Rebooting ATV fixes nothing of course, that's probably one of the first step people will take.

Last night, I got the black screen once... in HDR after 2 hours. So the problem also exists to some extent in HDR. Dolby Vision being 1000 times worse of course. I have a Denon AVR.

On the Denon, if you enable "Pass Through" of the ATV while in standby mode - you can select Dolby on the ATV and the C9 accepts.

Guessing LG made a change that affects HDMI communication with the Denon since it was working fine immediately prior to the update.

I have a ticket open with LG - they said their sofware enginners would get back in a couple of days.  If I get a resposne i'll post it here.

 

Enabling pass through of the ATV, I still got a black screen after 3 minutes of watching a video. Seems random, could be every 30 secondes or every few minutes.

Hi, I have the exact same problem, also going through a Denon AVR.

The update broke something, always worked fine until then. I hope the issue gets to LG so they can fix it quickly but until now support blames my internet connexion (fiber lol) and refuses to acknowledge the problem...
