LG webOS Add-Ons & Accessories

Rebooting ATV does not fix it. Look at your ATV video settings I be it is not set to DV. I will say that the TV somehow switches to DV only when you watch DV formatted movies. Hulu an other non-DV content still looks like crap. Too dark and when you set it to Vivid it’s bright but distorted.

I had exactly the same issue with the update. Dolby vision flashing on and off using Apple TV 4K box. Restarted the Apple TV box and all issues seem to be fixed hope this helps.

If I connect directly from the ATV4 to the LG - DV works fine.  Also, if I connect thru the Denon when it is in standby (Apple video is set as a pass thru to LG) DV works fine.  It's only when the Denon is on do I have an issue.

Yep, Dolby Vision, that is why it was notable to me.  Basically some places Dolby Vision is fine (my UHD player) and some not fine (Apple TV 4K).     have not tried a disc in my PS5 or XSX, will try that later.

Lg cx Can't play/pause in browser any more with remote. Screen server keep coming while watching. What's going on? Before update was everything fine. 

You may want to check this user post in the AVSFORUM:   He said in a previous post LG is aware of the issues and is testing a fix now:   link hidden, please login to view The above user is credible. FWIW:  When we started up our ATV4 > Denon > LG C9 system last night we were offered an update to an older Denon AVR-X3300W.   Firmware Version:  8700-4058-9140.  I updated to that version.  There was no information as to what was in it.  I suspect this is Denon's fix on their side. Waiting now for LG's fix.

Opened a case today, 19-Jun-2021, with LG support. Some additional information: - My setup:  internet <- cat5 -> Roku Ultra HDR 4K UHD  <- HDMI -> Denon AVR-S960H <- HDMI -> LG OLED - I'd recommend using LG chat. Email results in typical "reset this, reset that". You'll need model and serial number of TV.  Email response from LG stated that chat is only open M-F. but someone did respond today (Saturday). Open cases! - I had the LG rep add the link to this thread to the escalation ticket.
