Applies to: Sony display with documented normal/full/wide modes; use an owned square-grid and circle reference of known proportions.
The useful distinctions
- Sony’s legacy screen guide distinguishes original 4:3 display from horizontal enlargement.
- Its screen choices depend on model and signal.
- The guide provides separate zoom and wide-format behaviours.
Choose geometry you can trust
A face may look unfamiliar for many reasons, while a known circle gives a clear proportion reference. Use a file you created or whose intended dimensions are documented. Keep the player’s own sizing unchanged while testing the TV. If the player already distorts the reference, the television comparison cannot establish the original file’s geometry by itself.
Inspect shape and coverage together
Write down whether the circle becomes wider or taller and whether the border remains visible. A mode can preserve shape while cropping edges, or keep edges while introducing bars. These are different outcomes. Describing both avoids calling any setting “correct” just because it uses more of the screen. The fit choice should follow the purpose of the material.
Limit the model claim
The cited legacy Sony screen guide illustrates documented mode behaviours for its own range. It does not establish identical labels or features on a modern television. Use the exact manual to find an equivalent supported comparison. Once proportions are understood with the reference, return to the programme and check its published aspect information before attributing an unusual composition to the player.
A focused way to proceed
- Display an owned reference whose circles and squares have known proportions.
- Record the current player fit and TV screen mode.
- Change only one documented display fit choice.
- Compare circle shape and edge visibility.
- Restore the original state and repeat once.
Worked example · synthetic
Hypothetical example: a known circle becomes a horizontal oval when a documented 4:3-to-full enlargement is used, while its corners remain visible. Restoring original-size display returns the circle’s shape and adds sidebars, making the trade-off explicit.
When to stop or ask for help
Do not apply a legacy model’s labels to another TV. This visual test does not recover a source aspect ratio whose provenance is unknown.
