Open a programme with an available subtitle track and test it from the normal viewing position. Check language, timing, size and the lowest line on screen. A television’s accessibility setting may not control every third-party player in the same way.
What matters here
Caption availability depends on the actual source, while styling depends on the player and platform. Picture zoom can crop text even when the subtitle setting is correct. Distinguish a missing track from text that is present but hard to read.
Work through these checks
- Choose the intended available subtitle or caption track.
- Review supported app and system appearance controls.
- Check picture-size settings if text is cut off.
- Compare another programme to determine whether the issue is source-specific.
Avoid this mistake
Do not promise subtitles for every title merely because the TV has a caption button.
