Note procedure!

For most applications, the Display Color controls in the Calibration menu are adequate for producing accurate and realistic colors from a variety of sources.

In rare cases, though, you may need more precise control over the VX-2ix display color gamut (range). For example, you may require a unique color gamut for a given projector or application. In such cases, you can access the VX-2ix’s color gamut controls via serial commands. This enables you to define the precise hue of each primary color component (white, red, green and blue) used to generate the millions of colors produced in displays. You do this by specifying x and y coordinates for each primary color component.

The x and y coordinates for each color define its location on the standard CIE chromaticity graph, shown in Figure A-1.(CIE stands for “Commission Internationale de l’Éclairage” (International Commission on Illumination), the organization responsible for color measurement and management standards.)

Changing either or both of these numbers changes the hue of the color and relocates the “triangle” for possible colors. For example, changing the x/y coordinates for red moves the color closer to either orange or violet, which in turn affects all displayed colors having a red component.
