How to Setup Your Apple TV
You should configure your Apple TV to be in HDR mode (not Dolby Vision HDR) and for the refresh rate to match the frame.
By default your Apple TV will be set to 4K HDR (HDR 10). You should change the resolution to 1080p. The refresh rate is also set to 60 (59.94Hz) or 50 depending on your region. It’s fine to run at this refresh rate, but if you want true 24fps, for example, then you should switch to 24Hz.
Here is an example of how to set your dynamic range on your Apple TV to be HDR and to match a source frame rate of 24fps for true 24fps.
Open the settings App from the main menu
In settings, click on the “Video and Audio” menu entry
Click the format menu entry and scroll down to the bottom. Click “Other Formats”
Scroll down to the bottom to select 1080p HDR 24hz
Confirm the new setting by clicking “OK”. Your screen might turn black for a few seconds depending on what it was previously configured to.
