8.0 ADJUSTING THE IMAGE
70 R599791 - FORCE 3D User Manual
Advanced Image Settings menu (“Select Color Adjustment”), and are not adjustable.
DEFINING “USER” COLOR GAMUTS You may find the pre-defined “Select Color Adjustment” options do not 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: 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.
Use this submenu 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 3-38 CIE 1931 Chromaticity Diagram (without Yellow Notch Filter). 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 slide bars or enter new specific coordinates as
desired to define or change up to four “User” color gamuts needed for your environment and applications. Apply at
any time in the Advanced Image Settings menu.

NOTE: Keep new x,y coordinates within the original color gamut triangle shown here.
Color Saturation - Submenu
Adjust color slide bars 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’). Use this submenu if you do not have
specific color coordinates in mind and will judge color performance by eye or meter. Like the Color Adjustment by
X,Y submenu, each color control actually defines new x/y coordinates for that color and changes its hue. Adjust the
hue of each primary color (red, green, blue, and white) by using more or less of it in relation to the other colors.
NOTE: A Color Saturation adjustment defines the corresponding x/y coordinates shown in the Color Adjustment by
X,Y submenu. These x/y coordinates will remain stable for this User gamut until they are changed again via either
menu. Values displayed in the Color Saturation menu, will fluctuate as you use the projector, and will be different
when you return to this menu in the future. These floating changes do not affect the x/y coordinates or gamut.

gamut for this projector.
