DISPLAY TEST
Sharpness Test
Check text clarity, fine-line definition, edge sharpness, pixel separation, scaling artifacts, and visible oversharpening using detailed fullscreen reference patterns.
Fine Horizontal Lines
The thin horizontal lines should remain clearly separated without
excessive blur, halos, or merging.

Visual Sharpness Reference
Browser zoom, operating-system scaling, display scaling,
anti-aliasing, panel resolution, browser rendering, and image
processing can affect these patterns. For the most useful result,
use 100% browser zoom and the display's recommended native
resolution where possible.
