QUBYX PerfectLum vs QuickGamma

QUBYX PerfectLum calibrates, verifies and runs quality assurance for medical displays, including DICOM GSDF calibration. It automates acceptance, constancy and routine QA tests with configurable pass/fail thresholds, scheduled daily, weekly, monthly or at custom intervals. Tests produce structured PDF reports with calibration and compliance results, luminance, contrast, ambient data and history. PerfectLum supports LUT calibration, ICC profile export and multi-monitor calibration for up to six displays. It works with QUBYX SmartSensor S1 and S2 and supported third-party measurement devices, and can connect to QUBYX RemoteQA for fleet monitoring, scheduled QA, failure tracking and centralized compliance reporting. Its workflows align with DICOM Part 14 GSDF, AAPM TG-18/TG-270, ACR, DIN 6868-157 and IEC 62563. QUBYX lists installers for Windows 10/11 x64 and macOS 12 or later on Intel and Apple processors. A free trial is available by email download link, with no duration stated. A workstation license costs $480 as a one-time purchase; a package with SmartSensor S2 costs $680, paid once.

QuickGamma is a Windows utility for adjusting monitor gamma without expensive calibration hardware. It can correct gamma to 2.2 and create an ICC profile with a VCGT tag containing data used to load a graphics card’s lookup table (LUT). QuickProfileLoader is installed automatically with the utility and can load a monitor’s LUT from that profile data. The listed capabilities also include LUT calibration, ICC profile export and multi-monitor calibration. Version 4.1.0.0 requires Windows 10 or higher; its installation file includes 32-bit and 64-bit versions, help files and no runtime libraries. QuickGamma is free for personal use, while commercial use requires written consent from the author. Private users may distribute the complete, unaltered installer, but not individual components. The author offers no express or implied warranties and invites donations. A SHA-512 checksum is published for checking downloaded file integrity. The maker also lists utilities for reading LUT and VCGT data and creating monitor ICC profiles.
