Did you know you can change the appearance of your subtitles on your Apple TV? While the ability to do this isn’t entirely new — it first came to the second- and third-generation Apple TV models two years ago — users of the new fourth-generation Apple TV may find it particularly useful now that subtitles are more readily available via Siri commands like “What did he just say?”
You can find the option for this in the Settings app, under General, Accessibility, Style.
Three built-in styles are provided — Default, Large Text, and Classic — and each will show a preview on the left side of the screen when selected.
If none of the pre-defined options strike your fancy, you can use the Edit Styles option at the bottom to create and save your own custom style with options for choosing text font, size, and color, background color and opacity, as well as more advanced text opacity, text edge style, and text highlight settings.
