Screen Uniformity Test – Fullscreen Check
Checkerboard and gradient patterns to detect color banding, brightness inconsistency, and display uniformity issues.
What to Look For
- • Color banding — visible steps in gradient areas instead of smooth transitions
- • Clouding — uneven brightness patches (common on LCD panels)
- • Dirty screen effect — smudge-like patterns, especially visible on gray
- • Edge glow — brighter areas along screen edges (backlight bleed)
Test Patterns Available
- • Checkerboard — classic uniformity test pattern
- • Gray gradient — detects color banding
- • RGB gradient — tests each color channel uniformity
- • White/Gray/Black — solid colors for quick uniformity check
