EIZO ColorNavigator 7 vs PsyCalibrator

EIZO ColorNavigator 7 calibrates EIZO ColorEdge monitors and manages their quality control. EIZO positions it for creative work in photography, design, print, and video. Users can set multiple color modes from target values and the monitor’s on-screen menu, calibrate Standard Mode color modes together, and schedule recalibration even while the monitor is switched off. Calibration information is saved on the monitor, allowing users to move between PCs without recalibrating. Print-proofing targets support adjustments to hue and saturation across six primary and secondary colors, as well as grayscale balance. On supported CG Series monitors, the software can create film-emulation data from a video workflow’s 3D LUT; CG2730 and CG2420 are excluded. Built-in ColorEdge CG sensors can be correlated with high-end spectrophotometers. Its API allows third-party applications to change modes, create calibration targets, control SelfCalibration, and retrieve results; it requires version 7.1.12 or later. The free download is for compatible EIZO ColorEdge monitors. Supported systems are macOS 11–14, Windows 10 64-bit and Windows 11, and Red Hat Enterprise Linux 7 or 8 64-bit; ARM-based Windows is unsupported.

PsyCalibrator is a free, open-source package for measuring display luminance and color and calibrating gamma. It uses a Spyder5, SpyderX, or SpyderX2 instrument and returns measurements as CIE 1931 xyY coordinates. Its correction workflow adjusts the relationship between RGB intensity and luminance to be linear, for grayscale or individual color channels. The fitting process incorporates Mcalibrator2 and uses cubic spline interpolation as its main method. Users can apply correction through a color lookup table and restore the display to its uncorrected state. PsyCalibrator supports Windows, macOS, and Linux and includes multi-monitor calibration. Its research workflow requires MATLAB or GNU Octave, Psychtoolbox, and a supported Spyder instrument. The tutorial says Windows users need a photometer driver; Linux and Mac users do not. SpyderX and SpyderX2 can use built-in Windows 10 or 11 drivers with Psychtoolbox 3.0.19 or later. For more accurate measurements, the tutorial recommends keeping ambient light steady and using a sensor area smaller than the target stimulus.
