Professional Calibration Tools
Multi-temp white point
D50/D55/D65/D75 side by side to match the white point target of your environment.
24-patch chart
A ColorChecker-style chart covering skin tones, naturals and saturated primaries.
Grayscale first
Verify neutral grays before calibration — tinted grays make calibration pointless.
Calibration Essentials
ΔE
Color error unit. <1 invisible, <2 professional, >5 obvious. Calibration usually targets ΔE<2.
ICC profile
A file describing display behavior. macOS applies globally; Windows only in color-managed apps.
Color management
The file-to-screen conversion chain; wide-gamut screens oversaturate without it.
How to Use
Confirm grayscale
Check grays are neutral; if tinted, fix OSD RGB gains first.
Match white point
Show D65 fullscreen, compare to white paper, adjust temperature to match.
Verify with chart
Review skin tones and saturated patches on the 24-patch chart; use a meter for precision.

Optimization Tips
Warm up 30 minutes and set brightness near 120 nits before calibrating.
Keep ambient light constant and neutral — results are valid for that environment.
Recalibrate quarterly; LCD backlight aging drifts the white point slowly.
Generate separate ICC profiles for each display in a dual setup.
FAQ
Calibration Environment
- Neutral gray surroundings (no colored walls)
