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
any time in the Advanced Image Settings
menu (“Select Color Adjustment”), and are
not adjustable.
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
