Thank you. Yeah I did notice a PQ improvement on my 55" C7 after I have been watching for a few weeks.

There's no issue using a PC on an OLED, specifically for games and TV shows/movies. Quite a few people use them for that, including me. The majority of video content I watch is through the PC, and all multiplat "AAA" games that I end up with are on PC also. As a replacement for a typical desktop scenario though? I know some people do that, but those are fringe scenarios.

AFAIK, the cycle is after 2000 hours, and when people are saying 100 - 200 hours, they are just talking about your set aging as well as having let it run its multiple 10 minute cycles that happen every four hours of content. You can force the 2000 hour one by just running it manually though.

I am still following this thread since about 200 - 250 pages ago when I first got my 77c8. Thanks again to the experts and experienced users who post here. I really appreciate the info. I have very much been enjoying (and appreciating) the firmware discussions and info. And, I am actually not burnt out on the FW posts as I am still on .15 waiting for things to shake out. My panel does indeed exhibit chrominance overshoot (flashing, black macroblocking, Gail Gadot) on some near-black content but everything else about the panel is amazingly great. I appreciate that LG continues to work on a new FW that will improve this.

It is interesting to me that the overall PQ improves so much during/after the first 200 hours of use. I definitely observed this with my panel and I wonder why this happens.

I do have a couple of questions:

What is the difference between the comp cycle (auto run every 4 hours when TV turned off) and the pixel refresher cycle (auto run every 2000 hours or manual)? I am wondering what the control electronics is doing and what is chemically being performed on the individual pixels.

I came from a C7 where I can confirm that the ANSD were not present.

And why did they have to make the screen get brighter when it wakes up with "stutters/pulses". I have counted up to 20 such "chops/stutters/pulses" before the screen is 100% bright again.

I'm so annoyed... using a computer on this TV is going to make me want to throw a rock through it!!!

One strange thing though... when using Aerial screensaver (the same as on the Apple TV) on a W10 PC, the ANSD dims the panel when the Aerial Scr don't have bright pictures.
Is this because the TV detect the screensaver as a static picture, and not a moving video??
I've used the C8 for about a year now as a PC monitor, and even with TPC disabled in the service menu I experienced the same behavior.
But strangely enough this happens only in SDR mode. If you enable HDR in Windows and disable dynamic tone mapping, the gradually dimming and brightening again in those steps is over. Using HDR on the desktop in Windows looks great in my opinion, it's not washed out or too dim (there's a slider too make SDR content brighter).
Yes, the OLED light is at 100 constantly, but it's all about the perceived brightness. I've measured the power usage and it's about the same in comparison with SDR and equal brightness.
To this date I have not had any image retention let alone burn in. The set has over 1800 hours on it.

I have a 65 C8 that has the noticeable dimming also that I had posted about a few weeks ago. This happens with live baseball games for example that has little movement or changing scenes. Haven't noticed it with movies. I believe it was designed to work with static images only to prevent burn in but it reality it doesn't function as designed. It was so bad watching a web live stream of a college baseball game with a stationary camera that I had to bring up the TV's menu about every 5 minutes to make the picture brighten up temporarily till the cycle starts again. I'm on the .55 firmware now ( from the .31), I didn't notice it as much when I was on .15 or earlier. I'm hoping a new update will help it be less noticeable but now that so I'm aware of it.... This is a VERY annoying 'feature' that needs to be eliminated or I won't be buying another. Please contact LG as I've done, maybe if enough complaints are made something will be done about it.

That is one of the more frustrating issues for some 65 C8 owners. I've had mine since October and never had the dimming issue on baseball/basketball or any other live sports as well as movies from any source. I'm still on the .15 firmware.

I never trust an atom, they make up everything.

I am not sure how long the image needs to remain static for the dimming to kick in. I have only noticed it a couple of times when I am on my computer and I forget and walk out of the room for a while with the computer image still displayed. When I returned I noticed that it has dimmed. I am always very thankful for that feature as I should remember not to leave it on a static image but forget sometimes.

^Yeah that's the only dimming I have ever noticed on any of my OLEDS ever. Never during any actual content.

https://www.avsforum.com/forum/40-ol...l#post58001060
At first I spotted it in normal SDR Game mode and found that it goes away in Cinema-like picture modes. But I usually use SDR in PC mode (I am lazy to switch back to the HDMI label for SDR movies) and it's present in the ISF modes there. So this seems to be tied to the low latency modes in general rather than the Game preset specifically.
I never noticed this on the C7. Actually, all-in-all, I think I had less issues with the C7 than the C8. The under-saturation / color luminanc errors were apparent in the SDR range in HDR modes. But otherwise there was no random heavy dimming and elliptic artifact in Game and PC modes. And even though AutoCAL is a plus, if I am realistic, the factory calibration was decent on both .... before the macro-block update (which introduced the gamma drift on the C8) and I barely get to use the BFI (since the HDR curve can't be adjusted for the reduced brightness and it causes 2:3 judder with 24fps movies, so it's pretty much limited to SDR games where native 120fps is not more favorable than the 4k resolution).

