I have an LG OLED B3 and Apple TV 4K. I am using a brand new ultra-high-speed HDMI cable and have also tested other cables and HDMI ports. My Apple TV is set to 4K SDR with content and frame rate match on.
When I play some Dolby Vision, mainly on Infuse, the screen goes black every 30-60 seconds and the Dolby Vision logo appears in the right corner, and then the vision comes back. I’ve played different Dolby Vision content and it does not happen on all content (eg. Netflix), but more than 50% of what I play has the issues.
The only thing that fixes it is turning off ‘match frame rate’ on the Apple TV side or HDMI Deep Colour on the LG side. I would prefer to keep these options on. I also tried to turn off Trumotion completely, and it doesn’t fix it either.
I had a Sony 4K TV before this and did not have these issues.
Does anyone know how to fix this?
