Strange things happening with picture modes. Viewing SD on YTTV, Amazon video, Netflix in various picture modes. (First 2 weeks, so still figuring out what I like.)

Sometimes when I switch to APS picture mode, it looks better than 1080. Has a 3D effect, almost 4k to my eye. What's going on here, and if it's the feed why wouldn't it look this way in all modes? I have trumotion set to clear in all modes, so that's not it? Anyone have an idea what's happening here?

Do you own the North American model with the small stand? If so, does the tv tilt back.....I am wondering if every N/A 77c9 tilts back as mine does. Does anyone here with a N/A 77c9 have one that stands vertically on it's stand? I will shim mine or wall mount it, but this tilt pisses me off!

My model is LG OLED77C9PUB 77" C9, which I believe is the N America since it was purchased from an AD dealer here.


I will be wall mounting mine and have not set it up on the stand. I had read on another thread that the tilting is by design to prevent the tv from tipping over.

Thanks. This stand is much longer on the front of the tv and having the tv vertical would not cause it to be more likely to tip forward.

Got mine setup on Saturday - I've been astonished at the quality. The old issues from my c6 have completely gone. Noisy, compressed videos look dramatically better - much more like on my JVC x9000 but with real black. Low light performance in SDR is jaw dropping. Netflix Dolby Vision doesn't look gnarly and odd.

I am disappointed at the issues with AutoCAL and the black levels, but I ran a 3D LUT for MadVR using DisplayCAL and out the box my accuracy is already good enough. With my C6 a 3D lut dramatically improved the grey scale and low light performance but none is needed here. In fact - after running a 3D LUT although the red color error improved - a gamma that perfectly tracks 2.4 just didn't look good as the factory default. There's no black crush with the factory default for me on a contrast test pattern but the way it comes out of black makes the contrast look much more inky in a pitch black room.

VERY happy with my purchase. A shame they let the 3D go, but I'll keep my C6 and JVC for that.

Hello - was thinking about the Sony 950G but on the owner's thread for that TV it seems like that model has all kinds of reliability issues or features that don't work or it resets all the time or can't recognize certain HDMI inputs. All this is scaring me off the 950G.

This will be my first TV purchase since 2008, yes I am still watching a 50" Kuro! I was copying D-Nice's settings way back when. The Pioneer Plasma's used to rule this site!

Been holding off for several years till OLED prices have come down - but now want the 77", and even at $5K, it may not be low enough, especially if the new TV will cause me to have agita!

Are you guys generally happy with the operability of the set - I know the picture quality is gorgeous - but how about living with the unit?

Hehe, good times - I also had the 50'' Kuro and was using settings by D-Nice.

I now have the 77'' C9, my notes:
- no noise from fans, I sit 2-3 meters away from the tv and it's silent

- picture quality is amazing

- the bezel is small enough to make this tv look smaller than it is - in my eyes it looks smaller than my previous tv, a 65'' Panny!

- on-board apps: (1) Netflix and Primevideo work perfectly (2) YouTube also works perfectly, and even better compared to my new Nvidia Shield and my HTPC. There's no banding using the TV's app, whereas there is banding on some videos when using shield or htpc. (3) media player - the TV's media player app comes from the 20th century.. the user interface is ugly (just a file manager), and it doesn't play all subtitle formats. The weakness of this app is the reason I bought a Shield. If you don't watch local content, you may not care for this.

Overall, two thumbs up from me.

I was going to buy an A9G but can’t justify the price against the C9. And it’s kind of a strange back, with the bulge low down.

I chose this mount because it allows for easy horizontal adjustment, and got $30 off with an Amazon flash deal.

Change resolution with MacBookPro in clamshell mode

Hi all. Looking for some hive mind help here! When I connect my MBP to the C9 via HDMI nd select "mirror screen" everything looks very nice. The option "LG Tv Optimized" in the configuration settings in the MBP is selected and if I for example play a 4k video from youtube in the MBP it is mirrored beatifully in the C9. Now, the problem comes when I close the lid of the MBP to use it in clamshell mode; then the resolution in the C9 changes totally and actually only part of the video is displayed. I am not sure why this happens. Any thoughts? Thanks!!

Even if you used "the magic of parallelism" to render the same image three times you'll still end up with additional latency as your input will be two frames behind what is displayed on the screen (not including skipped frames which despite being the problem that triple buffering was created to solve can still occur).


There is literally no scenario where rendering frames in advance of input won't result in additional latency.

Set up my new 77C9 over the weekend. What a fabulous TV! Spent a big chunk of money but no regrets. I will have to now re-watch all my 200+ 4k discs to re-appreciate the blacks and image quality. Coming from Samsung (that still has 3D) I've been craving for the true blacks and infinite contrast. I was concerned after reading the screen uniformity thread but so fortunate that I couldn't see any issues with the panel so far. I spent the whole weekend watching 4k HDR content including BBC docs, they never looked better. Overall, very happy with the purchase, should be good for the next few years. Happy to join the club.

New 65" C9 owner here. Love this TV! Switched over from a 10-year-old Sammy LED. Needless to say that was quite an upgrade!

Anyway, is anybody using the LG UBK90 / UBKM9 Blu-Ray player with a C9? I keep reading in various threads around the internets that there is an issue with signal loss when pairing the LG B-R players with their OLEDs. From what I can gather, it might just be people using bad HDMI cables. I just wanted to confirm. Just need a sub $200 player and the LG looks good.

