I’d check but I have not received the update yet?


It’s on Web OS 3. LG will not update the Web OS on 2017 sets. Webos 4 is for 2018 sets and Webos 5 will be for the upcoming 2019 sets

Anyone notice the 05.80.15 update from the US and the Korean web sites are different sizes?

Korean 859,793 KB
US 858,918 KB

Anyone have any idea what the difference is?

Nevermind, I'm an idiot, it just pulled the vizio again for some reason, happens through a fire device. The other user I read must have just bought a fire device and hooked it up to their set and saw the same thing I did, coincidentally on the same day.

The whole thing with ASBL kicking in and dimming the screen when there are dark scenes in a movie/series has become unbearable...

First Ozark , now the Haunting Hill, these shows are pretty much unwatchable on my OLED due to the stupid ASBL kicking in the entire time.

I refuse to believe that in the year 2018 LG hasnt found a way to make the TV understand that a moving picture, however dark it is, is not the same as an idle screen...

I mean what the hell is this and why dont i see a lot of people complain about this? How is this acceptable?

The tv is amazing but for the past 3 weeks i havent enjoyed watching a lot of dark content in it.

I am frankly tempted to try and disable the ASBL through the service menu but i dont know what kind of other repercussions there might be...

LG needs to patch this thing immediately....

Well that’s what I thought, but then folks are saying they saw Alexa support which was part of webOS 4.0 so I’m a little confused .

might have something to do with the "translation" - the native language posted of their has to be translated to English so we can read it

LG OLED 77G7P - Panasonic TC-P65ZT60 – OPPO UDP-203/103D - Toshiba HD-DVD-3A – Harmony ONE
Marantz SR7011 - Definitive Technology - Studio Monitor 65 (2) - CS8040HD - Studio Monitor 55 (2) - Super Cube 6000

False alarm. The reason for the difference in file size can be attributed to the installation instructions in the Korean download that is not contained in the US download.

Interesting. My "All Settings -> Accessibility -> TV Power Sound" has always been set to "On", but I never heard the three "On/Off" sounds at all. Immediately after reading the post, I turned "TV Power Sound" "Off" and then "On" again - and now I do hear those three "On/Off" sounds. Luckily, I rather like them - at least for now.

What B7 functions can be controlled through Alexa - and anyone know if any B7 functions can be controlled through Google Home Mini?

You'd need to pair Alexa with a harmony, not sure whether google home can interact with Harmony but if it can, I highly recommend it.

This is not a common problem which would explain why there's very few complaints. I've only seen this happen when my Samsung Blu-ray player's screensaver was going - and then it was only after 10 minutes of a mostly black static screen. Never noticed any of this with active content - regardless of how dark some of the scenes might be. Are you certain that you don't have some level of Energy Saving turned on? I really can't think of anything else that might cause this behavior.

EDIT: Maybe the ambient light auto-dimming feature is turned on?

All energy save options that i know of are off. What is this ambient light auto dimming feature? Where can i find it in the settings?!

I am using your settings by the way. Have you tried watching Ozark or Haunted Hill? You get no dimming watching these?

With all due respect, it is absolutely more common than you may think, especially with a lot of recent Netflix Dolby Vision contet that is inherently dark. Hill House and Sabrina are particularly bad.

It has become VERY common on Netflix DV content.

Haunting of Hill House - Check
The Ballad of Buster Scruggs - Check (last scene towards the end)
Maniac - Check

I think one of the recent firmware "upgrades" caused to ABSL to become more aggressive. I never noticed it and then 2-3 months ago starting seeing it far more often than before.

No, it’s very common. I notice on the same shows as well as things like The Ranch, and in video games.

I'm out of town and not in front of my C7 to provide the exact name of the setting, but there is one that will basically auto-adjust the OLED LIGHT based on room lighting levels.

When I first started hearing about how dark Hill House was - that's what prompted me to recalibrate DV to flatten out the gamma response. However, tone mapping still has a tendency to get in the way no matter how aggressive I get with the 20 point settings.

OK - I stand corrected. However, the purpose of ABSL is to protect the TV and prevent OLED overheating. It really shouldn't be kicking in with dark scenes as they will not be the cause of that issue.

I'll take a closer look when I get back home.

All, my C7 is driving me nuts.

It displays channel number (or input e.g. HDMI 1) and time constantly in the upper right corner.

No remote button, nor Menu option seems able to make this go away...

Has anyone else encountered this issue and know a workaround?

Glad to see there is nothing wrong with my tv, i spend last night googling about it but you guys just confirm the issue.

Yes netflix and dolby vision lately has become a pain to watch... i seriously think LG needs to address this asap.

I was about to do a factory reset but i guess it would be a waste of my time. It simply is an issue and i dont know the kind of “leverage” avsforum can put on LG to address the issue.

I too dont remember noticing the issue as often as i lately do. Dont know if a firmware update messed things up but lately i just cant deal with it anymore. I tried watching a scene in Haunting Hill in HDR (not dolby vision) and i can confirm that ASBL doesnt engage as often as it does with DV. It still does, but not as often.

I honestly do believe that this issue is very important and should have its own thread. This really NEEDS to be fixed. A lot of netflix and amazon shows are “dark” and the ASBL thing destroys them.

When my c7 was new 2 years ago I saw this too, then I turned off energy savings and eye comfort (in each picture mode) and power savings (general) and it has not happened since.

Here's a couple videos where you can see the panel brightness return to its normal level when I bring up the settings menu.

Exactly. This really needs to be fixed. I am not very active in this board but if there are people who have contacts inside LG a heads up to them, would really be appreciated.

Those example scenes are not all that dim, so I'm thinking that there is either a corrupted configuration file, or a processor board that has lost it's marbles.

Has everyone who is dealing with this behavior performed a full factory reset? Not just a picture mode reset, but the whole enchilada reset?

EDIT: A corrupted config file will prevent you from actually changing a particular setting under the hood, even though you can make a change in a menu visually. Something to try. Experts will recommend that whenever a FW update is installed - regardless of brand - you should do a full factory reset. The factory reset will force the TV's OS to build all new/fresh config files.

EDIT 2: I watched "A Quiet Place" (DV) the other night. Lot's of dark scenes as a movie like that should have - No strange dimming behavior.

No, it’s just the TV’s ASBL kicking in. It’s no coincidence we’re all experiencing the same problem with the same shows.

Disabling ASBL in the service menu gets rid of the problem.

I had a similar problem with the dimming of the screen, or I should say, constant changing of 'oled light.'


I was watching Blade Runner 2049 in HDR, with dynamic contrast set to off (oled light 100), and then decided to give some boost in brightness (it was quite dim even in daylight scenes) so I put DC to low - the screen increased the brighness a little and then went back to initial, then I put the DC to off and the brightness remained the same.



Then I turned off the tv (B7) and turned it on again, continued the movie, set DC from off to low again - and the screen went brighter and remained that way. BUT - in every scene I experienced this dimming or brightness changing, even in the static scenes like at the end of the movie where K and Deckard walk in the snow, you could see the snow getting brighter then dimmer on repeat.
