DisplayCAL is a graphical user interface developed by Florian Höch for the display calibration and profiling tools of Argyll CMS, an open source color management system developed by Graeme Gill.

Calibrate and characterize your display devices using one of the many supported hardware sensors, with support for multi-display setups and a variety of available settings like customizable whitepoint, luminance, tone response curve as well as the option to create matrix and look-up-table ICC profiles, with optional gamut mapping, as well as some proprietary 3D LUT formats.

Features:

• Support of colorimeter correction for different screens via correction matrices or calibration specral sample files (the latter only for specific colorimeters: i1 Display Pro, ColorMunki Display and Spyder 4/5).
• Profile verification and measurement report: check the quality of profiles and 3D LUTs via measurements. Also supports custom CGATS files (e.g., FOGRA, GRACoL/IDEAlliance, SWOP) and using of reference profiles to obtain test values.
• Test chart editor: Create charts with any amount of color patches, easy copy-and-paste from CGATS, CSV files (only tab-delimited) and spreadsheet applications.
• Create synthetic ICC (matrix) profiles with custom primaries, white-, and blackpoint, as well as tone response.
