I have similar issues with 4K Directv channels. Although it may be the hardware, I have raised the issue with Directv. Seems a firmware fix is in the works, but would not hold your breath. My Sat. box goes through my AVR first, so the quality of HDMI cables is critical. I have new cables on the way which should help solve my problem to some degree. Together, with the firmware upgrade, I hopefully will not have any more issues. Streaming is much more robust, since no cables involved, never have problems there.

Beside, for the most part free 4K Directv programs really suck. And there premium 4K pay channels are way to expensive compared to same programs over the internet. Not expecting much from them until networks upgrade their 720P cameras. Ypu would think the networks would move a little quicker on that with practically all TVs now sold 4K and Netflix and Amazon stealing their viewers.

Sorry, got way off topic here.

Don't watch CNN and I've never had any dimming issues so I'm good without messin' in the SM.

I'm not a fan of TruMotion so I have always left it disabled on both of my LG's, and have not had any issues with fires/candles.

When the compensation cycle doesn't run, my media light, plugged into the USB port turns off about a second or two after the screen goes dark. When the compensation cycle runs, the power to the USB port is still there as the cycle runs and the media light stays on until it finishes. That's how I tell a cycle is running. So to answer your question, shutting off power triggers the compensation cycle if it has been at least 4 hours of watching since the last cycle.

Try unplugging the TV for a few minutes maybe 10 minutes 15 minutes and see if that resets and opens up the white balance option

As someone else said, it's the cumulative wear on the pixels (i.e., the excessive use of red on CNN persistent logos). LG has made changes (like increasing the red subpixel size, etc.) to try to mitigate it. But, having already replaced an EF9500 precisely due to CNN logos burning in, I don't trust that it can't happen again - if I watch CNN etc. for any appreciable length of time on my C8, I use Live Zoom to get rid of the graphics.

Thanks! I figured it had to be something like that but wanted to make sure it was some kind of common issue with LG OLEDs and not just a faulty board or panel. Hopefully an update will fix. I used to be totally against any kind of motion handling but have been using it more as of late. Guess its back to the “old fashioned” viewing experience for the time being. Lol. Anyway, thanks again for the insight. Other than that issue this thing is about as close to perfect as I’m gonna get. I love it.

If I have a burning need to watch CNN, or anything else with a persistent logo, I'll just go downstairs and watch it on the LCD.

Sounds Like a handshake issue. I have had none of those issues.

FWIW, the STB Power button on the remote, the upper right button, is Set Top Box Power, not standby power. The power button on the upper left puts the set into standby.

Merry Christmas and Happy Holidays all! Haven't posted in awhile again...

Quick question for those with the dreaded near black macroblocking issue - may seem obvious, but have you tried doing a factory reset on the TV?

I ask because when I was working to autocal my TV, I messed up settings quite often or used the wrong patterns, etc and I was able to re-create what folks are seeing by mistake. A full DDC reset of the TV or factory reset of the TV brought things back to normal.

Factory reset might not fix it for some if lets say there is a problem with your factory calibration tables. But full DDC reset would bypass those calibration tables.

Full DDC reset is only available (as far as I know) using Calman, so if you don't own the software you probably cannot do it. Full DDC reset uses the TV without any kind of calibration tables (the factory calibration) and makes the TV have a very blueish hue to it (at least on mine). You probably wouldn't want to keep the TV like this, but if you have the macroblocking issue and you have Calman, it might be worth a shot to try the Full DDC reset?

I saw the effect with both factory default luts and post-ddc reset luts created from a calman calibration. But the latter looked vastly better with fewer flashes (still some) in content. Jk82's excellent test squares showed it in both cases.

I have done a full factory reset too, to get the new technicolour LG lut and whitepoint (I foolishly choose that mode to overwrite with my own lut!). I don't think it was a panacea however I do think that any calibration (with the calman lut uploaded) does help somewhat.

I’m still half debating calling the store first thing tomorrow morning and telling them to send me an LCD instead, and just deal with whatever uniformity issues I get. I appreciate those that have told me that I have nothing to worry about because not everyone is affected but it seems a lot of people are, even for a community such as this.

