Screen Uniformity Test — Check Brightness & Color Balance
Inspect luminance distribution and color temperature consistency across all 9 screen zones using full-field test swatches and optional 3×3 inspection grid overlays.
Uniformity Inspection Protocol
- 50% Gray Field: Best pattern for exposing Dirty Screen Effect (DSE) and edge vignetting.
- Solid White Field: Best pattern for spotting color temperature shifts (e.g. pinkish or greenish tinting in outer corners).
- Solid Black Field: Exposes backlight bleed clusters and panel clouding in dark environments.
Frequently Asked Questions
What is display luminance and color uniformity?
Uniformity measures how consistently a monitor maintains identical brightness (luminance in nits) and color temperature (Kelvin white point) across its center, edges, and four corners.
What is the "Dirty Screen Effect" (DSE)?
Dirty Screen Effect describes visible blotches, vertical banding, or cloudy patches on screen that make solid backgrounds (such as hockey ice, sky, or gray fields) look like dirty smudged glass.
How do I use the 3x3 Inspection Zone Grid?
Toggle the "3x3 Zone Grid" checkbox below the test stage to overlay subtle dashed boundary lines dividing your display into 9 standard calibration quadrants (Center, Top-Left, Top-Right, Bottom-Left, etc.). Compare luminance across opposing quadrants.
