To all of you, switching to eARC. Do you recognize some small audio/video desync with this configuration? Its definitly noteable on the "TV App --> eARC" method compared to the "Shield/ATV --> AVR --> TV" method. 

So no Desync at Shield/ATV --> TV --> eARC (AVR) ??

 

BTW: i have the same issue with DV and this LG Update. Waiting for a hotfix

I don't use any of the TV's internal apps. My sources are Apple TV 4K, TiVo 4K PVR and LG 4K BluRay player. I'm not having sync issues with any of these sources. Not sure what you mean by "Shield".

Same issue. After update to 5.10.04, Apple TV playing Dolby Vision content to the C9 through my Denon 6300X receiver no longer works. Screen flashes black. Had to turn Dolby Vision off to resolve which is of course not ideal for an expensive OLED TV that you bought to use with Dolby Vision.

Hoping LG can push out an option to revert back to previous firmware which worked fine, or an update to this new firmware to fix the issue. It's ridiculous to not be able to watch Dolby Vision content on my OLED TV.

This is exactly what I did. My receiver supports eARC (Denon X3600H) and I connected the NVIDIA Shield directly to my TV. I’m still able to pass through lossless audio except DTS:X.

LG terminated support for „DTS“ sound, because they decided that the marked share for DTS is too low. Thats what they wrote to a friend of mine last week. One reason more that an AV-Receiver should work fine with the LG tv.

 

After 2 german media websites (golem.de / heise.de) reported about the dolby vision problem, the dolby support wrote me that there will be an update next week, probably monday. And then it should be fixed… hope for the best

This issue has inspired me to do something I planned anyway but was avoiding………moving to an eArc setup completely. 
I did this today and now my ATV, TiVo box and Blu are all connected directly to the TV with one HDMI from the TV to the Marantz sr 7013. After some fussing with settings, it finally all works and I can adjust the picture settings for each individual video input finally. 
Final step was to modify my Harmony Elite remote to reflect no longer needing to change receiver inputs, and needed to change TV inputs. 

Thank you for putting this out there.  I moved to eArc and everything works GREAT, now.  (LG C9 - Denon 3600H)  Place my Firestick in a different port and passing the signal thru the TV, which fixed the problem until a fix is available to run directly.

Very good! Even if LG does issue a fix, I won’t care either way and will leave EArc enabled permanently. Funny that LG’s screwup sort of inadvertently forced my hand to do something I was putting off. Technically, eArc would seem to be the better solution anyway, providing direct connection from source devices to the display and removing a device from the chain (the receiver).  I can confirm after several days of viewing using EArc that the image from any source  looks better on my LC C9 OLED 77”.

Problem in Dolby Vision on LG Oled TVs C9 and CX models after Software update: 05.10.04
Immediately after updating to 5.10.04, it keeps flashing / fails to sync on all Dolby Vision signals from Nvidia Shield TV Pro (2019) via a Denon X4500H. Other reports indicate that this is also true for Apple TV + and XBOX SERIES S/X.

From programmed obsolescence as a crime against consumer relations,
The market is driven by consumer dissatisfaction, which is always looking for the most modern or most functional product. The State grants consumers special protection through Law 8078 of 1990, by listing in its text some infractions against consumer relations. Even though the practice of obsolescence encourages the economy by generating more jobs, due to uninterrupted production by suppliers, it is an offense committed by producers. We conclude that, despite not being considered a crime by law, obsolescence is a harmful practice for the consumer.
The Consumer Defense Code (Law 8.078 of September 11, 1990) establishes, in Title II, of art. 61 to 80, a list of crimes against consumers. It should be noted that this list is not exhaustive, as art. 61 is clear in saying that they constitute crimes against consumer relations provided for in the code, without prejudice to the provisions of the Penal Code and extravagant laws. To avoid any kind of confusion, we have:
“The Penal Code and the extravagant law remain in force, with subsidiary effect. That is to say: if a given factual hypothesis is simultaneously governed by a provision of the CP and another one of this Title II, this one will prevail over that one.” (PAULO JOSÉ DA COSTA JR. AND FERNANDO JOSÉ DA COSTA, Crimes against the consumer, 2nd ed., Atlas, p. 3-4)
In particular, art. 66 indicates that the practice of programmed obsolescence is illegal when it states that it constitutes a crime against consumer relations "to make a false or misleading statement, or omit relevant information about the nature, characteristic, quality, quantity, safety, performance, durability, price or warranty of products and services".

