Yes, that's been my experience.

You're not kidding! My head is spinning from all the various recommendations and variations, lol. What you wrote though is what I finally concluded, and this is how I have my system set up: Console set to "Automatic" and TV to "Low" for HDR and "High" for SDR games. I'm using this input for the PS4 Pro (gaming only!) so that makes it easier. But, I have to say, even with this configuration I'm still seeing some black crushing. I noticed this last night when trying out Fallout 4. The game's environment looked stunning, no issues, but then when the player ran into Codsworth and started interacting with him, the cutscences were nearly black and almost monochromatic. No detail or color noticeable. That's what made me think maybe I should change the input icon/label.
You are seeing black crush because your settings are still wrong.

Set the TV to Low (this is the default), and set your PS4 to Limited. This will apply for SDR and HDR.

You always want the TV and the consoles to match, so low with limited and high with full. In almost all cases, when not using a PC, you want low/limited. This will fix your black crush issues

Hi all,

I've enjoyed my LG C7 65” OLED for 8 months now. Last week, I learned about a protective plastic film on the BACK of the C7.

So I looked behind my TV and saw the film was still there on the back of the thin part of the screen (it did not cover any ventilation grates, it was overlaid on the aluminum—very hard to spot, and I'm thorough :] ). Unlike the film that was on the front of the screen, there are no labels telling to remove this. I don't recall anything in the manual about this either.

I've put in about 175 hours on the TV with the film stuck on the back. I’m concerned about the damage leaving the film has done to the picture, as it might not allow for proper heat dissipation.

And then there's the warning from LG, however incoherent (probably just covering their behinds?), which warns to remove the plastic immediately.


I game for 4-5 hours at a time on the TV, and never notice the screen emitting much heat.

Yet—I'm concerned about potential dimming or other damage to the screen that might have occurred due to keeping the film on for so long.
—I wonder if any of you who have left this film on can assuage my fears...who have compared temperature or other metrics to standard.

Thank you,

Here's an odd problem: my time on B7 (when I press Home) is randomly wrong. Sometimes it's an hour ahead, sometimes an hour behind. I have date and time set to auto and have entered my zip code and time zone (los Angeles). Fw 5.80.04

always asked myself - in which way is the tv handling the 12bit signal, having only a native 10bit panel? something like 10bit+frc or is using extra color information for better dithering, eventually using LUT ?

I really need someone to explain to me why I am getting ABL dimming when i watch dark scenes, like for example Ozark. Ozark for those who dont know has a very dark image most of the time and I noticed that my B7 is kicking the ABL during these prolonged dark scenes.

Shouldnt it be the other way around? IE : kicking ABL when the scene is very bright?

It is driving me crazy.

Yeah I regret buying the x700. Were you having player freezes, or just skips during films? I’ve gotten skips on like 40% of the UHDs I have. BRs are fine, but when I buy a UHD I make sure to get one with a code so I can switch when the player acts up. Shame as it works nice with the OLED, and I’ve always been a fan of Sony players.

Thank you,
It won't hurt anything operationally speaking to leave the plastic film on the back. However, there is info somewhere in the LG Knowledge Base where they recommend removing/pealing it off. If you leave it on for an extended period of time, the adhesives may bond to the aluminum and make it difficult to cleanly remove.

There are two reasons the screen dims based on picture content. When there's a very bright section covering a large portion of the screen it'll trigger the brightness limiter. The other is the screen saver that is triggered by what appears to be static content. It doesn't seem to actually detect changing pictures, but instead looks for variations in picture level. If a prolonged scene has just about the same picture level throughout, the TV will think it's a still image, and dim down to protect itself. When the picture level changes enough it comes out of the screen saver mode.

Thanks a lot! Is there a way to disable this? I dont mind dimming in bright scenes so much but the dimming in the case of Ozark makes the series almost unwatchable. It gets extremely dark...

Doesn't sound right to me. I don't get dimming when watching a darkish movie.

In truth I haven't seen the ABL on a bright movie either, maybe I'm just not observant but I don't enjoy watching super bright scenes anyway.

Tbh i never noticed the ABL kicking in in bright scene either. But in dark scenes like watching Ozark for example it happens very often. If you have netflix check it out. The series has often a very dark style and when this happens the tv dims until a bright scene appears (or I force it via pressing a button on the remote to "wake up" the tv).

I've had this happen to me when the screensaver kicks in on my Samsung K8500 UHD Blu-ray player. The jumping around Samsung logo is pretty small, so there are large areas of the screen where it will stay black for several minutes. Eventually, the TV's ABL kicks in and the screensaver gets very dim. Swapping HDMI inputs back and forth makes the TV return to normal brightness.

Although you can turn off ABL using a service remote, I would recommend that you not go down that rabbit hole. Although the dimming action can get annoying, when you play content with super bright images, the ABL will protect your TV from burn-in and image retention. Without ABL it's really easy to overheat the OLED's and damage your TV.

