DisplayCAL vs HCFR: Display vs Projector Calibration
DisplayCAL and HCFR are both free, open-source calibration tools — and both need a colorimeter to do their job. The difference is the screen in front of you: DisplayCAL is built around computer monitors and color-managed workflows, while HCFR is built around TVs and projectors in home theaters.
What each tool actually does
- DisplayCAL measures your monitor, builds ICC profiles and 3D LUTs, and verifies the result with a detailed report. Its natural home is photography, design, and desktop video.
- HCFR works with a colorimeter and test patterns to help you adjust a TV or projector itself — grayscale, gamma, and color management controls. Its natural home is the living room.
Side-by-side comparison
| Feature | DisplayCAL | HCFR |
|---|---|---|
| Primary target | Computer monitors | TVs and projectors |
| Output | ICC profile / 3D LUT installed in the OS | Adjustments made on the display (grayscale, gamma, CMS) |
| Price | Free | Free |
| License | Open source (GPLv3) | Open source |
| Platforms | Windows, macOS, Linux | Windows |
| Test patterns | Built-in patch generator | External pattern sources / discs |
| Best for | Photographers, designers, color-managed workflows | Home-theater enthusiasts |
They complement each other
Nothing stops you from using both. A common setup: calibrate your photo-editing monitor with DisplayCAL for accurate ICC profiles, then dial in your living-room projector with HCFR’s display-side controls. They solve different problems, so owning both is normal, not redundant.
Honest weaknesses on both sides
- DisplayCAL: steep learning curve, dated interface, and no official support channel — you rely on community documentation.
- HCFR: Windows-only, focused on display-side adjustments rather than ICC profiling, and equally enthusiast-oriented — it is not a one-click tool either.

Frequently asked questions
Is HCFR really free?
Yes. HCFR is free, open-source calibration software aimed at TVs and projectors. Like DisplayCAL, it still requires a colorimeter — the software is free, the measurement hardware is not.
Can HCFR calibrate a computer monitor?
Not really — HCFR is designed around TVs and projectors and display-side adjustments. For ICC-based monitor profiling on a computer, DisplayCAL is the right tool.
Can DisplayCAL calibrate a projector?
DisplayCAL can profile any display that a supported instrument can measure, projectors included. But its workflow is built around ICC profiles and 3D LUTs for computers, while HCFR’s workflow is more projector-oriented.
Do I need a colorimeter for both?
Yes. Neither DisplayCAL nor HCFR can calibrate by eye — both need a measurement instrument such as a colorimeter to read what your screen is actually showing.