Taking into account that, in the practice of obsolescence, the supplier does not inform that the product already has a predetermined operating period regardless of whether it is in perfect condition or not, we have:
"The supplier's silence on a relevant aspect of the product or service, which for some was equated with an allegation, can also make the verb "omit" focus. In other words: the supplier cannot remain silent when providing information to the consumer, because this is equivalent to omitting”. (ANTONIO CEZAR LIMA DA FONSECA, Consumer Criminal Law, 2nd ed. Livraria do Advogado, p. 162)
Below links with other complaints:

https://www.lgwebos.com/topic/7206-c9-update-051004-can-no-longer-connect-to-dolby/

In other words, it is a problem of the model, worldwide, with general dissatisfaction among gamers, proving that LG acts illegally, against the consumer.
Both Oled C9 and Oled CX can transmit in 4K 120HZ with DOLBY VISION ENABLED.
The OLED C9 has HDMI 2.1 at 48GB of data speed, the Oled CX E C1 HDMI 2.1 at 40GB.
The 3 have current WEBOS, system with updated processor and Artificial Intelligence, same quality and data processing.
In fact Oled C9, it normally produced DOLBY VISION on Xbox Series X, Apple TV + , Netflix and after the update (in the same week that Oled C1 received the fix to support DOLBY VISION in 120hz), it stopped producing content correctly in Dolby Vision. In contact with DOLBY and Microsoft both say that the responsibility for updates is LG.
The complaint and denunciation are registered with links to the case.

I was so excited when I saw this post and immediately downloaded the firmware update from LG, loaded it on a USB, and successfully updated my TV. I am still having the same issue with Dolby Vision causing a constant black screen flashing on my LG B9. Apple TV 4K (not 2021) and Denon receiver.

Guess I need to wait for the next update...

Please call LG support and let them know that the new firmware did not fix it.

Also, consider using an eArc setup where all your video sources go right into the TV and the TV sends the audio via one cable to your receiver. Both receiver and TV must support eArc.  I did it and now LG can’t mess with me!

That is how mine is temporarily setup. Plex --> NVIDIA Shield 2019 Pro --> LG C9--> Denon X3600H.

There are a couple of drawbacks for me:

  1. No Denon on-screen volume display.
  2. DTS-X audio does not pass-through the TV to the AVR. Highest I get is DTS Neural:X

Make sure your gear is compatible with eArc…..not just Arc. My eArc setup is passing all audio formats including lossless (Dolby True HD etc.) Make sure your cable from TV to receiver is high-speed with Ethernet. 
As for the volume display, I just use my ears. If someone complains, I turn it down. 🙂

I will add that there is, to my eyes, a bump up in video quality since I connected all video directly into the LG C9 instead of the receiver.

Updated from 05.10.14 to 05.10.15 via USB and no improvement. Unwatchable with dolby vision as it goes black once a minute or more, impossible to enjoy a film like this.

 

Shield Pro 2019 -> Denon x1600h -> LG C9 (OLED55C9PLA)

 

Tried a Dolby Vision title using Netflix on the LG C9 directly seemingly without issue (didn't test on 5.10.14 so can't tell if that's different).

Really not good enough since they don't let us "down"grade our TVs anymore.

Or, maybe it’s time to go with an eArc setup, assuming your gear is compatible.  Worked for me and I’m not going back. Use the TV as your video switcher instead of the receiver. Use the receiver for sound only.  Sorta like the old days!

Perhaps it is but it'd be a shame. It'd take up my last HDMI port to move the Shield to the TV and eventually that'll be a problem when I have 3 120hz 4k devices needing attaching.

