Professional Monitor Color Test
12-color cycle
White, black, RGB, CMY, yellow, orange and three grays — cycle with ←→ or swipe.
Custom HEX
Enter any HEX value for fullscreen display to reproduce the exact color you care about.
Uniformity check
Large solid areas are the best way to spot patches, dirty screen and tint drift.
Color Check Essentials
Color cast
Gray/white leaning yellow, blue or green — usually temperature or channel gain settings.
Uniformity
Brightness/hue varying across the panel; 50% gray is most sensitive, edge falloff most common.
Saturation
Washed-out colors mean low gamut coverage — typical of 45% NTSC entry panels.

Go fullscreen
Click the swatch or press F; ←→ cycles the 12 colors.
Check each color
Hold 5 seconds per color, watching for patches, tints and dark corners.
Custom HEX

Optimization Tips
Fix white cast via the OSD temperature preset (6500K is standard).
Load the correct ICC profile on Windows/macOS for instant improvement.
Edge tint beyond 20% is a uniformity defect — exchange new units.
