I got a pretty sweet deal on C8.

It's my first TV that isn't a 4:3 hand-me-down. Needless to say, I'm thrilled.

The picture is insane. I did a banding/gray screen test and it seems I got a good panel.

I've done my homework but I can't for the life of me figure out:
  1. If I can use my Sennheiser headphones with this TV. I plugged them in both 3.5mm ports and no dice. Not sure why it doesn't work.
  2. If I should upgrade the firmware from the base version.

Anyone have any input?

Thanks!

Plenty of wives do not understand that picture quality does count for a lot. My wife does understand fortunately . But I hear comments from others, like as long it has a picture and is color I am good. That is a low standard, ha! So glad you are enjoying your new OLED. They can look really incredible! Rock on zeonstar.

Well F^&@ me... I got the update notification for 5.03 a couple of hours ago, got excited and applied it. Immediately after the update I see a row of dead pixels across the width of the screen, (65") model. Fortunately LG stepped up and is sending a technician out to look at the screen, with the caveat that they cover manufacturing defects only, otherwise I'll be responsible for the cost of the service call. I'm okay with that as there's no damage to the tv and the kids are grown and out of the house so I know there were no shenanigans involved. However the fact that a firmware update may have caused this irritates the heck out of me, though it may be coincidence but I don't think so.

Okay, all of the above whining being over with... Has anyone else seen this or is there a potential fix for this? Unfortunately I'm aware the 5 series firmware can no longer be downgraded so that attempt is out of the question...

^Obvious question but did you try resetting the TV and re-plugging the HDMI cable to the source device? No idea how a firmware update would cause that.

Nice of ya, so thank you. This is all so new to me. I have always loved Home Theater but getting into 4K and Atmos refreshed my interest in a huge way. If I am 100% honest, I don’t know how much difference I can tell in my calibrated display....but I don’t regret doing it.

Sorry, update was 5.10.03, can't edit. Yes first thing I did was switch inputs, I have a media center and cable box. Both have the stripe. Reset the TV unplugged for 10 minutes still had stripe. Called LG they had me put a video app on the phone and show them the stripe then had to do the picture test under picture settings. At that point got the we're sending a technician out. I kind of agree but the timing is just too tight not to bring it into question, restarted TV and within 5 minutes I saw the stripe.

Bummer man. That's an odd one.

Probably won't do anything but maybe try running the "clear panel noise" cycle.

I have a single stuck green pixel after 5.10.03, I noticed it the day after I updated. I don't know if it's coincidence or not. I've been too busy and now I'm traveling so I haven't had time to see if LG has any suggestions, I did run the full pixel refresher three times and a few 4 hour comp cycles have run since then... Still there, or it was before I left home. It's not the end of the world, but I suppose I should see if LG would do anything about it... I haven't ever had a stuck pixel on any TV before, so, it's pretty jarring to me considering the C8 is the most expensive/high end TV I've owned.

As I mentioned above, I just updated from .15 to .03 and did not see any real difference in pq (my C8 didn't have any of the issues previously reported). I definitely don't see what you are experiencing.

I never trust an atom, they make up everything.

Last month you posted that you were going to get a calibration by Robert Busch. Has that happened? Are you satisfied with the outcome? Was it money well spent? I'm also in his territory and have been thinking about a calibration.

Yeah it did, in late July. He was able to get me in pretty quick and it was a really great day. I think we spent like 5 hours on my TV alone. I am very happy with the results. I really enjoyed the whole experience.

It wasn't originally planned but I had him look over my sound system too and ended up getting a basic consultation on it as well. We didn't change much but what we did change actually made a big difference.

Usually they will not hurt calibration, however in rare cases I think they have.........Lets say it never has, there is always a first time as well.

I think alot of things changed with this update, but it could of been mostly the things that I wanted.
Its always a gamble........odds are a person would be fine

Hey all, so I have had my tv for more than a year, had it calibrated by Magnolia Best Buy.

So I'm seeing some issues that I just don't know if it is normal or I have a messed up tv.

In Dolby Vision shows or any HDR shows like Chilling adventures of Sabrina, Punisher, Series of Unfortunate Events or even from Apple TV movies (Dolby Vision), there is a HUGE lag on going from dark to bright. So if the scene is very dark, it just stays dark unless an bright light forces the rest of the panel to get brighter. I can even do this manually.. if I'm watching a video and scene is really dark and then I press the volume button, the whole image gets brighter (not talking about the white volume text).

And I'm watching this in a dark room. Anyone else seeing this HDR issues? Is it magnolias calibration fault? Any help or insight would be appreciated. Overall, a superb tv but this lag on switching dark to bright scenes is really making me want to switch to another manufacturer.