I agree with you. The problem is, with ever-changing standards for audio, video, HDMI etc., it’s getting harder and harder to guarantee compatibility between components, especially of different brand names. You’re only an update away from breaking something. And I doubt LG loses much sleep over playing-well with competitors’ gear.

I doubt they do lose much sleep but it's a huge issue in my books. If it isn't fixed promptly I'm definitely going to think twice about trusting them for the next TV if I can't rely on a very common set up working, can't choose to roll back updates on my own tv, and has more adverts in the newer UI. It's not like somebody else changed anything either. This was LG pushing an Advertising based update and breaking a useful feature in the process. The update they've pushed hasn't fixed it and they don't allow me to fix it myself with their own proven to work software..

05.10.15 works for me.:  Apple TV 4K (Second Edition) >>  Denon X3300 >> LG C9.   DV works again - no flashing, black screens, etc.

You may want to check for a Denon firmware update.  A day or two after this problem occurred I received an OTA FW upgrade for my Denon.  There is a post in the AVS Forum that some AVR's may need a FW upgrade too.

Mine worked immediately after I updated the TV.

After the latest update,  05.10.15, I’ve  have most functionality back most of the time. However, occasionally  Apple TV 4K looses Dolby Vision, I’m also seeing white lines through picture occasionally.  Denon 3400h, LGC9, ATV 4K

I installed 05.10.15 my C9 two days ago and now I see juddering with my Nvidia Shield Pro TV 2019 regardless of the setting in TruMotion.  Off, Smooth, Clear or even User mode I get the juddering.  But the juddering isn't present if I use the built-in WebOS app.   The problem doesn't seem to appear with Comcast's Flex box, either.   Model: OLED65C9AUA   I rebooted my Shield and the problem still continues.  But as far as I can tell, no updates were downloaded on the Shield.  I had the Shield since its debut in 2019 and never had problems with it before.

      hi all. new to this but really stumped!!! i live in ontario canada and have been using cogeco cable for internet and tv. it got way too expensive so i cancelled both and switched to bell 3.0 which is at least 3 times faster and we have no tv package, so we are just streaming everything for 1/3 the price!!!!!  i signed up for a couple of sports sites, tsn and sportsnet + so i can watch hockey playoffs and other sports.  tsn works just fine on the tv.  however, sportsnet + says that i have to have web os version 89 or higher.  i found my tv, which is a 2023 version, is only version 87!!! i chatted with tech support and they were no help.  anybody got any ideas as to what i can do for this???  no auto software updates for it and nothing on the lg app store.  quite confused how a 2023 model is not up to date, or sportsnet+ is that far ahead and not backward compatible>>>
      thanks to anybody that answers.

      Space has the power to shape both the perception and perspective of our experiences. Fueling everyone’s passion for interior design is the emotional influence of our surroundings and our appetite for aesthetics. From the uninitiated to the aficionado, we make conscious efforts to reflect who we are through our home decor. Interior design trends are inspired by cultural events and, at times, are reactions to movements in popular culture. With such powerful actors, maintaining balance and introducing elements that complement rather than overpower are gaining value. This is especially important when it comes to integrating essential yet potentially disruptive elements like the TV into a room’s decor. Fortunately, LG has devised a solution that resolves this dilemma while letting people stay true to their distinctive style.
      With LG OLED M, the TV is no longer the interior designer’s nemesis but a tool to elevate the décor and tailor spaces to modern lifestyles through its seamless integration. Compact and discreet, the elegant OLED TV with the Zero Connect Box is the only OLED TV that can send both 4K 120Hz video and audio wirelessly, helping homeowners free their TV from cables and external devices and gain the freedom to achieve their dream living spaces.

      More Space for the Things You Love
      Feeling overwhelmed by the mess around your TV screen? Visible cables and bulky furniture can take up valuable space much to the frustration of the designer. A cluttered space not only disrupts the balance of sophistication and functionality they worked so tirelessly to curate, but it also limits their ability to express a distinctive personal style through their home design.
      LG OLED M with the Zero Connect Box declutters the TV area by banishing tangled cables and external devices to more discreet locations like on a side table, bookshelf, cabinet or coffee table – practically anywhere the designer sees fit. This feat also eliminates the need for a bulky TV unit or cabinet which often disrupts the room’s design, freeing up space to display ornaments, paintings or maintain a simple look.

