Frankly it's ridiculous and I can't imagine this is what an OLED set is supposed to look like.
I have made sure HDMI black level settings are correct, re-labelled output for 'PC' 0 - 255, and using 'High' black level setting.
Also tried limited and low and any other combo - just cant lift the darkness.

Has anyone else had this issue or is my panel faulty. I noticed the video on Youtube is a recent upload and my set is manufactured in July/2018 - perhaps bad batch.
I'm really annoyed that no content is watchable due to this, especially with the premium price paid, and I'm seriously considering a obtaining a refund.

Any AVS expertise is appreciated
I've read that there's alot of changes within the first 200 hours of the tv so if you haven't got that yet Id wait till then and then try to dial in brightness. I've also read resetting the tv can fix the crush too so you might wanna try that

Here is a video of what I’m seeing with my c8. I seem to get a lot of micro blocking in dark scenes just out of black. It seems like when somthing comes into the screen just out of black the pixels fire on brighter for a second. If I pause it the micro blocking is not as near as bright and noticeable. I’ll add a link to a video of it doing it in the revinant.

Quick question: I just read that the LG has a feature that dims only the static logos on the screen while the rest of the screen is at regular brightness. How well does this work with HUDs in gaming? If it works well, this would make the LG C8 an instant buy for me.

Does it show up as being listed as Atmos, or do you just see that it's an Atmos track on your receiver?

If the former, maybe I need to reset the app somehow.

I been running it since day one with no issues. I'm in the USA and there may be issues flashing it on European sets. I have not noriced any lip sync issues since installing it but only noticed a couple different movies before. I'v only had TV 2 weeks today...a 77C8


The change-log I seen mainly was addressing lip sync issues...although there were a few other lines

What's the usual lag time between Korean and North American firmware releases? Or does North America (or other regions) sometimes skip firmware releases?

I really have no idea. I have flashed sammy firmware before from china and it still wasn't in US 5-6 months later(JU7100). Actually this is my first ever LG TV...if it's anything like their phones the SW updates are very slow coming

Anyone else?
I just saw this last night while watching the Mayans and thought it was the content, but I checked it with blue ray and streaming apps and yes I had the light bleed in the corners. I paused a scene in Deadpool 2 and I could see the light doing like a bloom effect. I tried a couple of things and turning the brightness back down to 50 in all modes fixed this and it went away/barely noticeable. It just happened last night for the first time and I am wondering if that is because I am getting closer to the 100 hour mark and my panel is settling in. At 88 hours at the moment. I had the brightness from 51-53 depending on the mode, but like I said they are all back down to 50 and I see no noticeable difference other then that light bleed/bloom is gone.

So I just read this new part of the thread and was like huh? In Netflix it shows that there is an Atmos soundtrack. I had just watched Jack Ryan but this was before I set up my ARC, so it was on optical cable. I just went into the Amazon app and started watching Jack Ryan. It shows when you select the episode it is Dolby Vision and 5.1, but when I went to the Marantz app on my tablet, low and behold, it is playing an Atmos track (and it showed on the front of my receiver as well). I am in the US and have the firmware update from weeks ago, my TV is not showing a new update yet here. So, if you have a way to check your receivers output, you can verify that way.

I don't have the C8 anymore, but from what I can remember, it did nothing at all in game mode. I think maybe the decontouring filter was the same in that way. Logo dimming worked really well in the other picture modes, noticeably dimming bright HUD elements such as the health bars in Tekken 7. But then you're stuck with ~50ms latency versus 21ms, which is quite noticeable. Unfortunately, it seems that games where the low latency of game mode is almost a necessity are ones that are also likely to feature a mandatory, often brightly-colored HUD.


Hopefully someone else can confirm this for you. If not, I have an e8 coming tomorrow, so I should be able to test this out in a few days.

It says Atmos on my receiver. The app just says 5.1 IIRC. Amazon seems notorious for mislabeling and/or hiding their best content.

Looks like the same issue I had. Use a brightness pattern and if you get the same I got in the attached picture, you have a bad panel, needs replacement. My replacement panel was fine, this TV just looks amazing.

That looks crazy. Is it just any brightness pattern that can show this..and do you have to bring brightness up high to see this (im assumimg thats the brightness slider in the photo, i couldn't read it). This looks like a defect that'd be immediately noticeable on regular content..did you really need a pattern to see it?

OK. It looks like I’m not really getting Atmos. Netflix says the audio is Atmos but my Marantz receiver seems to be getting the DD+ stream only. Cycling through the various receiver sound modes (by toggling the mode selector button on the front), It was DD+ with Dolby Surround or else with Neural:X. Atmos was not an option.

I started playing with a bunch of different settings through the Marantz iPhone app and finally the Dolby Atmos badge lit up on screen and the receiver started receiving Atmos... for a few minutes until the sound cut out completely. Then after that no matter what I selected for ARC, the sound would come on just for a few seconds and then would go silent. This was across multiple apps. I reboot the receiver and no change. I then unplugged the TV and reboot it and the sound came back over ARC, but again just with the DD+ stream sent even though Netflix says it’s an Atmos track. Amazon Prime Jack Ryan is also DD+ over ARC.

