Color Adjustment Procedure
Once the Color Primary Settings are calibrated for the site (see above), use the Color
Adjustments by X,Y menu to further refine each projector's fundamental primary
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 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 defining a new color palette, but do set up 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:
Start Select Color Adjustment to "Max Drives"
Display a full white test pattern
Adjust lamp power until 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 3.35. Or use
"Copy From" to copy these into a "User" gamut for this projector.
Figure 3.35. Jot Down a Set of "Max Drives" X/Y Values
(NOTE: MAGENTA, CYAN AND YELLOW ARE NO LONGER USED
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 3.36).