C8 77"

That sounds like ABL. It's something you can turn off in the service menu. I turn it off on my calibrated tv in my living room because I have a 5 year service plan that covers burn in and everything else so I can take the risk but I leave it on in my master bedroom because I don't have a service olan. I don't know if there are any downsides to disabling it but it may not be the best thing for you to do.

I only did a 20 point grayscale sweep for these comparisons and I think overall LG brought the gamma back to where it was before but due to the stronger near-black dithering which mostly affects the below 5% range I think depending on panel variance there might very well be some changes there.

I didn't measure the near-black range for these comparisons because I wanted to do it at default settings and my panel is insanely too dark below 5% when using default settings so I can't even measure that with my meter. This panel has always been like that even with older firmwares and getting the below 5% range right has always given me trouble.
In hindsight it would've probably been better had I done these comparisons using my calibrated settings including near-black measurements but it's too late for that now thanks to LGs downgrade block.
There are not to many (only you and myself) doing such measurements starting from a "known" base (i.e. Default).
What I have noted for sure is that this lost of luminance from 05 to 50 IRE affecting post 04.10.20 has been fixed.
What to me results not having been 100% recovered, is at and below 05 IRE (your meter/panel critical area - I remember you tell me you have an I1D3, so I would "blame" pannel variance). This, from what I measured, is very evident for Technicolor (106 Nits), rather than the other expert modes (>180 Nits). This somehow matches my understanding of the way near black flashing has been fixed, i.e, not using the W led at very low luminance.



My further measurements (I try to get enough detail at low IRE by using also my eyes, matching near black patterns), tell me that a basic luminance pre-calibration does a good gamma job, with the exception of Technicolor, where a bust in luminance is need at low IRE.

I gues you meant ABSL. ABSL dims after a while to avoid over panel heating, and can be disabled in SM.
ABL cannot be disabled. It allows part of display to sustain more luminance than the one allowed for the whole display. Basically it works allowing an average luminance and allowing isolated peaks.

That sounds right. There is something (ASBL) in the service menu that can be disabled that prevents it. It's disable on my set.

The LG OLED TV will dim when the "average" picture stays unchanged for more than 60s.
This can be really annoying when watching videos/movies that have scenes longer than 60s.
This feature/function cannot be turned off in the normal user accessible menu. It can however be disabled the Service Menu (also known as IN-START):

How to access the Service Menu:
Follow instructions given here or buy the Service Menu Explorer LG TV Android App (US$ 6,06) (See attachment 01).
Press the blue button on the left, labelled "IN START" in my screenshot.
The TV will ask for a password, it should be 0413.

What to change:
Go to "13. OLED" (if you dont see it, press exit on the remote and access the Service Menu again).
Set "TPC Enable" to '0' or 'Off' (depending on your model/firmware). (See attachment 02)
Press Exit on the remote. (The change will be saved)
Enjoy.

Tips:
You only need the App to access the Service Menu, you can use the normal remote to enter the password and navigate inside the menu.
Return doesn't work, you will have to use the app button (the left one, blue, labelled "IN START" in my screenshot) to "navigate back".
The Red button on the app gives you access to "EZ Adjust".

Disclaimer: I don't know what "TPC" stand for nor if this is:
- A power saving feature
- A feature to prevent burn-in
- Both of the above
So turn it off at your own risk

Guys I have a question. Everytime I start the TV I get the update notice. Is there a way to disable it? I don't want to update

Thanks guys!
Can you comment the possible black crush in DV mode using 5.10.03 that was reported multiple times by different users? (I can't since I'm still on 4.10.25 B8)
Thanks

Well, my fear came true, I accidentally updated my set from .15 and cannot revert as I always did in the past.

So if you're watching bright content, the gamma and overall picture is not dramatically different than .15, which is good.

The problem is dark scenes. When there are dark clothes in a dark scene or similar, I see detail missing, some areas have become blobs of black.

.15 was just ideal for me. I did have a bit of the white flashes in select dark scenes with .15 but I saw that as a technology limitation rather a flaw. I was happy to live with that.

You will forget it after few weeks specially if you won't notice it easily unless you really search for it. If your panel is good and it's hardly noticeable then just leave it.

It’s not terrible. I don’t see it 99% of the time. Hoping it goes away. No need to swap out panels since otherwise it’s absolutely brilliant.

I got one on May, I tried the pixel refresher and even some youtube videos but still there until now. I won't notice it unless I will really look for it and most of the time I can't find it immediately. After 2 weeks I forgot it's there. May panel is great also, it's not worth the risk to exchange it I might got a worse one.

As you said, "that you noticed after the update". There is practically no way for the firmware update to create stuck and or dead pixels.

Yeah, I am sure it is a pure coincidence. It seems very unlikely that it would have been the FW upgrade.

Interesting. I don't see any difference between .15 and .03 on my 65 C8. No loss of detail, minor flashing, or what ever.

I never trust an atom, they make up everything.
