Per the title, anyone else seeing issues with Dolby Vision in the latest tvOS 13 beta 3 ? For me this has always been working (even in beta 2) without any issues but now it fails to show the screen and I have to have the ATV 4K re-scan, fail and take it back to regular HDR mode. My setup has and does support Dolby Vision without issue to this point and the cables are known good. Whats funny is this was working fine after the beta update for a few hours then now will not switch into it.
Anyone else seeing this or have any ideas ?
ATV4K -> Receiver -> LG OLED TV
Bug/Feedback filed as well
You don't say which app you are using to watch the movie but if it's the TV App try using the iTuines Movie App and see if you have the same issue. I've heard many reports of DoVi issues with the new TV App. Using iTunes Movies is the workaround for that.
