To do it by eye, it's quite simple.
Put yourself in a pitch black room, brightness @50, and assuming your low 2-pts are at 0.
Take the blue low, mask the osd the best you can, and watch closely the opposite corner.
Then raise the blue (it's the easiest to spot) until you see a very faint glow. Set it 2 steps lower, and put green and red to the same value (assuming they were the same if the set is calibrated).

On my set, without adjustments, it glows @ brightness 52 OR any RGB low @ +8. My RGB low are now set @ +6, and the results are perfect.

I used the most movie scenes I know to check the results in that department, and it looks exactly like it should. I remember perfectly some of those scenes from my previously owned kuro, and the accuracy to my eyes is the same.
For the record, I think it's the first time I've seen the opening scene of star wars ep7 (the first one with Poe) look right.

You are better off with large scale average adjustments, than with small scale targeted ones that will mess many things up.

BTW : that is if your set is professionnally calibrated and you don't want to mess the cal, touching the 2pt low will only lift the curve at the bottom to where you want it, without needing another go on cal.

I found the 2pt made the tv flash more.

Why would you install 04.10.20? It is basically the same as 04.10.15, with the addition of a fix that solves problems with BBC's player. That's why it's a UK exclusive.

There's always a chance a firmware that's not meant for your TV could cause problems.Most of the time the firmware is wont install if it's not for that TV but if it installs it should work but it's not guaranteed to be perfect & may cause issues

From what I’ve seen on my tv it’s not solved 100%. I would say it’s 80-90% better and does not do it in most scenes anymore. When I changed the 2pt a lot more flashing came back.

Technically when you move 2pts low equally it's the same as moving brightness, it's just much more granular.
It's one of 2 ways to set brightness, and low end gamma.
If this doesn't work, then the tv doesn't work

Just use a test disk, there are many downloadable on this forum and yes some of them are better than what you pay for. Do what you have learned for a few years on here. Turn your Display on let it warm up for at least a hour. Turn off all enhancements and power saver or ECO settings. Set Brightness and Contrast. Leave color and Tint at OEM factory settings ( this means don't alter change or mess with in any way). Try different Gammas and color temps till you find the one you like best For Your EYE'S. Recheck Brightness and Contrast. Now if you have motion problems go thru and see if any of the enhancement Gimmicks and Tricks help you.
Sit Back and Enjoy.

I’ve done a lot of tinkering and my tv looks pretth darn good with the setting as-is. SOME content on HDR still provides an uneven black level uniformity - it has to be a lighter black level, 2018’s Halloween comes to mind with slightly elevated blacks - but moving brightness to 49 resolved that issue.

At this point, Im pretty darn happy with the tv now.

Interstellar comes to mind, the black levels are elevated, and this is how the movie is coded. So no need to alter brightness, it's just like that.

Just so this gets some traction, could people with 04.10.31 check if their "MPEG Noise Reduction" also no longer works? I already reported this to LG support but they are just as incompetent as ever, asking me question that have nothing to do with this instead of just testing/confirming the issue. They also said I was the first to mention this, so if no one else cares, we're gonna be stuck with this being broken.
While I rarely use MPEG Noise Reduction, I would still like to get this fixed.
I checked different sources/inputs/content and it just does not do anything anymore since 04.10.31 not even when set to high, where before medium was enough to get rid of the banding.



This gif should clearly show the difference, look at the color-banding in the sky:

Many people "lurk" and don't post or find these discussions by searches in the future. By having the discussion here, they all benefit too.



For those still struggling here's the 3-step guide to how to adjust your 5% grey level. This was described a few times but here's everything in a single image. Images can't be attached to PMs either.







So. Change the value of (3), if you think you have "black crush" then increase it. Use Wizziwig's excellent test pattern if you would like to. Read the whole of that thread too.

This is incredibly helpful, and thoughtful...thank you for posting this. I adjusted to these on my ISF (Bright and Dark) and Technicolor settings, and applied to all inputs. Without analyzing anything (yet), I figured I would just do this by default, and go from there.

Thanks again!

If it's an android app, it ain't gonna work on iPhone/iPad.

There's a "LG TV Plus" app for iPhone among a lot of other LG-built apps for iPhone ("LG SmartThinQ"), etc.

Can't say if those will offer firmware update though. Perhaps it's time to start looking for the cheapest, used Android tablet you can find.

You missed the part where I said that I get uneven black level uniformity if I leave it at 50. The blacks on the left hand side of my screen appear lighter than on the right. Clicking down to 49 resolves this.

All of Nolan’s films feature elevated blacks 🙂 I should test that out just to make sure they still appear that way to me.

Method...20 Points IRE

IRE....5

Adjusting Luminance....10

I'm assuming these are right for after checking some of the bad "black crush" scenes from the shows 911 and The Enemy Within the black crush is GONE!! I have noticed though on some other scenes that the black background in some shots don't appear to be TRUE BLACK like I remember seeing them before. Is that because they are supposed to be "near black" or should I take my BRIGHTNESS down a notch from 51 back to 50 (the Default Setting for BRIGHTNESS)?
Changing the 5 IRE luminance does not change the absolute black, just the near black on my C8.
So i first increase the brightness in a totally dark room and a total black test picture until I see pixels light up, then decrease it one step until all is black again. After that I adjusted the 5 IRE with the video test pattern posted in this thread until I could see all the rectangles inside the rectangles with a different near black level.

I find this update helped but when a scene comes out of black slowly in a dark room is can still look pretty ugly.

Dumb question time ( and my apologies if this has been asked before), but am I going to gain anything (picture/sound quality wise) by getting an Apple 4K box to stream Netflix, YouTube etc. rather than using the app (Netflix for example) already in the C8?

I noticed the contouring as well jk82. You can see it very well with the opening scene of Game of Thrones season 2 episode 9 using HBO Go app on Apple TV 4k. The Blu-ray version of that scene is clean.

Does anyone know of an email address for LG OLED support, I hate having to talk to any tech support folks. (Yes, it is plugged in to a working outlet.)

Tried the "LG TV Plus" app, doesn't seem to be any firmware update functionality. Just plain ol' remote replacement.

No apologies necessary. Some of these threads can be very long, and maybe a bit contentious at times, so if you're new, just ask away. Connecting the ATV4k to a receiver will allow you to experience HD Audio (Dolby TrueHD, DTS-MA, etc) and lossless Atmos (if you're setup for that). The C8 can only pass 5.1 and lossy Atmos via ARC. Using and optical only passes 5.1. PQ is probably the same but in my experience (and testing) I felt the ATV4k had a better picture.
