DisplayCAL vs QUBYX OS Tools

DisplayCAL is a free display calibration and profiling solution built on ArgyllCMS, available for Linux, macOS, and Windows. With a supported measurement instrument, it measures displays and creates calibrations and ICC profiles, including for multi-display setups. Users can verify profiles and display devices, measure screen uniformity, and create video 3D LUTs with optional CIECAM02 gamut mapping. Colorimeter corrections can be imported from vendor software or created from measurements when a spectrometer is available. A test chart editor makes patch charts and accepts pasted data from CGATS, tab-delimited CSV, and spreadsheet applications. Documented pattern generators include madVR and DaVinci Resolve 10.1 or later; Chromecast support is optional. DisplayCAL requires ArgyllCMS 1.0 or newer and a supported measurement instrument. The software is licensed under GNU GPL version 3 or later and comes without warranty. The download page provides SHA-256 checksums, while the site links to forums, a wiki, documentation, help, and an issue tracker.

QUBYX OS Tools is an open-source framework for software-based display color calibration and profile generation. It generates Device Link ICC profiles with embedded 3D LUTs, combining source-to-destination color conversions in one file. The software runs on Windows, macOS, and Linux and is described as being under the GNU License; users can inspect, audit, and adapt its code. Listed exports include .cube for DaVinci Resolve, Adobe Premiere, and Final Cut, plus .3dl, .icc, .lut, and Device Link profiles. Its stated audiences include medical software makers seeking DICOM-compliant accuracy across displays, as well as broadcast and television, photo and video studios, defense, marine and aerospace, color science and engineering, and digital press operators. QUBYX offers commercial support, certification, and custom development separately. The software is free, with no license fees or subscriptions. GPU-accelerated profile generation, GUI-based editors, and expanded support for newer display technologies are listed as coming soon.
