Factory Adjustment of Gamma

Not only are the ColorEdge models designed for accurate color reproduction, but each unit is adjusted at the factory to a gamma value of 2.2. This is accomplished by measuring the R, G and B gamma values from 0-255, then using the monitor's 10-bit Look-Up Table (LUT) with its 1,021-tone palette to select the 256 most appropriate tones to achieve the 2.2 value. Users can also set their own values from 1.0 to 2.6 in 0.1 increments with the ColorNavigator 3 software. This is important because accurate, non-fluctuating gamma values are necessary for the proper display of color. If colors are not based on specific values and cannot be adjusted, images will be displayed differently by different monitors. ColorEdge monitors provide both precision and consistency, so graphics professionals can be sure that the final product will look exactly the way they want it to.
Accurate Color Temperature
Another important factor in achieving accurate, natural colors, especially for midtones, is setting the proper color temperature for white (white point). ColorEdge monitors are exceptionally versatile in this regard, providing color temperature adjustment from 4,000K to 10,000K in 500K increments (including 9,300K). This wide range ensures that users can achieve the optimum color temperature for any type of work, such as "paper white" for DTP.
ColorNavigator Calibration Software

This EIZO-developed software comes bundled with ColorEdge models and offers cross platform compatibility with Macintosh (9.2.2 and OS X 10.2 or later) and Windows (98SE, Me, 2000, and XP) operating systems. When used with the ColorEdge CX1 calibrator or a GretagMacbeth Eye-One color measurement device (sold separately), it offers hardware calibration of the monitor for more accurate control of color parameters.
SIMPLE AND PRECISE CALIBRATION
Most calibration software requires adjusting the monitor in accordance with an OSD menu. This is not only time consuming, but also depends on the user's perception of color, making accurate calibration results difficult to achieve. ColorNavigator is both simple and accurate - just set the target values for brightness, white point (color temperature or color coordinates) and gamma, then calibrate.

0.5ΔE DIFFERENCE
ColorNavigator offers hardware calibration of ColorEdge monitors. The primary benefit of hardware calibration is that the monitor itself is adjusted so gradations in an image are not sacrificed in the calibration process. Software calibration on the other hand, conducts color adjustment on the graphics board, resulting in a loss of displayable color gradations. By controlling the 10-bit Look-Up Table of ColorEdge monitors, ColorNavigator can adjust white point, color coordinates, and brightness without any reduction in gradations. When ColorNavigator is used with the ColorEdge CX1 calibrator or a calibrator from the GretagMacbeth Eye-One Series, the result is highly accurate colors with a ?E* rating of less than 0.5.

*ΔE: The color difference between the target white point and the monitor's white point.
COLOR PROFILE GENERATION
ColorNavigator can save up to 20 different calibration results. Any of these results can be used for setting the monitor or generating a ColorSync or ICM color profile for the computer's operating system. For example, if you use one monitor for both web design and printing, you can save a different calibration result for each task. When switching between tasks, just call up the appropriate result in ColorNavigator and the settings will immediately change.

Listing of Calibration Results
POST-CALIBRATION COLOR CORRECTION
Sometimes in the printing process, achieving satisfactory color matching with printed material or another target reference is still difficult even after calibrating the monitor and using the color profile. For additional color manipulation, ColorNavigator allows adjustment of red, green, blue, cyan, magenta, and yellow. The hue and saturation for all six colors can be adjusted independently.
COLOR COORDINATES AND BRIGHTNESS MEASUREMENT
ColorNavigator includes a brightness and chromaticity measuring function that can take a reading of the monitor's brightness and color coordinates. Up to 20 results can be saved for continuous, long-term tracking of the monitor's performance.

10-Bit Processing for Smoother Gradation of Color
This valuable feature assures the ColorEdge models (CG21, CG19, and CG18) produce smoother gradations of color than was possible before. It accomplishes this by automatically converting 8-bit data (256 gradations) received from the computer to 10-bit (1021 gradations) and then reassigning this data back to 8-bit with the ideal gamma values. For color-rich images, this means that even subtle mid-tones are displayed correctly.
14-Bit Processing
 |
The ColorEdge CG220 incorporates a powerful new EIZO-developed ASIC (Application Specific Integrated Circuit) with 14-bit color processing capability (16 times more accurate than 10-bit). This allows a larger number of grayscale increments, for grayscale rendering that is on a par with high-end CRT monitors. The result is a much greater degree of color detail, especially in dark areas and shadows. |
Auto Brightness Control
 |
This EIZO-patented circuit stabilizes brightness soon after startup or coming out of power save mode. Additionally, this circuit eliminates brightness fluctuation by detecting changes in the surrounding backlight temperatures and automatically adjusting the divergence to the brightness default setting or user-defined level. |
