If faces look stretched or captions are cut off, inspect the player fit mode and the TV’s aspect-ratio controls. Preserve the source proportions rather than forcing every programme to fill the panel. Menu options can differ by input, app and model year.
What matters here
A built-in app and an HDMI streaming box may use different picture settings. Test the actual viewing source after a change. Black bars can be correct when the programme’s shape differs from the screen; removing them can crop useful picture information.
Work through these checks
- Identify whether playback comes from a built-in app or HDMI device.
- Check the player’s fit or zoom selection.
- Review the TV’s supported aspect-ratio option.
- Compare a familiar scene and the lowest caption line.
Avoid this mistake
Do not assume a setting changed on one HDMI input applies to every built-in app.
How to judge the result
The correct result preserves natural proportions and keeps relevant text visible, even when some unused screen space remains.
