Apple TV 4K is designed to give you the best viewing experience based on the capabilities of your 4K television. By default, Apple TV 4K matches the dynamic range to the highest refresh rate that your television supports. For example, if your television supports Dolby Vision at 30Hz, but also supports HDR10 at 60Hz, Apple TV 4K will use HDR10 instead of Dolby Vision.
In tvOS 11.2 and later, you can configure your Apple TV 4K to automatically switch your display format to match the original dynamic range and frame rate of content you're viewing instead of using the highest capability of your television. For example, your Apple TV 4K will use HDR10 at 60Hz when viewing HDR content, but will switch to Dolby Vision at 30Hz when viewing content that supports Dolby Vision.
To enable this feature, go to Settings > Video and Audio > Match Content, then choose from the following:
- Match Dynamic Range: Turn on to have Apple TV 4K match its output to the original dynamic range of content that you’re watching.
- Match Frame Rate: Turn on to have Apple TV 4K match its refresh rate to the original frame rate of content. This applies to content that's mastered at different frame rates, for example 24fps film-based content or other international content.*
If you turn on either of these settings, Apple TV 4K will attempt to automatically determine which dynamic ranges and frame rates your television supports.
If Apple TV 4K can't determine which display formats are available, you'll need to verify which formats your television can display. To verify a format, go to Settings > Video and Audio > Match Content. Then select a format under Unverified Formats to run a short display test and verify that it displays correctly on your television.
*Apple TV 4K will match the frame rate of content encoded at 60, 50, 30, 25, and 24fps. Frame rates will match the refresh rate appropriate for your region, for example 29.97fps for NTSC. 25fps and 30fps content uses frame rate doubling to display at 50Hz and 60Hz when available, matching its original appearance while preserving a fluid user interface.
When you use content matching, your television will switch dynamic range and frame rate based on the content you’re watching. You may experience a blank screen or flickering as your television switches between formats.
