Color Adjustment Procedure
Once the Color Primary Settings are calibrated for the site (see above), use the Color
Adjustments by X,Y or Color Saturation menu to further refine each projector’s
fundamental colors so that the hue and intensity of each color appears the same from
one display to another. Once matched, you will have created a single new shared
range of colors or “color gamut” that all of your projectors can produce. This
palette—named User 1, 2, 3 or 4—can be applied or disabled for a source at any time
throughout a bank of adjacent displays, simplifying both the setup and maintenance of
a “seamless” wall.
1. Set up and optimize all projector settings. You can ignore color temperature, since
you will be redefining color performance in this procedure, but do optimize each
projector in every other aspect. Closely align all screen edges.
2. Assign projector numbers to make communications easier. Use a wired keypad.
3. Use the same lamp mode for all projectors, and do the following:
Set Select Color Adjustment to “Max Drives”
Display a full white test pattern
Adjust lamp power and Optical Aperture until adjacent white fields appear the
same brightness.
4. Display the Color Adjustments by X,Y menus for all projectors. Each menu shows
the x/y coordinates defining the “Max Drives” color gamut for this projector. Jot
down the values shown in one (any) of the displays. See Figure 3.31. Or use the
“Copy From” function to copy them into a “User” gamut in one projector.

5. In each projector, select a “User” color adjustment (1-4) to enable Color
Adjustments by X,Y changes. Then enter your recorded x/y values into each menu
(Figure 3.32).
