Identify where the programme originates
Note whether you are using a native app, TV input, USB player or external HDMI device. Samsung documents picture-size controls for particular source types and model conditions. A setting available on one input need not apply inside every app.
Record the current picture-size value before adjusting it. Use a reference that includes recognisable edges or on-screen controls so you can tell whether content is being cropped or merely letterboxed.
Compare the source and television stages
If an external player is connected, inspect its documented aspect or output controls too. A crop performed by the player cannot be fully understood by looking only at the TV setting. Avoid changing both devices at once.
Start with the source's normal presentation and a supported TV fit option. Watch the shape of faces and circles as well as the edges. Filling the screen at the cost of distortion or lost action is a different outcome from preserving the intended picture.
Treat an unavailable option as information
Check the exact model manual and the current signal conditions. Samsung notes that functions such as Fit to Screen have availability qualifications. Do not use an engineering or service menu to force a consumer control into an unsupported state.
If only a native app lacks the control, consult that app's playback settings and support. A different input working normally narrows the issue but does not make the app follow the same scaling path.
Verify after the change
Check programme edges, subtitles and the player overlay. If the controls themselves are cut off, record that separately from black bars inside the programme. A source may contain its own bars as picture pixels.
Send support the TV model, source, input signal and before/after setting. This workflow uses documented control scope and does not measure a broadcast's original aspect ratio or promise identical settings across all Samsung televisions.
Keep menu crop separate from programme bars
If the application's own buttons disappear beyond the screen edge, use the whole interface as the reference. If only the film contains black bars while menus fit, the source framing may be intentional. Photographing the setting and describing the clipped control can help support; a camera photograph should not be treated as an accurate measurement of the programme's original geometry.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
