In their own words
pacsDisplay
pacsDisplay is an open-source project for calibrating DICOM grayscale displays and checking their image quality. Its calibration tools measure luminance response and create DICOM GSDF lookup tables. The iQC tool shows interactive quality-control patterns, including TG270-pQC, TG270-sQC, and TG270-ULN. For uniformity checks, uniLum collects luminance measurements and reports deviation from the median and mean luminance deviation. Other tools assess ambient lighting and measure luminance and illuminance. The listed compatible photometers include X-Rite i1Display Studio, Pro, and Plus; NEC SpectraSensor Pro; ColorMunki Display; Calibrite Display Pro and Plus HL; and rebranded meters. Version 6A supports external-display measurements in lumResponse and uniLum. The current release supports Windows 10 and 11. Its pdQC toolkit can be deployed from a USB drive or network without installation. The Windows installer places files in Program Files, the Public Users folder, and the Start Menu without modifying the registry or system services. Development began in 1999, and the project is distributed under the GNU General Public License v3.0.
QUBYX PerfectChroma
QUBYX PerfectChroma is display-calibration software for photographers, videographers, editors, and other color-critical professionals. It converts calibration measurements into ICC v4 profiles and 3D LUTs. Smart Calibration Presets target Rec.709, DCI-P3, and sRGB, while Precision Measurement records luminance, white point, and XYZ values. Delta E reports, calibration history, and PDF verification reports document results. LUT exports include.cube for DaVinci Resolve and.3dl for Autodesk Flame. The software works with most industry-standard colorimeters, including X-Rite and Calibrite devices, and supports multi-monitor and HDR calibration. It runs on 64-bit Windows 10 or newer and macOS 12 Monterey or newer. A 14-day trial requires no credit card. Paid licenses include the Pro License at $199 as a one-time purchase, Pro Bundle at $499, paid once, and Studio Bundle at $799, paid once.
