Your TV crops the edges of movies and cuts off subtitles because overscan is turned on. Overscan is a picture setting that slightly enlarges the image and pushes the outer edges off the screen. It affects cable boxes, game consoles, Blu-ray players, and streaming sticks connected by HDMI. It can also hide score bugs, news tickers, and subtitles placed near the bottom edge.

Why does overscan exist?
Broadcast television once needed overscan to hide flickering lines and signal noise at the frame edge. Tube TVs could not display the full frame cleanly, so makers zoomed in by a few percent. Flat panels do not need that fix, but many sets keep overscan on by default.
Standard picture modes often apply it automatically, especially on HDMI inputs labeled as cable or video. Films make the crop more visible than TV shows do. A 2.39:1 widescreen image, two black bars above and below a very wide picture, loses side detail first, then titles and subtitles.
How do I stop the cropping?
Look for a picture-size control in the TV menu. Makers use different names for a direct one-to-one picture, including Just Scan, Screen Fit, 1:1, Full Pixel, Dot by Dot, or PC mode.
Use these steps on most sets: Test with a movie that has thin letterbox bars and small on-screen text. Pause on a wide shot with faces near the frame edge and subtitles on, then switch modes and watch the edges return.
- Open Picture or Display settings for the HDMI input you use for movies.
- Change Picture Size, Aspect Ratio, or Overscan from 16:9 or Auto to Screen Fit, Just Scan, or Full.
- Turn off any extra zoom, stretch, or edge-crop option.
- Save the change for that input, then check another input separately.
What if only subtitles are cut off?
Some subtitles sit very low in the frame, partly inside the lower letterbox bar. Even a small zoom can clip them while the main picture looks normal. Check the subtitle settings in the app or disc player first.
Many players let you raise subtitle position, shrink the font, or switch from image subtitles to text subtitles. Also check the player output resolution. A player set to 720p on a 1080p or 4K set forces extra scaling, which can soften text and worsen edge loss. Match player output to the TV resolution when possible.
When is the crop part of the film itself?
Not every tight edge means your TV is wrong. Directors often compose for a slightly narrower theater frame, and home versions may trim small slivers for broadcast-safe titles, text that must stay inside the visible area. Aspect-ratio differences can look like cropping too.
A 4:3 classic, a nearly square old film, shown stretched to fill a widescreen TV will lose top and bottom. A CinemaScope epic shown in 16:9 pan-and-scan, a reframe that follows the action, loses the sides by design. Compare the same scene on another screen or switch the TV to its direct-pixel mode before judging. If bars look even and text has breathing room on one input but not another, the tight input still has zoom or overscan on.
