Versions:
DisplayCAL 3.9.17 is a Windows color-management utility designed for calibrating and characterizing monitors, televisions, projectors, and other display devices with laboratory-grade accuracy. Built around the open-source ArgyllCMS engine, the application reads raw spectral data from a wide range of supported colorimeters and spectrophotometers, then generates ICC profiles that precisely describe each screen’s color response. Professional photographers, pre-press operators, broadcast colorists, and enthusiastic home users rely on the program to achieve consistent hue, gamma, and white-point across single or multi-monitor workstations, to verify the validity of existing profiles, and to create 3D lookup tables for video color grading suites. Advanced options include CIECAM02 gamut mapping for changing ambient-light conditions, custom test-chart editors for arbitrary patch counts, synthetic profile generation for special working spaces, uniformity measurement grids that reveal luminance variation over the panel surface, and importable colorimeter correction tables that raise absolute accuracy when the instrument is used on LED, OLED, or wide-gamut backlights. A reporting module compares measured deltas against common tolerance standards such as ΔE 2000, while an integrated curve viewer visualizes tone response and color temperature drift. Because DisplayCAL is released under a permissive license, the single-version lineage—currently at 3.9.17—remains fully open and portable, allowing color-critical workflows to be reproduced on any compatible system without licensing restrictions. DisplayCAL is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
