That's bad actually; like mine but mine has dark patches in the middle instead of one side. You might or might not notice it in content. Dark panning shots are the most problematic.

Give it time though. It can improve dramatically sometimes. 50-60 hours at least. Then you can try a manual pixel refresh. It didn't help with mine, but I'm Reddit megapost, some people have had dramatic improvements.
Will check around the 100hr mark, might run a manual pixel refresh and see if there is any improvements.

The new Panel that you got, was that from the Retailer or LG?
How did that procedure go?

Photos taken from the YouTube links available in this topic. In 5% gray, I can see a dot in the top(marked in red), but I hope nothing to worry about it.

I haven't replaced mine yet. It's the first only that I got from the retailer.

That dot might be a bad pixel though. It it visible in color slides?
Haven't tested the color slides... Just run through the YouTube links for 5% gray and white. Will check it out with color slides next week... Now away for a week :(.

If it's bad pixel, something to worry about?

How do you like the PQ over the frame!
Obviously oled will be better right :D. Frame cannot be compared with oled at all.

I know, right? OLED just blows away VA panels for me too.

Anyway, if it's a bad pixel, contact LG. They might ask you to run the manual pixel refresher multiple times. If that doesn't help, then take a new set. This one is obviously defective then.

Please see my shots, is it too bad, should I try my luck with LG for panel replacement?Screenshot_20191129-224153_Gallery.jpgScreenshot_20191129-224145_Gallery.jpg

Seems about average. You might have to go for 2-3 changes to get a better one.
If you may see the pics closely there are two prominent white bands, is it normal for an average display?

How many hours in is it? I have seen 3 panels now and they have all undergone changes in a short span of time . I think you should be ok with the one you have as Marakk put it
About 100 hours, the other panels you saw, did they also have prominent white bands like can be seen in my pics?

They did have banding . The bands were not as intense at the time of using the grayscale slides but I remember them being there when I first got the sets.. other than the bands I had other issues. One was a circular patch on the left side . This was on the Panasonic FZ950. Also I had a darker tinge to the left side of the same panel. Both the issues sorted themselves out, the first within 24 hours after the maintenance cycle kicked in and the second a few days later. But there was a black line within the same time frame due to which I returned the unit. The C9 too was similar but it was a demo unit that had finished 112 hours at the time I did the test. That had the same blotchy look and bands. However the appearance of the bands seemed to change, the blotchy look not so much.

Is this noticeable when watching specific types of low nit content as well?

@Marakk @Gfreeman thank you guys for your inputs.

Attaching better captured 5,10,20% pics.

As we know that our consumer protection laws/ rights are nowhere as strong as those in Europe, i don't think LG India will agree to replace the TV itself, at best they may agree to change the panel after lots of persuasion.

Wanted advice from you guys as to whether its worth the hassle to persuade LG to replace my panel?

@Marakk is the uniformity issue with your panel resolved, did you got your TV/ panel replaced?Five Percent.jpgTen percent.jpgTwenty percent.jpg

Nope. It has just improved slightly. I have gotten a phone with bad tinting replace from Vivo. The next one had only slight tinting, but grey uniformity was still not perfect. After seen about 6 OLED phone screens and 2 OLED TVs in person, I haven't even gotten one good or close to good panel. I don't think it's worth the hassle to replace the panel for me. No guarantee that the next will be better. Unless yours is so bad that it comes up in content watching frequently, I wouldn't bother. Your opinion might vary. Decide for yourself.

Hmm, it seems to depend on manufacturers, my note 10+ has absolute perfect uniformity with zero banding. In future if samsung manufacturers OLED TV, i believe they would have much better QC.

My cousin's Note 10 doesn't. My brother's A Galaxy A8 doesn't. Forums are full with people without adequate dark uniformity. Have you checked in a pitch black room? In phones it often doesn't present itself. Both my bros hasn't even noticed it yet. Smaller panels have better odds of uniformity though. Imagine your panel cut in smaller pieces for phones. Half of them might have good uniformity when cut in smaller pieces. Anyway, my point is that chances that you'll get a better TV are low. LG is going whatever it can. There's a tech for great uniformity but it requires custom tuning of each panel. Only GZ2000 seems to be employing that as of yet.

Yes i have checked in pitch black room, absolute perfect uniformity.

But you are right, it's easier to have a uniform 6.8 inch oled phone than a 55 inch oled tv. But I still believe samsung has better quality control than LG, shame they don't make OLED TV.

They did for a short while, and they'll be making them in a few years again. So you might just get your wish.
