC.


My issue is... NOTHING else has changed but the Firmware on the TV. Everything else was working just fine before the update. So all the other cables and devices shouldn't matter now. What changed?

I'm sure LG knows by now they created all kinds of issues with ARC with their last update. I've emailed them and had it escalated to their software/engineering team because of the missing rear surrounds in Atmos content (when using ARC) after that last update. Now it's just a matter of how quickly they will resolve these matters. It wouldn't hurt to email LG support until they get on it. I'll do so once again in a few weeks if nothing comes along...I know these things take a certain amount of tweaking, testing, and time before another update is pushed out, but it never hurts to be persistent.

After reading so much about uniformity issues and image retention, I have found myself constantly looking for it while watching TV instead of just enjoying it.

So... I have decided to run the 5% grey test on my 55 B7 which has 1700h on it and the following is what I got.

Is it OK or should I worry about something ?

The irony is that overall, OLED's have better picture uniformity than LCD's ( https://www.rtings.com/tv/tests/pict...een-effect-dse ). All OLEDs have what you show to some extent and it's only visible in normal viewing for a very small percentage of owners. If you don't see it in normal viewing, which is the real test, and it seems you don't because it's been there for well over a thousand hours, then it's not an issue. But, that small dark splotch is unique, or maybe it's due to the low resolution photo.

Its true that I do not see it in regular viewing but my worries is that this is going to develop beyond the warranty time, which is in 3 months, and after that it will be difficult to get it replaced.

would you recommend asking for LG tech to come and have a look at it or should I leave it as is?

I can't see anything wrong with that picture, I would leave it as is.

I think that is extremely minor banding. Mine has much worse and am working on a replacement. I would stick with it if I were you and I'm not sure they would replace it, you might have to fight with them.

My B7 has that but my B8 is flawless, so they have definitely improved. Now that I see both from one room to another it really made the B7 banding stand out.

It's not a clear photo, but it suggests that your banding is better than in my 55B7.

I don't see banding in normal content (except for a horizontal rectangular block in the lower left corner of the screen, which can be slightly visible). I haven't checked the number of hours on the screen (purchased November 2017), but I believe that the banding has not increased over time.

If you can avoid worrying about it, that would be good.

The real trick is to never look! If you haven't noticed anything whilst watching TV why search for problems and the consequent stress?

Pretty sure I have this issue. It's slight, and doesn't always show up, but I have caught it now and then, across the whole spectrum of content (SDR, HDR, DV, game, etc). Am interested in knowing this as well, and if LG fixes out of warranty, or what else I may do to address it?

One of the better ones I have seen. you have no worries

Thank you all for sharing your analysis with me. I think I need to "work" in myself to stop looking for it and just enjoy it :-)

Well guys,

My 1st 65B7A panel got replace because of burn in about a week ago. The new panel has very bad 5%,10% vertical banding as you can see in the pictures. Now they are coming back out to replace panel again. I will keep you guys posted.

I just got the Sony WH-1000XM3 after reading the reviews and they do not pair with my OLED65B7A.
I had tried a friends Bose QC 35 II and they paired just fine.

Had I known about the pairing, I would have bought the Bose

Correction, They do pair. I had already paired the headphones with my phone and had not realized that when pairing with a subsequent device, the power button on the headphones has to be help for 7 seconds to pair. I should have RTFM before complaining about these fine headphones. All is well!

I use some cheap Monoprice over the ear. I have a number of pairs of headphones though, never had an issue pairing. I guess it’s good to know there are those headphones out there that won’t pair.

My XM3's pair just fine

I have a 65C7P and was considering getting the Sony XM3s. I would be interested in knowing if others have had trouble pairing them. I only own one cheap pair of BT headphones and they are the iSound BT2500s and I have been unable to get them to pair.

I amended my original post. They paired for me also
