HCFR Colorimeter review
A capable free calibration toolkit for Windows users with supported colorimeters.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
HCFR Colorimeter is free, open-source Windows software for calibrating video projectors and monitors with supported colorimeters. It is aimed at advanced end users, desktop users, and science or research applications that need measurement-based control over grayscale, gamma, gamut, color-checker, or HDR-10 calibration. ArgyllCMS-based colorimeter access forms the measurement foundation, while video-card linear gamma LUT loading supports an additional calibration workflow.
Its strongest fit is home-theater and display work that requires flexible test-pattern options. HCFR supports internal, DVD, Chromecast, and external test-pattern workflows, along with madVR Test Pattern Generator support and Raspberry Pi integration. That range gives Windows users several ways to display patterns across projectors and monitors, rather than tying the workflow to one generator. Color-checker measurement patterns extend the software beyond basic grayscale and gamma adjustments, while HDR-10 support covers a wider range of display calibration tasks.
The product also supports practical documentation and export: calibration reports can be generated as PDFs, and measurement data can be exported to CSV/XLS or PDF. The trade-off is scope and platform choice. HCFR Colorimeter is limited to Windows, requires a supported colorimeter for its core measurement workflows, and does not verify ICC profile export. Users seeking a free, open-source Windows tool for detailed display and home-theater calibration should consider it; those needing another operating system or verified ICC profile export should choose an alternative.
