And this is why the HDMI screen says it's 8bit RGB, because it IS 8bit RGB at the transport layer, which is all that screen is looking at.

Where the heck did you get this tunneling theory from?
I should really ask you where the heck did you get your irrational disbelief of new information from? It's not theory it's fact, you can find it in posts on the Calibration threads, the HDFury thread is a good resource; posts from Spectracal, @ConnecTEDDD , all over. Here's one, and no, it's not the only one.

I'm more disappointed that you just flatly stated "that's wrong", misleading readers, without wanting to learn anything, merely because you didn't know about it . Dolby Vision's method of transporting its signal is not news and has been known about since the start of Dolby bloody Vision!

Are you going by eye, and if so are you generally highly sensitive to SOE and other weird motion processing issues and artifacts (aside from OLED stutter)? or are you using some kind of gadget to measure perceived frame rate?

Now I'm wondering if I have a bad unit, or something configured incorrectly. Or if I am seeing "correct" 24p playback on OLED for the first time and it just looks weird to me. I'm definitely seeing it on webOS-driven streaming sources as well. I'll check the hidden menu to verify I'm actually looking at 1080p24, 4Kp24, etc.

You are right. I was wrong.

Thank you for beating me over the head with a clue bat. I deserved it.

I shouldn't have issues with both the tcon board and power supply out of the box which would be a shame since my uniformity is pretty good.

Interesting. I have been playing RDR2 since release on C9 with gsync and never saw it flicker.

Anyone used murideo 4K test patterns on YouTube to check their black and white levels on their c9?
If so can I get an accurate outcome if it is less than 4K streaming?
With our internet I will be lucky to get 480p.
It’s almost always below 1 Mb/s.

Dolby Vision's 10 or 12 bit 4:2:2 signal is tunnelled inside this 8-bit RGB container, which is why Dolby Vision works over HDMI 1.4 connections.

Finally when you say "the tv can properly interpret the bits for display purposes" you may be forgeting that it's the Dolby Vision processing engine which does this, not the TV. Dolby Vision is a "black box" and the TV manufacturer has no access to this even though it's running inside their own TV; it's fully controlled by Dolby. Often used to be called the "Dolby chip" inside the TV, it's easier to understand it this way even if it's not the way it's implemented in current models.

HTH
I am sure that you have your facts right. I would humbly suggest that a different choice of words in your initial post would have avoided some confusion.

When I use Wireshark to sniff IP packets it _could_ claim that «its all bytes, dummy». It does not, however. It interprets those bytes and may say that a given packet is protocol so-so, and encodes for e.g. a 16-bit word.

As my tv shows a popup claiming «Dolby Vision», clearly, some part of the tv knows that this is a DV stream. Now, it might be that this gui overlay is rendered inside a blackbox Dolby chip but I doubt it. At the very least, the tv have different image settings for HDR vs SDR, I dont see how the LG engineers would practically do that without knowing what kind of stream they are working on.

I think (?) what you are saying is that this menu is a HDMI debugging sniffer that only attempts at low level protol/stream setup info. At that level you probably are right that «8-bit» vs «10-bit» look the same. If so, I question why LG would want to show a value if it can never be anything else than what it is right now («8-bit») but I digress

I currently have an HDMI connected straight from the graphics card to the C9 so I can get G-Sync, then I have another HDMI connected from the Graphics card to a Newer Denon AVR. When I watched Netflix 5.1 Content on my PC, it only outputs Multi Channel "Stereo." When I select Dolby Surround Sound on my Receiver, it outputs the voices into the 2 tower speakers and NOT the center channel. Please let me know if anyone has this TV and uses their PC connected to it and a receiver for gaming on their PC and can get Surround sound. Thanks!
many of us do this same thing separate hdmi cables from pc to tv and avr.
this works no problem with my old sony avr HT-SS380 i get 5.1 pcm no problem as well as dolby true hd and dts ma
my only advice really is make sure windows is set up for it in the advanced setup menu and try out the test audio and see if it comes from all speakers and the correct ones
Have you gotten 5.1 Audio out the C9 connected to your PC and AVR? In Windows it shows that my AVR connected supports DTS, DTS MA, etc but I'm still only getting 2 channel audio out of my AVR when connected to my PC for gaming. What settings in Windows do I need to adjust? Thanks!

Hi, there no problem with LG Diagnostic Screen identifing DoVi content. The stream is 8bit RGB:

The HDR10 are not using Dolby's HDMI Tunneling (RGB 8-bit wrapper method), they stream according to your player output settings, so it can be YCbCr REC.2020 10/12bit 4:2:0/4:2:2/4:4:4 with HDR10 metadata thru HDMI 2.0a.

Also the content can be responsible for the stuff are seeing, for that reason I recommended from users to use only content which have control of the frame rate (no streaming services), a blu-ray disk of a commercial movie (which is always 23.976p/24p).

There'll be an update "Q2 2020" as I've read it that fixes this. Until then I don't know if it can be fixed. I've connected through my AVR for now.


Also, when connecting the PC directly to the C9, I get significant audio delay. Not sure what causes it, but I didn't want to spend too much time debugging right now since I have to use PC -> AVR -> TV at the moment, and then the audio works fine.

Anyone able to get surround from the C9's internal YouTube app? I only get stereo, even on some surround sound test videos on YouTube. (I get surround from the HBO app, so my setup is seemingly fine.)

Just looking around online, seems the x2600h is decent and does everything I need; can anyone confirm it’s eARC works with the C9?

