Apple TV 4K Graphics scaling problem

Hi,

I tried to use my monitors native resolution 1920x1200 with Apple TV 4K. Upper part of the screen does not appear.

Projectors can be wonky. Did you set the Apple TV to the 1080p setting, or the Projector, or both? EDIT: Don’t ask me why you said projectors.  Eek.

Try changing your ATV’s video resolution to something other than 1080p or 720p.

I had the same problem, so I changed my resolution to 1390x768 and the scaling problem went away.

You might also be able to adjust that on the TV itself.  Look for overscan settings.
