Note: Not all videos include closed captions.

In Settings
on Apple TV, go to Accessibility > Subtitles and Captioning > Style.Choose an existing caption style, or create a new style based on your choice of:
Font, size and colour
Background colour and opacity
Text opacity, edge style and highlight
Note: If you connect a Braille display to Apple TV, it will continuously print the captions and subtitles of a TV show or movie when captions or subtitles are turned on.
