ColourSpace vs QUBYX PerfectLum

ColourSpace is display calibration and colour management software for professional film, post-production, broadcast, medical, Pro AV, and home cinema work. It profiles display performance and uses those measurements to generate calibration LUTs. Interactive volumetric 3D graphs help assess measured colour points and their errors; higher license levels support native LUT generation at 1024³ and beyond. The maker lists integrations with displays and video systems including ASUS ProArt, EIZO, BenQ, LG TVs, AJA ColorBox, Lumagen Radiance, and madVR Envy. ColourSpace is a native Windows x64 application. The maker says Mac use is possible through full Windows emulation and describes a native macOS version as in development. ColourSpace ZRO is free for manual calibration and verification, but has no LUT capability, volumetric graphs, or calibration reports. Standard licenses cover one PC, require internet access for activation and periodic checks, and can be moved through up to five deactivation and activation cycles. Pricing is listed from £125.

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.
