Match frame rate on Apple TV HD and Apple TV 4K

Use Apple TV Match Frame Rate to compare steady judder with normal cadence and separate a refresh-rate switch from a sustained playback stall.

Listen to the rhythm of the problem

Look at a slow camera pan or a scrolling banner. If motion hesitates at a regular rhythm while audio and playback continue, test frame-rate matching. A spinner, long frozen frame or changing quality points toward a different investigation. When you compare modes, use the same scene on the same HDMI input and leave television motion smoothing settings alone.

Apple’s Match Frame Rate setting is available on Apple TV 4K and Apple TV HD under Settings → Video and Audio → Match Content. It requests a suitable output refresh rate for the programme. The app and display still need to support the route.

An example of uneven cadence

In a simplified 24-frame-per-second film shown at 60 refreshes per second, 24 does not divide 60 evenly. A repeating pattern can hold some source frames for two refreshes and others for three. The video can be fully downloaded while a pan still appears uneven. At a compatible multiple of the source frame rate, frame holds can be more even.

A live programme can use 50 or 60 frames per second depending on how it is produced. Check the actual programme rather than assuming every title in a player uses the same cadence. A device might also identify fractional rates separately from their rounded labels.

Save a working baseline

  1. Record the current format and match settings before changing them.
  2. Switch Match Frame Rate on and restart the same programme or repeat the same scene.
  3. If the television blanks briefly, check whether video returns and the TV reports the new format.
  4. If the signal remains lost, return to the working format and test the cable or receiver before attempting other changes.
