I'm nervous as I'm getting used to plugging my Shield into the C9 rather than my AVR. I don't want things to get worse. I'll wait for others to install it first and provide feedback.

Firmware v05.10.25 was just released in South Korea and for ATSC models. I haven’t tried it yet. Hoping this release resolves all DV issues.

I just noticed 05.10.15 on the LG's UK site dated 06/30/21. Anyone yet installed it? https://www.lg.com/uk/support/software-firmware?csSalesCode=OLED55C9PLA.AEK

Please ignore. Blanked out for a moment. Not sure why I thought 05.10.15 was brand new.

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.  

All my HDMI cables from Plex to TV and TV to AVR are BJC Series-FE Bonded-Pair High-Speed Premium HDMI Cable with Ethernet, 12 Foot, Black

Lossless audio like Dolby Atmos, Dolby TrueHD, and DTS-HD work except for DTS-X.

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

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.

Other are starting to report that the flicker, a little bit less, is still present with 05.10.15 firmware.

Updated to 05.10.15. Multiple DV contents from Plex still flickering for me. 

Plex --> NVIDIA Shield 2019 Pro --> Denon X3600H --> LG C9.

As more update, we'll see if it is just me.

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. 

I did exactly what you did, but realized that the on-screen display of the volume from Denon is no longer displayed. Not a big deal. Not sure if the Marantz has the same behavior.

Well, the plot thickens. 
LG Support yesterday advised that I could simply initialize the C9 TV to get back to factory settings, including the original OS. Not so. All settings will be put back to factory but you will still have whatever OS you had before the reset. 
I told LG Support this and their response was I might need to have my control board replaced. 

‘Huh?

I’m thinking about perhaps enabling eArc instead and connecting video sources (ATV etc.) directly to the C 9 and then eArcing the audio to my Marantz 7013.

Don’t think I want a service tech opening up my 77” TV that’s less than a year old to replace a control board that probably works fine.  An improved software update from LG would be much preferable. 

 

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.
