Cropped subtitles can come from TV overscan, player zoom, subtitle placement or an incompatible style. Check the overall picture framing before moving every caption. A global crop can also remove scoreboards and other edge graphics. Look beyond the caption line: if a score graphic or playback bar is also cut off, the entire image may be cropped. If only text is affected after full-picture framing is restored, investigate caption margins, size and source styling next.
Reset zoom first
Original framing helps isolate the cause. Return the player's ratio, zoom and crop controls to their recorded original values before changing subtitle placement. A zoom selected for a wide film may cut into the bottom of a different programme. Compare a scene with two caption lines and a recognizable edge graphic. If the full picture returns after resetting crop, keep that correction separate from any later text-size preference so the same framing problem is not hidden by tiny subtitles.
CheckTV fit
A screen-fit mode may restore the full image. Open the TV's picture-size setting for the active input and select its documented exact-fit option where appropriate. The names vary, and some choices depend on the incoming mode. Check all four edges using a reliable reference rather than moving captions upward immediately. If player menus and channel graphics fit correctly after this step, the remaining issue is more likely to be local subtitle positioning or an individual track's layout than global display overscan.
Adjust text safely
Use supported placement and size controls for remaining issues. Use supported subtitle margin and position controls, checking both one-line and two-line cues. Extremely large text can wrap into additional lines that exceed the available space, while source styles may request a position the player handles poorly. Compare another supplied text track if possible. Retain a readable size and suitable outline or background; shrinking captions until clipping disappears can create a different accessibility problem without explaining why the original boundary was wrong.

An example to work through
A zoom setting removes the lower caption line while also cropping the top score graphic. The bottom line and the player's progress bar are both missing until the TV input leaves zoom mode. After the full image returns, a modest subtitle size remains readable, showing why reducing the text alone would have concealed a wider cropping problem.
Questions about this topic
Does this mean the subtitle file is incomplete?
Not necessarily. Valid text can be present but rendered outside the currently visible picture boundary.
Should every caption be made tiny?
Fix framing before reducing readability. Correct the framing and margins first, then choose a size that remains comfortably readable.