New panel being installed on the 4th. With tech and the live video they both were shocked just how bad the stuck pixel was. Not only a strong white dot, it manifested into a comma like hook next to it. They offered a C8 and even a QF9 yet by accepting that my warranty would be concluded.. So decided for a panel replacement as that would keep my warranty active,. Accidental damage, burn in etc active until 2021. Hope I made the right choice. Anyways LG said these are the latest panels and have the most recent tech in them. So excited this happening so quickly as this crazy stuck pixel is driving me nuts. Anyways just wanted to follow up in case anyone wanted to hear latest details. Have a great one guys.

My new panel (OLED65C7P) was installed yesterday. This is the third panel that has been on this TV, and it is by far the best.

Enjoy. Feedback is welcome.
I’d just like to thank sonoftumble for taking the time to research and post these settings. I have a 65” E7 that I’ve had for almost a year now after coming from a Kuro elite. I liked the technicolor settings out of the box so I didn’t do much tinkering though I did have problems with DV like everyone else until the last update. I have been lurking on these boards for awhile but didn’t want to take the plunge and try these settings until recently when I felt the picture was lacking just a bit. I plugged these in last night and tried a UHD version of fantastic beasts for HDR and some Hulu content for SDR and wow what an improvement, it made an already amazing set that much better, thank you so much.

Hello everyone,

I have a LG B7 and it must be around 2-3 months old. Recently started experiencing an issue where the TV won't turn on.
Sometimes it turns on, but only displays like a black shadow for 1s and then turns off by itself.

Sometimes it is fully able to turn on but after a minute or so some blue pixel glitch thing appears on screen and it turns off. After a few attempts it is fully turned on and functioning for as long as 2-3 movies.

I have tried many solutions like unplugging from socket, holding down power button for 30s etc. Please any help will be appreciated. Thanks!

I think this is an issue with the DV algorithm, it’s still not fully “set”. You may notice this with Haunting if Hill House as well.

Had similar problems, most likely motherboard which fixed it for me. Call LG and hopefully they’ll hook you up, in few weeks !

LG can’t as the necessary hardware are not on the set. Maybe the 2019 will have EArc. This link explains EArc https://www.google.com/amp/s/www.wha...u-need-to-know

I'm not sure the link is entirely correct though. A HDMI device does not actually have to be fully HDMI 2.1 compatible in order to support eARC. My 2017 receiver line was recently updated via new firmware to support eARC for example.


On another note, I am keen to know if anyone has heard any updates regarding the 2160p50 bt.2020 muted colour issues, and if there is any plan for a fix, or is this it? (4.80.04 firmware.....given the 2018 sets are now priority)

The affected firmware hasn't been officially released in Australia, so I don't really have anyone else to blame but myself for jumping the gun and downloading the UK firmware, however, since UK is PAL too, their customers there would have to be pretty annoyed!

I pray I don't have to go down the road of the panel lottery. Glad all finally worked out for you.

So decided for a panel replacement as that would keep my warranty active,. Accidental damage, burn in etc active until 2021. Hope I made the right choice. Anyways LG said these are the latest panels have have have the most recent tech in them. So excited this happening so quickly as this crazy stuck pixel is driving me nuts. Anyways just wanted to follow up in case anyone wanted to hear latest details. Have a great one guys.
My new panel (OLED65C7P) was installed yesterday. This is the third panel that has been on this TV, and it is by far the best.

Hey, browsing through this thread I realized that LG has a new firmware out for my panel (65" B7A). I went into my TV's menu and checked. It's running software version 4.71.00. When I click on the "CHECK FOR UPDATES" button (which I have done in the past as well), it says no updates found. Of course, I have "Allow Automatic Updates" checked but it never seems to do anything. So why is it that the TV isn't updating automatically, and should I just go ahead and do a manual update? I've already downloaded v 05.80.04 from the US server.

C7 here and have watched both seasons of Ozark (great show) and haven't ever seen this behavior. Long shot, but have you turned off power saving features for the TV as that would dim your screen at various times.

I have never been one to shy away from firmware updates, do it all the time for all my devices... yet I have become a bit gunshy after just a few hours after manually doing the latest for my C7 and then developed a odd stuck pixel. My gut tells me it was just a crazy coincidence, yet cant stop wondering on that timing. After my panel is swapped out and passes the mustard, i'm thinking i will leave it up to the "auto update feature" or maybe shut updates off all together. There some out there on Youtube land that think a firmware update is designed to slowly degrade your unit for nefarious reasons... I'm not sure I believe that conspiracy, yet it makes you think. Ok go ahead, tell me im nuts. [IMG class=inlineimg]/forum/images/smilies/eek.gif[/IMG] [IMG class=inlineimg]/forum/images/smilies/biggrin.gif[/IMG]