Thanks!

I have just found out something really weird, i am using a 2019 Nvidia Shield Pro and while using that hidden menu (clicking 111111) the HDMI info shows 60hz when watching Netflix. The weird part is that even thou the signal is 60fps RealCinema still has an impact when i enable it, i thought it was only supposed to kick in when 24p content is detected.

I also tried changing my Shield's refresh rate to 24hz and that caused the signal to always be 24fps, i starting playing with this to see if RealCinema would behave differently but i could not see any difference.

Anybody understand any of this? Why is RealCinema doing anything with the content at 60fps? Also, what does the Shield do to convert that 24fps content to 60fps?

This comes up a lot and our understanding shifts as the discussion ebs and flows, however here are my own notes. btw you need to be very clear whether the TV is receiving an interlaced signal or not. Especially in discussions about RealCinema, it's not enough to just use the term "fps"

cribbed notes:
  • On+Source is 24p => Output each frame exactly 5 times (120Hz panel, 24*5=120).
  • On+Source is sending content shot in 24fps, but sent packaged up into a 60i (interlaced) signal (e.g. a movie via cable box) => 3:2 pulldown is applied to fit 24 into 60, which creates judder. Real Cinema applies reverse 3:2 pulldown to get back to the original 24fps and eliminate the judder.
  • Off => Do not apply reverse 3:2 pulldown, keep the judder.

As you can clearly see, it needs to do different things for the two different signals.

Quote:
Also, what does the Shield do to convert that 24fps content to 60fps?
See above, it's doing what a broadcaster does every time it broadcasts a movie in a 60Hz interlaced signal.

Using INTERLACING, you can do what broadcasters do - google "3:2 pulldown". Without interlacing, you'll have to repeat frames and cause stutter, because 24 doesn't go into 60.

Well, I finally received my 77C9 after a 3 week wait and I am absolutely floored by this TV ! I have been super paranoid and worried with all the talk of screen uniformity and banding because I really don't want to deal with returning such a massive TV (and I had to do 2 returns for similar issues for my previous plasma) but the moment I turned it on, all my concerns went out the window and I really didn't care if it had some minor issues. I did look at a full white screen since I had my HTPC hooked up and Windows Explorer as a full window, but it looked fantastic. There could have been minor tints but I didn't bother to delve on it because it was already wayyyy better than the screen/tint uniformity I have with my Samsung plasma (which I have enjoyed greatly). Haven't had a chance to checkout the near black performance since my TV is in a fairly bright room during the day. I wasn't quite prepared for how bright the OLED feels.



For the moment, I did have one question for fellow owners. I have tried setting up ARC from the TV to my Yamaha RX-V375 receiver. This seems to work most of the time, but I've had 2 issues so far:


1. Sometimes, the ARC signal doesn't quite "take" on the receiver side and I have to switch inputs on the receiver and set it back to ARC channel (AV4 for me) at which point it finally recognizes the ARC signal and starts playing back the audio. Any thoughts on why this may be happening and how I might fix this to be a more seamless experience?


2. On the internal Netflix app, I started playing "The Irishman" in 4K DolbyVision, and my receiver would not play any audio via ARC at all. I have ARC set to "passthrough" in the TV settings. Could it be outputting in a format that my RX-V375 doesn't support? Setting ARC to "PCM" worked but only gives me 2.1 output (a documented shortcoming IIRC from reading through this thread). If I use optical, then I get 5.1 audio via my receiver, likely because optical only supports lower bitrate and formats that the RX-V375 definitely handles. I'd love to be able to use ARC and get the higher quality lossy audio when I can, any suggestions on what I could do to troubleshoot this?

Your wikipedia link agrees with me. Here is what they say about triple buffering:

Finally, the displayed image was started without waiting for synchronization and thus with minimum lag.
Here is an article that may help, as it has diagrams:

In other words, with triple buffering we get the same high actual performance and similar decreased input lag of a vsync disabled setup while achieving the visual quality and smoothness of leaving vsync enabled.

Has anyone been able to get Airplay to work with casting pictures to the tv? We have been able to get movies to work, although it's hit and miss when it will work, but not for pictures yet.

I just tried on mine. iPhone 11 Pro Max. Works fine. When viewing a photo I use the share function and AirPlay shows up as an option, with the TV listed.

You might possibly need some other function enabled on the TV like ARC or CEC.

I keep reading in various threads around the internets that there is an issue with signal loss when pairing the LG B-R players with their OLEDs. From what I can gather, it might just be people using bad HDMI cables. I just wanted to confirm. Just need a sub $200 player and the LG looks good.

Thanks!
I have this player and have not experienced any signal loss using monoprice certified cables to LG C9 65 inch.

Here is an article that may help, as it has diagrams:

Weird how they use "decreased lag" and "minimum lag" but not "no lag", surely this isn't a university level topic? Even a single buffer will increase latency. I don't know how to break it down further than my previous statement: There is literally no scenario where rendering frames in advance of input won't result in additional latency.

Seems like your seating distance is too far for 77”?

I have similar seating distance for the movie room and went with JVC 4K with 130” screen.

Would you mind shifting this OT discussion to PM? Thanks!
