Nothing to do with RGB levels. RGB and YCbCr444 are two different ways of sending the colour information. You can see in my screenshot my laptop is sending YCbCr444 and I have never renamed any of my inputs to turn on PC mode.

Setting the C9 picture mode to game might turn off some of the picture processing that is making your picture look bad in non-PC mode.

Yeah just did the opening scene driving around in the dark then walked around for a bit in outlast, nothing but smooth gradients. If there are any other games where it's noticeable that I might have I can give it a try, but I'm not seeing it. Maybe hardware variances or some other variable?

Can you take a pic of your HDMI Diagnostics screen so we can compare with his?

I can confirmed that setting YCbCr 4:4:4 and forcing the TV to use HDMI level "Limited" fixes the issue. Losing 0-255 is much less noticeable than losing 4:4:4... so thanks for that.

I guess I'll run the set in 16-235.

You cannot get 4:4:4 in non-PC mode on LG OLED, it's been that way for years. I manually set game preset to the same settings as ISF dark mode. Everything looks the same but 4:4:4 text tests.

Thanks for trying, I played all of outlast this week and only noticed it in one or two areas. Bioshock is the biggest offenders I found so far, it's so bad that it makes the set appear faulty. It seems limiting the display to 16-235 (YCbCr444) mostly fixes it for me.

Hi there!

Brand new C9 owner here, what a TV! I'm delighted!

I've did a lot of reading recently regarding the TV/settings/quirks etc but there's one question I can't seem to find a definitive answer too, so if someone could help me out and supply me with answers I'd really appreciate it. I've browsed over this thread but it's such a behemoth it's difficult to find.

Anyway, I understand when playing a HDR game (say for examples Gears 5 on Xbox One X) you can choose the specific 'game HDR' mode in picture settings, my question is simple, what benefits does this have over other HDR settings? Such as Cinema/Cinema Dark etc. I presumed low latency mode would be activated under any picture setting automatically?

One of the features of this TV that appealed to me was the fact you can play using low latency while having any picture settings active you like, such as dynamic tone mapping etc. Most other tvs don't really allow this as you know.

Anyway if someone could advise/educate me that'd be great.

Thanks in advance!

I just bought the LG C9, where can I find good settings For cable, 4K video, etc to try. Is there a post here by any chance that a lot of people are using.

Sorry it turned out a little blurry. The differences I can spot are that mine is showing 59.92hz vs 60hz and scaninfo has Horizvalid vs Invalid.
Oddly mine also has a rapidly fluctuation error count for CTLE Ch1 Result,

It did display Atmos when switching to internal speakers but went back to 5.1 DD+ after switching back to eARC.

I haven't heard anyone here (other than you) discuss the actual use of WiSA with these displays. We have had some conversations about WiSA, in general terms, as it might work. But, AFAIK no one has ever said they were using WiSA.

You appear to be our pioneer. I think we'd all like to know if lossless audio is possible via WiSA.

I'm not sure we even know that WiSA will work, at all.

If you switched back to eARC while it’s playing then it doesn’t sound like the bug the rest of us had.

What AVR do you have?

As I wrote before, have the same issue. Sometimes its works but for mostly not.
I have Yamaha 2080.
Got Atmos while playing from external source such as hard drive connecting to USB on the tv every time!
I reckon this is Netflix issue or combination LG/Netflix.

oh your eyes are not playing tricks, you have bends and waves probably in all panels.

Yeah, you're right. Tried both RGB and 4:4:4 and the TV does some kind of weird internal 4:2:2 processing on the image even though the input signal is not sub sampled.

It's odd that it's fixed on the latest firmware for some of us and not for others.

So pc mode on c9 is still a no-go due to banding issue? The reason I want to use pc mode is because then I can enjoy low input lag with other picture preset e.g. technicolor instead of game which is very inaccurate in colors according to flatpanels’s review

HI,

I'm a new owner of the C9 for a few days now.

I Cant get CEC or Simplilink to work. Everything is switched on in the Simplilink Menü, but it doesnt work.

I Worked fine with my C7 before.

I Think it has something to do with the device connector. Controlling my apple tv via cec works until the message appers "you can use now your magig remote to Control the device" I think its somehow switching from cec Control to ir universal Control...

What should i do?

Thx

To many variables such AVR type, cables etc. but prefer when things working or not permanently.
C9 in my opinion is a great tv but software need to be improved for connecting any external avr , sound-bar, meets eArc standard but is not.
Switching all the time between Atmos and 5.1 to get finally Atmos thru HDMI cable is not the solution, at least for me.

