Apple TV does not display the full screen.

I use Zwift on Apple TV and there are times that I mirror stuff from my iPhone or my laptop. In all cases, the full image of the application or the mirrored content is not displayed. There is a bit on the top and bottom that is cut off. I've tried all the settings I can think of but nothing has changed the situation.


How can I remedy this?


Thanks

Apple TV 4K, tvOS 15

There is a setting how AirPlay should be handled for non-matching aspect ratios.

Settings﹥AirPlay and HomeKit﹥AirPlay Display Underscan﹥On|Off|Auto

“On” uses black bars to fill if needed (Underscan). “Off” crops to match if needed (Overscan). I have no idea how ‘Auto’ works, or how it can be any good, as it depends on content.
