A sharpness control emphasises edges but does not add original detail to low-resolution media. If text or faces have bright outlines, compare a lower supported value using the same scene. Keep resolution and picture mode unchanged. Examine subtitles, fine lines and natural texture rather than only an initial distant impression. The aim is a clean picture, not maximum enhancement, and a stronger edge should not be confused with additional information in the source.

Why it matters
Processing can increase apparent definition while exposing compression or other artefacts. That differs from real source detail. A repeatable scene lets the viewer judge the control itself, with programme differences removed from the comparison as far as practical.
Work through the steps
- Record mode and sharpness value.
- Revisit a scene with text and natural texture.
- Change only sharpness through supported controls.
- Compare outlines and ordinary viewing comfort.
What to avoid
Do not use maximum enhancement as a substitute for better source detail. Avoid changing noise reduction, contrast and resolution simultaneously. The resulting picture may look striking while making the specific cause impossible to identify.
The useful takeaway
Judge the displayed result rather than the setting number. Readable, clean detail is useful; no edge control can reconstruct information that the source did not contain.