How many of you do not have this issue at all? How many of you had the problem day 1 versus getting it later down the line?

Logic tells me that most every website called the C8 their TV of the year, and that there would have to be a significantly larger uproar if this was a super, super wide problem. But the fact that both Vincent and John Archer have seen the problem on their sets is definitely worrisome for someone about to accept delivery.

Sorry if I’ve been occasionally been a pain but, I’ve been through multiple sets since September and feel like I’m stuck between a rock and a hard place between how LCD’s can get issues just from mass production and even shipping, and this potential issue with the C8. I’ve mentioned it before but I will NOT be able to return this one if there’s an issue. That means that even if I get what’s bad banding to my eyes, I have to deal with it.

But OLED’s PQ is certainly tempting...

Hey, ya'll.

Trying to decide between something on my C8 because I've become obsessive with this: Proper brightness levels. I've come off of using a x930e from last year so the shift in brightness capabilities has been difficult.

Should I use Dynamic Tone Mapping (despite being conflicted whether it's "accurate" and "artificial" or not, as said by Rtings.com) or buy an HD Fury Linker to reach more appropriate brightness to match in-game HDR Brightness tests (Battlefield, Resident Evil, etc.) for HDR gaming?

I don't want to use DTM if it isn't creating an enhancement of the intended picture. Am I wrong or thinking too much about this? I've already been told I've gotten the wrong impression of DTM by considering a Fury Linker and don't want to waste any money. I want games to look as if I'm looking at a more realistic, bright contrast from lighting again like I received from my Bravia, as close as physically possible by the C8 (without sacrificing everything else.)

Thank you!

Mine has had it since day one. Yours may not have this issue at all (or any issues), but if it does, I feel very confident now that a fix will come. So don't let this issue be the deciding factor :-)

Thanks for the opinion.

How much does this issue actually rear its ugly head in actual regular usage? Let’s say I’m watching a film that’s fairly dark overall...can I expect the bad blockong throughout, or will this only affect a very very very small sample of the film?

^^ The quest for the Holy Grail leads only to a mirage and the C8 is just one more illusion. There's only been negligible advancement of technological perfection that can soothe the savage beast better than the Victrola. Except perhaps Zanax. But that is discussed in another thread somewhere.

We watched the Muppets Christmas Carole last night (I can't help it, I love muppet movies ) which has lots of black/gray scenes, fireplaces, etc and it was pretty much dead-on-balls perfect with no dimming, macro blocking (or whatever the term is for the current issue) at all. Haven't seen it on other sources either. Looking forward to watching Fantastic Beasts and Where to Find Them in 4k UHD later on.

I never trust an atom, they make up everything.

A big factor is the quality of the source.

If you watch 4K contents you may never see the issue.

I’m currently watching la Casa de papel on Netflix and the dark scenes just look horrendous.

I have done a full factory reset too, to get the new technicolour LG lut and whitepoint (I foolishly choose that mode to overwrite with my own lut!). I don't think it was a panacea however I do think that any calibration (with the calman lut uploaded) does help somewhat.
Oh well, thought maybe it might help I have definitely seen really bad macroblocking issues, but it was a result of a bad calibration that was fixed when I did a full DDC reset and then either a proper 3D LUT Autocal or just running a test after the full DDC reset with no LUT tables.

I've been lucky (so far) - I tried the test squares and didn't have any flashing or anything out of the ordinary on my set (the ones I downloaded were the ones linked in John Archer's Forbes article published on 12/24/18 - assuming those are Jk82's?). Not sure if I'm just lucky or maybe because I have an early set (built in March or April of 2018 I think?) - but *knock on wood* I have over 1000 hours on my set now and no issues, my near black uniformity has also been good.

Hard to say really. Just because one scene causes the near-black flashing doesn't mean that another very similar looking scene does too.

Take a look the the two attached screenshots of vikings. The first one is the original which does cause flashing artifacts on my C8 and the second one has been slightly modified via a shader and causes zero flashing.
They look very similar, don't they? So very minor differences can make a scene show the flashing issue or not.