Hi all. I got a b8 55 about 2 months ago. I've used it for 240 hours, I absolutely love oled. However I greatly prefer how pc games look on this thing. Particularly with HDR. I also have a Acer xb270hu which is a 144 hz gaming workhorse. The difference between them is astounding. I always prefer to play on the oled because games look unrecognizably better and become immersive as a result, however I'm finding that even on my 1080ti that I often end up playing on the gsync screen be because 1440p at variable refresh is far more smooth. I find adaptive sync to be the best tech I've ever used or on par with oled pixels.


So it seems I'm basically someone that's going to benefit most from what the c9 offers. Unfortunately selling a TV and a graphics card is a pain. As I'm going to have to downgrade to a 2070 which is the same cost as what I would make back from the 1080ti.


Considering my fun is had testing and playing games as immersive showcases. Do you think it's worth switching. I virtually never use it for films or TV. But I keep it protected by dark mode + no icons or taskbars and just being mindful of burning.


I enjoy my b8. But the stutter from no adaptive sync is something I notice on all games that are not retro at native res. The 40-58 range plus input lag improvements could be the best of both worlds .

The other major issue with my b8 is that it's too dim. Just slightly.

@Laupe

Change resolution to 1440p, keep pc mode enabled, put Nvidia (or amd) to limited (16-235) not full (0-255) and manually put on LG black to low, not auto. Does that fix it?

It happens on 1440p120 too. I think PC users should avoid RGB and force YCbCr444.

I tried the following setups in PC mode:
RGB Full with TV set to HDMI Black Full = Banding/Posturization
RGB Limited with TV set to HDMI Black Low = Banding/Posturization
YCbCr444 with TV set to HDMI Black Low = No Banding/Posturization and 4:4:4 is kept

This matches what others have reported with HDR games and PC Mode. HDR just makes it more noticeable but it's definitely happening in even 8bit SDR content. It takes certain, usually very dark, scenes to bring the issues out. I played ~8 games (52 hours over 2 weeks) on this set before realizing something wasn't right. I noticed it in a few games, but naturally blamed the games until I decided to do some tests. It's really bad in some dark horror games but basically unnoticeable in most games, and that's why I think many won't ever notice it.

My tests are the submarine ride at the very start of Bioshock 1 Remastered and some of the later dark levels in Amnesia: A Machine for Pigs (which is the worst offender i've found). Its a night/day difference when it's working as intended in these. It ruined my Amnesia experience, as I thought the horrible posturization effect was just poor design choice, I was googling trying to find ways to get rid of it but no one had the same issue. Game looks great in YCbCr444....

Hello everyone,

I have a question about LG C9. I have had this since July and experience problems with flickering of the image. It appears to be especially true with devices that are connected via HDMI. For example, when I watch a movie through my Himedia PRo Q5 media center, the image flickers in some colors. If I play the same movie with the C9 media player, I don't have this problem. I also have the same problems with the Xbox and TV provider box. But when I watch TV through the CI module, I don't have the problem again. Recently, the motherboard, panel and power supply have been replaced by LG. This has not solved the problem and they now say that it is a feature of the TV and can do nothing.

All image enhancers are off, including Oled Motion.

Does anyone experience the same problems? And how did he / she possibly solve it?

I have the Denon X8500H but I don't believe the C9 knows which AVR I have. Maybe that's why I may need to do a factory reset?

Do you want do factory reset in your Denon? Let us know how is going afterwards

With the beta nvidia driver it kicks it into auto low latency mode which lets you select any picture preset with out being in PC mode

I noticed the same when watching movies and wondering about all the banding.

I use my C9 as a HTPC and second monitor and I've been simply using Game Mode, when I need to play games, and isf Expert (Dark Room) when watching stuff. In the Home Dashboard I've set the icon to "Home Theater".

I would rather do the factory reset of the LG first than on the Denon.

Ok let us known afterwards.

I messed around with HGIG for a little while on my PS4, and it just seems to set Dynamic Tone Mapping to off and that's about it. We probably won't know much about how it works until we get a confirmed list of games that work with it. Comparing the two, I prefer the settings I've had on my TV (which do include DTM set to on). It looks dimmer and I seem to lose some detail in dark areas when I set it to HGIG instead. I tested the feature mainly with Spider-Man and inFamous Second Son.

Oddly enough, I think I prefer HGIG on my Xbox One X, but I only tested it with one game on there so far, Shadow of the Tomb Raider.

440.97 Game Ready Drivers are out.
Anyone tried running the tv at 1800p @ 120hz ?
