I upgraded to a Apple 4K TV and now have this dark section running across horizontally in the picture. This is fixed by restarting the Apple TV but over time it reappears.
What setting needs adjusted to eliminate this?
Apple TV 4K, tvOS 12
Try another HDMI cable (make sure it is capable of 18GBPS for 4K/HDR).
Try another port
Make sure TV is correctly set for HDR
Test on another TV
Try a restore