And does it enable connected devices to pass through functions like VRR for the Xbox one?

yes i get 5.1 while connected to my avr and c9 separate HDMI cable for both my Strix 1070Ti has 2 HDMI ports thats one of the reasons i got it because i knew i would need to do this im not upgrading my avr until HDMI 2.1 ones are out

in windows go to the sound control panel and click configure on your avr and set it up for your speaker config should look like this:

Hi fellow tech fans. I have upgraded last week from my oled c9 55 inch to a 65 inch c9. While the 55 inch was a perfect display in terms of uniformity, the 65 inch is, as you'd expect a different story.

Stunning image overall, but I immediately noticed a vertical band right out of the box. So been reading about this "problem” a lot and watched some videos. The past days I can clearly see it improving. But it is not gone. The famous Marco Polo test was successful. So in that content it won’t be irritatingly visible.

But! I’m a gamer and pan a lot. In most scènes it is not clearly visible. Even BOTW on Switch you need to look for it. But when viewing a bright white area and you pan, it is clearly visible (to me). I just got it last Thursday. So been watching almost a week for approximately 4-5 h average a day. So is have around 30-40h screentime. It will likely get better if I understand the breakin period correctly. Xbox one grey settings menu are uniform.

So my question is seeing my screenshots attached I’d like your opinion on how bad or good it is. And if it’s in the high end of best displays, or in the 'try the lottery' end of display quality.

My personal opinion is that comparing to others screenshots and video's I think I have an orange instead of a lemon. It might become a strawberry over time, or a really sweet orange. My wife can't see it, and I havent told her where the vertical band is clearly visible. What has been seen, cannot be unseen. I'd like to see your reaction on my screenshots! I have taken these on Monday in the complete dark (worst case and camera obviously registers more than I see with my eyes). The screen has had a new auto pixel refresh since then. It looks even a little better now. Havent done a manual one, because I trust the tv doing his own circle. I love OLED btw. It's out of this world.

You really need to look for it even on those pictures... I can't imagine this being an issue in real life content watching but I guess some of us are more sensitive than others to picture uniformity.

I think it looks pretty good, i cant see any hard vertical banding. Although you could take more realistic pictures. For example use the "isf dark room" out of the box picture mode and adjust your camera ISO, try to match it like how you see the screen with your own eyes in terms of brightness.

I took some shots from my C9 after 20-30 hours of viewing.

Sometimes i can see some vertical banding in dark scenes, but its very very rare. I havent seen it at bright white scenes to this point, for example while playing RDR2.

Thanks for the quick reply, that gives a good feeling about the screen uniformity. I will try to set it to ISF-dark room and with changed ISO to take some more realistic pictures.

Been playing RDR as well. I do see it slightly in bright skies in that game when looking for it. Also it is really clear in
with the pan over the beach. But as said: I think it is improving since OoTB. That is tip 1: don't start looking for things immediately (I did do that obviously).

I can't seem to find the total viewing hours information in the menu's. It is just not there. Could it be that its language specific? Would be dull if that is the case. I have it set to Dutch.


I do see that with all the compression on YT, as little as can be seen of the vertical bands it is almost completely gone. I think ill keep monitoring, but can be satisfied with what I've got

Ill update my experience further down the road. I think its interesting information for new OLED 65 inch owners to know how much the screen 'breaks-in' after time!

For the vrr & allm features, you will need to run the Xbox direct to the tv since no current AVR has 2.1 HDMI.

You can then run HDMI from HDMI 2 to avr for the audio

Hi,

noticed in my lg 55 c9 that when I go to the Youtube app and change gamma picture doesn't change.
Only when I turn on some video, then gamma change causes picture change.

Do you know why this is happening and what can be done to fix it?

Been playing RDR as well. I do see it slightly in bright skies in that game when looking for it. Also it is really clear in this HDR video with the pan over the beach. But as said: I think it is improving since OoTB. That is tip 1: don't start looking for things immediately (I did do that obviously).



I can't seem to find the total viewing hours information in the menu's. It is just not there. Could it be that its language specific? Would be dull if that is the case. I have it set to Dutch.



Also for reference here is a link to Zelda BOTW clip.



I do see that with all the compression on YT, as little as can be seen of the vertical bands it is almost completely gone. I think ill keep monitoring, but can be satisfied with what I've got



Ill update my experience further down the road. I think its interesting information for new OLED 65 inch owners to know how much the screen 'breaks-in' after time!


Interesting... my current Q9 has a lot of DSE so will be interesting to compare it to the C9 when it arrives tomorrow.

The 2018 October 30th update should have added Earc to to your 6400, I have a 3400 and it works great

I can’t post a link but if you look at the AVS “Official” 2017 Denon S/X series it details the firmware updates in the first thread starter post

Yeah, that’s what I thought - but researching online it seems the C9 doesn’t work with it.

Just ordered a bargain x2600H.

Also - if I connect an Xbox One X to the C9 for VRR, am I right in saying that it can send Dolby digital / DTS to the av receiver with no lag via eARC? It’s just Atmos on the One X that has the lag?

I have my X connected to c9 and HDMI earc to my pioneer avr.

There is no audio lag as long as you select paasthrough audio in the c9 earc audio options

So I can easily check even the 4K YT videos on what kind of audio is being played.

With that, please give me an example of a YT video in 'surround'. I'll download as well as check the audio file available in the video for you.
Works fine for me. Read the release here:

(Remove the DOTs and spaces, for some reason it won't let me post links.)

Interesting....! And that's sending ATMOS to the AVR, and using VRR on the Xbox One X?
