Just before Christmas I posted a story about a couple of major picture problems that were reported across the globe by owners of all models of LG’s 2018 OLED TVs.

One issue involved a strange flashing effect with near-black content – particularly apparent during fades to or old t of black. The other was exaggerated noise during very dark scenes – particularly (not exclusively) with streamed content.

Back before Christmas, there was concern that the problems were caused by some sort of hardware failure, since there did not seem to be a discernible pattern when they started to appear on different 2018 LG OLED models. 19659008] LG has developed a firmware update that pretty much completely fixes flashing and blocking issues experienced with 2018 LG OLED models – including the pictured C8 series.

I’m happy to report today, though, that LG has lived up to the promise of the CES in January by creating a firmware update that tackles both problems.

LG has shown me the new firmware (currently version number 04.10.31 , though this could vary by region ) Working on 55-inch and 65-inch C8 models, and I can confirm that it blocks the blocky, gray ‘wash’ and strange posterization issues that were so aggressively visible before. Season 5, Part 2, Episode 12 on Amazon Prime Video.

The noise hasn ‘ t completely vanished. But it seems so much more rarely and is so much more than it was before the new firmware was applied that you hardly ever notice it. Particularly if you use the standard picture preset. In fact, any residual noise is more common in Amazon than anything with the TVs.

Just make sure you turn off the Eco picture settings if you’re using the standard mode, otherwise you can experience some black crush in dark areas

The Last Kingdom at 21:30 into episode eight of season three now appears with scarcely a trace of the old pulsing effect.

LG tells me that the solution to both the flashing and elevated noise issues involved adjusting the near black management of its picture processing engine.

While this is all great news for owners of 2018 LG OLED TVs, though, LG confirmed that its solution is specific to LG’s processing, it won’t work with other brands of OLED TV experiencing similar issues. Each brand will have its own fixes through updates to its own video processing engines.

Similar issues seem to affect Sony’s A9F TVs. But since LG’s fix is ​​specific to its own video processing system, Sony will have to try its own separate firmware fix. Photo: Sony

Sony 2018 OLED TVs in particular seem to have the same kind of problems. In fact, I saw the issues for myself recently on 65A9F – and having pointed them out to Sony, the brand has now acknowledged to me that there is indeed an issue. It is currently working on a solution.

There are reports of similar but less aggressive issues on some Philips (Europe) OLED TVs, too.

LG tells me that the firmware update that fixes the issues on LG’s 2018 OLED models is essentially finalized already, and so is expected to start rolling out to C8, E8, W8 and G8 models by early April at the latest. The US and Europe will probably get the update first, with other territories following shortly after.

If you own one of LG’s B8 OLED sets, you will have to wait a little longer for your update to arrive. This is because LG has prioritized the update for models that use its Alpha 9 chipset (since there are more of them).

I’m assured, though, that the update for the B8’s Alpha 7 chipset is already up and running in LG’s labs, and so shouldn’t be too far behind the Alpha 9 update.

While it would obviously have been preferable if the issues (the exact causes of which remain unclear) are addressed by LG’s new firmware fix had been shown up in the first place, LG certainly deserves credit for the seemingly substantial amount of effort it’s put into fixing them. And in case you’re wondering, LG assures me that such issues should affect its imminent new 2019 OLED range .

Feel free to let me know via my Twitter account below when the update arrives on your 2018 LG OLED set

Just before Christmas I posted a story about a couple of major picture problems that were reported across the globe by owners of all models of LG’s 2018 OLED TVs.

One issue involved with strange flashing effect with near-black content – particularly apparent during fades to or out of black. The other was exaggerated noise during very dark scenes – particularly (not exclusively) with streamed content.

In fact, I was able to confirm the existence of both these issues myself, on an OLED 55B8 I had in my test room
