      It's not that easy to state: the issue mostly depends on your and others' settings.

      I don't believe there are settings that can fix that issue, that is why I was curious on firmware differences. I have my settings as www.rtings.com/tv/reviews/lg/b8-oled , but I tried adjusting everything with no effect, that fade-in looks terrible regardless, while on my cheap LED TV it looks good/normal. And I see this exact issue during certain dark scenes in movies as well, not often but noticeable (including that Vikings scene).

      Yes, I can confirm that quad step noise reduction works on both 05.10.00 and 05.20.00 (engineering mode) - and the crushed blacks have also been fixed (gamma the same as on 04.10.20).

      Me neither, but different settings can hide and trigger different anomalies. I can check it on mine this evening (I use 3dlut, only the white point and oled light were modified on the TV), but I could see macroblocks in the current ep.3 of Game of Thrones, so I'm not sure what's the point of this test, since we know the macroblocking is present with earlier firmwares.

      Yes. JK82's 9-square test is the "gold standard" test. Before that was created we had all sorts of hassle pinpointing clips from various sources.

      Also we have no hard proof yet that any firmware for the B8 model has addressed the problem on that model.

      For @wwwww, I have checked that YT clip on my C8 with the C8's .55 firmware and have no issues. But this is because it's my panel, and my panel's black level (down to panel variances in the hardware),etc. As explained by Vincent 6 months ago in videos posted to this thread.

      ps. Beautiful music, and a very controversial track since it's the only one in the entire series to use the piano (a modern instrument) - everything else uses medieval-esque era instruments :) . If that piques your interest I recommend:

      This clip shows the colour gradient banding I get on my b8. I'm really interested to know if anyone else gets this gradient banding issue with their OLED TV? Top left quarter of the screen shows it the most.

      Game of Thrones: Season 6 OST - Light of the...

      First 5 seconds of fade here ^

      I didn't know that sorry, I'm new on this thread. Just gonna have to wait for a new firmware release then. Hope they move quick, as I still have 20 days to return it, which will probably do if they don't fix it by then... :(

      "Owners of LG’s older B8 OLED TVs will have to wait a little longer however, as the company has prioritised the firmware upgrade for TVs using its Alpha 9 processor. However, Archer said the update for the Alpha 7 chip is almost complete and should also be released soon." - hdtvtest. co.uk/n/LG-Plans-Firmware-Upgrade-to-Fix-Flashing-and-Noise-Issues

      Although I'm new in the OLED world, but I - respectfully - disagree :)
      What do we call "hard proof"? :) That LG writes it down in the changelog? If so, then you're right. Otherwise I'm pretty sure that the crushed black of v*.65 came from the "fix" of C8 , otherwise where else? (And thanks for the table you have put together :) ).

      No worries, I didn't know that.

      I'm 99.99% sure that we won't receive the "final fix" within 20 days :) And just to know, the new C9 also suffers from this, although they state not that much. So, they won't be able to completely fix it, even with the "final fix".
      But honestly, for me the tint is way bigger issue (if I'd have to rank them).

      Yes that's the level of proof to which I was referring. Everyone is free to disagree I'm only one bloke! Otherwise all we have is speculation. Sometimes it's logical and reasonable, other times it's wild. I like to remove doubt.

      It does make sense, I agree :) And you're welcome! :)

      Firstly, no-one has ever said that the next version (5.10.00 / 5.20.00 currently in testing) is the "final" fix. There could even be a 5.30 and 5.40 before they make anything actually public and release it! This is based on the idea that no-one knows what on Earth changed between 5.10 and 5.20.

      You are quoting it as if it came from someone, or perhaps it's just a turn of phrase? As far as I am concerned it's just the next attempt on the road, and nothing more than that. If you have a quote from LG's engineers saying "that's it, we can do no more, and we are giving up" then please share it - otherwise it's a case of waiting to see what they do. :)

      Secondly, notwithstanding what I said above, I hope we do get the next version pretty soon, it ought to be within 20 days from now, and it may (I hope) make @wwwwww happy enough to keep his TV. All without it necessarily being "final". If that makes sense.

      In the next 20days in the UK? The UK website support page shows .55 yet there is so much talk of .65. Very confusing.

      See LG UK Support screen shot below for LG OLED65E8;

      I think the .65 refers to the B8, not the C8

      Ok, that is conflating two completely different topics here.
      I am talking about the C8/E8/W8 firmware.
      2019-recent-firmwares.png
      There's now a 5.20.00 as well. We're hoping that it will finish testing and be released soon for those models. We don't know what version number it will be.

      Completely separate, there is a firmware set for the B8 models, which have a different chipset. Those versions are nothing to do with the table above. There is a version for the B8 which ends in "65" (co-incidence only), which has a similar "crush" effect to some of the C8/E8/W8 firmware we've seen recently.

      HTH

      Looks like once we update to 5.10.xx we can officially start moaning about missing eARC and Airplay lol.

      My 65"C8 auto updated to the dreaded .55 Firmware automatically last week (Been loving the screen since late November on .20 Firmware.
      Just to say after reading comments on here on how to possibly roll back the Firmware via Smartify on ios/iphone,
      I prepared a USB stick with the .20 Firmware and viola via apps button in the smartify app, highlighted software update which brings up hidden expert Firmware Downgrade.
      Overthemoon!! Again, the screen looks Superb again.
      Wifi turned off for now just to be safe.

      Didnt want to wait for the Newer Firmware, could be waiting months.

      Indeed, except anyone moaning about missing eARC might as well moan about "missing 8K" and "missing 12bit panel". The chipset can't do it otherwise we would have had it from launch, just like the 2018 Samsungs had ALLM from launch. HTH :)

      Thats cool you like it, but imo, its just a darkened picture that also seems to make colours a tad darker, just watching A few good men 4k Disc thru my Panasonic ub820. Cant imagine how could look any better even after a pro Calibration.
      Absolutely stunning looking print, Defo one of the best catalogue remasters from Sony.

      To be honest with you it doesn't look much different, it's just that the blacks look better with no sparkles.

      It was just a phrase to make what I said clear.
      @wwwwww has a B8, there's no chance that that new update will arrive in 19 days to B8 since C8 hasn't got it yet :)

      Just to add with regards to the Game of Thrones macroblocking issues people were seeing on the LG B8. I changed TV to the Panasonic FZ952, and re watched the same episode. Huge improvement. The episode looked excellent. On the B8 it was almost unwatchable with large black blocks on screen

      B8 owner here and I was wondering how certain it is that this model will receive a fix?
      Should I try to contact my retailer and upgrade to a C8 to be sure?

      Yes, but only in the beta. It’s not public yet (although I have been using the beta for a little while now).
