Section 3: Operation

From the factory, the projector can utilize any of the 3 pre-defined color performance settings identified at right (default=Max Drives), or colors can be driven on the basis of color temperature. For most applications, one of these gamuts will produce accurate and realistic colors from a variety of sources. They can be applied at

DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the pre- defined “Select Color Adjustment” options exactly suit your needs. For example, you may require a unique color gamut (range) for a single projector or application, or you may need to precisely match colors across multiple adjacent displays. In such cases, use the Color Adjustments by X,Y or Color Saturation submenu to define the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of colors produced in displays. You can create up to four custom color gamuts (User 1, 2, 3, or 4) with these adjustments.

Note that the two menus differ only in their user interface, so use whichever menu best suits your needs and application. A color meter can help with adjustments.

Color Adjustments by X,Y — Enter known x/y coordinates from the chromaticity graph.

Color Saturation — Adjust color slidebars and judge image color by eye or meter.

A user-defined color “adjustment” can be applied by selecting it in the Advanced

Image Settings menu (“Select Color Adjustment”).

COLOR ADJUSTMENT BY X,Y: Use

 

this submenu if you want to create,

 

alter or copy a color gamut (i.e.,

 

“color adjustment”). Controls in

 

this menu define the precise hue of

 

each primary color component (red,

 

green, blue, and white) used to

 

generate the millions of colors

 

produced in displays. The x/y

 

coordinates for each color define its

 

location on the standard CIE

 

chromaticity graph (see Figure

 

3.20)—changing either or both of

 

these numbers will change the hue

 

of the color, and relocate the

 

“triangle” for possible colors. For

 

example, changing the x/y

 

coordinates for red may move the

color closer to orange or closer to

 

 

violet, which will in turn affect all displayed colors having a red component. Adjust

 

the slidebars or enter new specific coordinates as desired to define or change up to