      With the maximalism trend growing, where every inch of space is carefully considered in the overall aesthetic, the Zero Connect Box emerges as a versatile solution. By eliminating tangled cables and external devices around the screen, homeowners can enjoy newfound freedom to experiment with placement, colors and textures, helping them build the aesthetic harmony they desire.
      The TV for Sophisticated Simplicity
      As more designers embrace the quiet luxury trend, which champions effortless elegance over the risk of being ostentatious, the LG OLED M and its Zero Connect Box has become the ideal companion to realize a home of understated sophistication. Creating a cohesive look through muted tones, refined finishes and simplicity under the quiet luxury concept, the LG OLED M elevates the elegance of a living space with the Zero Connect Box. A nightmare for designers seeking to develop a space that looks luxurious but not overly so, cables and clutter limit their design freedom as they must be hidden by more furniture.

      With the Zero Connect Box, it’s easy to inject luxury into the TV area in an understated and effortless way, simplifying the space by removing unnecessary clutter. And thanks to the OLED screen’s sleek, ultra-thin design, it mounts flush to the wall to resemble a sophisticated picture frame that blends into the décor instead of taking attention away from it.
      Hassle-Free Flexibility
      With the Zero Connect Box, designers are no longer tied down by the length of their TV cables or the placement of furniture. They can be more strategic with their floor plans. The Zero Connect Box unlocks new room layouts without the hassle of rewiring or moving heavy furniture. Want to rearrange the furniture for movie night or update the interior with the seasons? No problem, as the LG OLED M can be moved around the room with ease as it eliminates the hassle of untangling, disconnecting and reconnecting multiple cables.
      Another major benefit of the Zero Connect Box is how it allows users to effortlessly connect or disconnect devices without having to reach behind the screen or wrestle with cables – which also pose a trip hazard. It gives the user the power to place their Zero Connect Box anywhere within reach of a power cord, and therefore the ability to manage all connected devices in a more convenient and well-organized space.
      A Home Theater for Every Occasion
      Another home trend emerging in recent years is a home theater that adapts to modern living. With LG OLED M, home designers can create a home cinema that doubles as a gaming room. In this space, the console or Blu-ray player, which light up when in use, can be placed out of view instead of under the TV to minimize distractions and maximize immersion.
      LG OLED M mounts flush to the wall while its Zero Connect Box transfers video and audio wirelessly to the screen, so what the viewer sees ahead is just the OLED TV. This makes it easier to appreciate the incredible self-lit picture quality of the OLED screen, which facilitates higher immersion thanks to less distractions between them and the display.
      What’s more, LG OLED TVs not only deliver perfect blacks and offer large screen sizes, but they often perform better than projectors in brighter environments, so the room doesn’t have to be pitch black to achieve the level of immersion gamers live for.

      Since the last webos update to 3.40.87, I find I have to completely power cycle the TV (a G1 65" OLED) every week or so to get the DLNA client back to functioning properly. I have a media server running Serviio on a Raspberry Pi, and I periodically get one of the following two problems, both of which are fixed by completely power-cycling the TV.
      When I'm using the DLNA client to select videos from the server, I get no response from trying to select a video or series using the remote. The remote continues to work fine when used with other apps (eg Netflix, Stan etc) on the TV. When the DLNA client is playing a video from the server, the audio is delayed by a couple of seconds from the video. At the time that the TV is showing either of these problems, I can access the media server using either BubbleUPnP on my phone or VLC on my PC, and neither of them have any problem either selecting videos or playing them back with the audio synced with the video, so the problem is clearly with the TV, and power-cycling the TV gets rid of whichever problem is manifesting itself.

      webOS updated, I think to 2023, on my C2 a couple of days ago. Since then the News option on the Sky News app no longer works, instead timing out. The Weather and Climate options still work, though.
      I have deleted and reloaded the Sky News app, but the problem remains.
      Does anybody have any suggestions of what I might try to get this working again, or is this something for LG, or Sky, to fix?