Yeah it is frustrating. I know it is very apparent on my TV when watching NBC sports Phila. during baseball telecasts. I'm hoping the new firmware improves this maybe somehow the dark gamma with the last updates is tripping this. I was seriously going to look into a 77" in the near future but I'm a little concerned about it as it's enough of an issue for me to rule out a another OLED that does this. Waiting for the new firmware to come out to see if it helps. Hopefully soon.

Just an observation. Been watching my new 77" C8 today. First time I have the time to sit and view.
Watching Netflix's "Godless" with DV and "Blacklist", both 4K and the PQ is beautiful. Rich and silky.

Have it on 'Standard' and I might be changing that but wow it looks so good now.


Coming from Samsung 82" Q8FN and was worried the C8 wouldn't have the punch the Q8 does. No reason to have worried, it's bright enough.
Got a little SOE I have to get rid off so will be playing more with the motion settings.
No buyers regret.

It has full Dolby Atmos (and DTS:X), and is supposed to go down to 30 hz (though I doubt this, with 4” drivers), in any case, it has a sub out if the bass is not to my satisfaction. (The cost doesn’t really bother me, since the sale of my other gear will more than cover it), but I mention this as another good option for those who don’t have the space (or inclination) for a full blown HT and still want good sound from their LG display.

Sweet! I think the Senheiser would still be too much for my small apartment. I do not think I'll ever turn up the volume enough on even my Bose setup to appreciate it's true worth. I had it the loudest yet the other day watching an Ian Anderson/Jethro Tull in Montreal blu-ray. It was terrific. And again last night watching the Warriors unfortunately go down to the Raptors 0-1. I'm expecting to hear some complaints if I keep it up.

But I look forward to hearing of your results with the Senheiser. Do you know the approximate availability? It's only available for pre-order right now, correct?

You should really used Technicolor, isf bright and / or isf dark mode. They are the most accurate. Standard isn't that great

The times I see any dimming at all is also only when I am in PC mode using my iMac mini and the image remains static while I am reading something for more than 6 min or more. The dimming stops when I move the cursor around on my 77" C8. I am on FW .55 and using ISF Expert (Dark Room) PM with the suggested settings for IRE and Luninace from @chronitis and @jk82 . OLEd light at 28, etc. It's a bit jarring or annoying but not intolerable. I expect it will go away with the next FW update.

I had thought I was "patiently waiting" but now, like you, I am "IMpatiently waiting!" One would think it would have gone through their "quality control process" by now, especially since some users, who accessed the Service Menu and downloaded it, have had no problems with it. The longer I wait the more leery I become.

The most important thing is, the Bose is working well for you. Satisfaction is a precious commodity! Enjoy!
The Sennheiser Ambeo soundbar is available for pre order (i already put mine in), and is due to ship on June 12. It may well be overkill for many applications (and the $2500 price tag will make it out of reach for some), but if the buzz on this is correct, it could be a game changer. Coming from a full-blown, 4 ceiling full-range, 7.4 dual 18” subwoofer system, I’m hoping to get at least a reasonable facsimile of the former glory my system allowed me to experience. I’m hoping it will be a worthy match for my 77” OLED and I will mention it here briefly, but I do want to be considerate of the other OLED owners who may not have an interest in this, and there is a dedicated thread for this product.

You should be pleased when it does arrive. I used my Harmony Hub to change to Engineering mode to get 05.20.00 and I think it will make everyone happy. I was one of those that didn't see much if any black crush with .31 or .55. I am pleased that with the latest beta firmware as my set doesn't look "lighter" in low IRE's for the lack of a better term. Everything tests out just the same for me. But the only way to truly test poor gamma is with the proper calibration tools.

But strangely enough this happens only in SDR mode. If you enable HDR in Windows and disable dynamic tone mapping, the gradually dimming and brightening again in those steps is over. Using HDR on the desktop in Windows looks great in my opinion, it's not washed out or too dim (there's a slider too make SDR content brighter).
Yes, the OLED light is at 100 constantly, but it's all about the perceived brightness. I've measured the power usage and it's about the same in comparison with SDR and equal brightness.
To this date I have not had any image retention let alone burn in. The set has over 1800 hours on it.
That's a very good tip! Thanks! Could you list your settings?

I was wondering if you have been waiting for the firmware to get figured out before posting these? I would have imagined you would have been subject to countless posts regarding a specific firmware’s affect on black crush and the calibration results.

I thought by the end of this week May 31st new firmware would be ready to download. I was overly optimistic!

You will indeed be happy with the C8, I also own a 75Q8fn, and my C8 is still my main viewing TV for many reasons I wont name on here.

^owners thread...forum etiquette, plus there are plenty of those vs threads...I was merely responding since that member owned the same set I do.