It seems that although the track is indeed Atmos, most of the time it cannot properly negotiate a proper Atmos stream so I get DD+’fallback.

Actually DD+ seems fine and better than optical, but it may make sense to turn off Atmos completely so the LG won’t even try to send it.

Do you have an actual Atmos speaker setup on your Marantz? If not then you will never have Atmos sent to it (you’ll only get DD+ from the LG)

Thanks for reply.
No my panel doesn't look like that. Mine just has no detail in low blacks - a black in a scene is zero level black, blackest of blacks (which you never see in real life) and just eliminates any detail in shadows. It's akin to having gamma normal for the bright content in your picture and gamma 3 -4 for the lower dark content. Just horrible for watching film/movies.

Anyhow, decided to return the Tv, not just because of that problem - panel also displays blue and pink tinges to white content, jhas vertical banding evident on grey screens, flickers on grey screens, has a very small amount of 'grey glow' on blacks in the bottom corner (mentioned by another user above - looks similar to ips glow) and the motion on these oleds is terrible.

I have been wanting to change over to Oled for so long, and as a long time fan of Plasmas believed that the time was right. As much as i want to invest in Oled IMO it's still an under-cooked technology.
I will say that the panel was perfect in gaming. Best motion I've seen in-game on any display. However LG needs to fix up how these TVs handle low frame rate content ie. film - the judder is terrible.

Sigh - back to my Panny Plasma and LCD monitor till next years models perhaps.

I think it has to do with the content. Check out episode 2 of Lost in Space Netflix when the dad goes to the waterlogged room in the lower deck to check the fuel lines. Truly stunning blacks.

But then in later episodes in some scenes in the forest, some of the blacks look crushed.

So, another thing I do with my receiver, if you haven't already done this, is to unplug the Marantz and leave it unplugged for a minute or so. I do this whenever my receiver is acting weird or gets locked.

Watched first episode of 'Jack Ryan' on my C8 last night. Wow...quite impressive. I ran it with the default Dolby Vision settings and did not have to adjust anything.

A question regarding this setting - Dolby Vision Cinema (User):
I notice that the White Balance is set to “20 Points IRE” (with an IRE of 100, and no R/G/B adjustments), as opposed to “2 Points” (which is what Dolby Vision Cinema Home is set to). I have all of my other picture modes (Technicolor Expert, ISF Bright and ISF Dark) set to “2 Points”, with R/G/B adjustments, per my earlier settings.

So which is better/preferable/more accurate - 20 Points IRE or 2 Points? And what is the difference between the two?

At a very quick glance at the beginning of Jack Ryan, the skin tones seem slightly skewed towards red, vs. my other settings.

Thanks for any input!

Received my new 65” LG C8 yesterday but Purolator jammed something into the box during shipping and the display panel is bent in. It looks fine when on, but just going to be a b*%ch to get this unit switched now. The screen itself was saved by the styrofoam, but still bent.

Got a 55C8 last week, but I'm exchanging it to hopefully get one that's perfect, the screen uniformity was really awful and also presented sometimes weird artifacts

I didn't go through the whole thread, but is this something common ?

That's true that no screen is perfect, but some screen issues are defects and it's better to cut and run so a return can be made within the return window. After a couple of hundred hours if you have major screen issues, chances are they won't work themselves out.

The television screen is the retina of the mind's eye.

I noticed the problem on the first day while playing a movie in 4K Dolby Vision with the default Home Cinema picture setting, the movie black bars were perfectly black on the right side of the screen but greyish and waving on the left side of the panel, I first think about a source defect, so I changed movie, HDMI cable, player... but still got the issue, am I asking too much from this OLED panel or can I hope for a "not perfect" but better experience once replaced ?

Thanks

Cable Box CEC question

We got the 65" C8 a couple of days ago, and still getting it settled in, but one perplexing issue has arisen.


The new LG replaced a Samsung Plasma (64F8500), into which was plugged a Samsung sound bar, an Oppo Blu Ray player, and a Samsung cable box. This is the cable box in question: https://www.amazon.com/Samsung-GX-SM...70_&dpSrc=srch


With the Samsung TV remote, we could control all three devices using the Samsung TV remote, through the TV via HDMI CEC. One remote ruled them all, and it was nice.


With the LG C8, we have the LG remote controlling the Samsung sound bar and the Oppo Blu Ray player OK via HDMI CEC, but not the Samsung cable box. I go into the menu that enables CEC, tell it that a cable box is on HDMI 1, click on Samsung as the cable box brand, and it offers me three different remote options to try. None of them respond.


Is there a trick to getting this to work, or are we just out of luck with this TV and cable box, and have to juggle two remotes to change the TV channel?

I’ll add a link to a video of it doing it in the revinant.

Your issue was discussed earlier in this thread. Search for @jk32 posts along with my response and test image. Unfortunately, the problem is inherent to all 2017/2018 LG OLED panels so will affect Sony too. Stick to less compressed material where the issue will be harder to see since it will affect smaller pixels areas instead of the large patches of color that are common with higher compression.
