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
