How ColorEdge Monitors Achieve Industry-Leading Precision

EIZO’s ColorEdge monitors with built-in calibration sensors are developed and manufactured entirely in-house. See how they achieve the colour precision and consistent image display needed for creative fields.

ColorEdge is a line of colour management monitors developed specifically for addressing users in photography, film, broadcasting, printing, and other creative fields. For these industries, not only colour fidelity, but display characteristics such as brightness, gamma, and uniformity across the screen need to be maintained so the final output content displays as intended in the target environment.

Rigorous Colour Adjustment at the Factory

Precision Calibration According to Industry-Standard Spectrophotometer

Calibration is a method by which a monitor’s display characteristics are adjusted to a target value using a dedicated sensor, or colourimeter. While the quality of the monitor and its display characteristics are integral to ensuring colour precision, consideration must also be made for the quality of the sensor used to calibrate the monitor prior to deployment to user environments. “Precision” means that the monitor and the sensor meet specific international standards set forth by the industry to achieve consistent results.

Each ColorEdge monitor undergoes rigorous quality control during production and is individually adjusted in-house using one of the colour industry’s highest end, professional spectrophotometers. The human perception of colour varies greatly depending on several factors such as ambient lighting, surrounding colour, angle of observation, and individual optical variances. Using a high-quality sensor to adjust the monitors to meet certain colour standards ensures consistency by minimising the effect these variables have in the measurement results. EIZO’s factory uses sophisticated machinery in its production line to automatically carry out calibration for each monitor in a controlled environment. The sensor is placed directly over the monitor and red (R), green (G), and blue (B) gamma values are measured from 0 – 255. Then the monitor’s 16- or 24-bit LUT (look-up-table) is used to select the 256 most appropriate tones from trillions of perceivable colours to achieve the smoothest colour gradations. This results in an image without deviated steps.

Careful Measurement of Multiple Points Across the Screen

LCD monitors commonly exhibit fluctuations in brightness and chromaticity across the screen, which affects colour precision. To counter this, EIZO also measures and adjust multiple points on each monitor to achieve stable brightness and chromaticity across the entire screen and correct deviations using its patented digital uniformity equalizer (DUE) technology. DUE controls the tone values pixel-by-pixel across the monitor for evenly distributed luminance.
