In either Color Adjustments menu, select a "User" color. Then:

If you have created a "User 1" color gamut (recommended) for a well-
matched wall, continue to Step 1e.

If you prefer maximum brightness rather than a particular color temperature,
select "Max Drives".
Do not change User 1 Color Adjustment
In the White Uniformity menu,
1d)
set the "Overall" output level to
50.0 and all remaining
slidebars to 0.0. This decreases
the light output just enough
throughout the screen so that
any color level can then be
increased later as necessary for
matching light output from
zone-to-zone. Do not exceed
50.0 for "Overall"—a higher
level will likely interfere with achieving brightness uniformity and is not
recommended.
Ensure that overall light output remains well-matched from one screen center to
the next. Where necessary, increase or decrease Lamp Power slightly to recover
center matches.
Step 2: Adjust Color (level of red/green/blue) in 8 Zones
NOTES: 1) At this point, ignore the brightness of individual zones. 2) Always
ignore menu colors.
On each screen, compare the color temperatures in the 8 target zones (4 edges
2a)
and 4 corners) to that of the color temperature of the center. Compare using a
white field only, and take note of any areas that do not match the center. Also
decide if any screen exhibits a more obvious color shift than other screens—
begin with this screen in Step
Return to the Brightness Uniformity menu. Beginning with the screen that exhibits
2b)
the most obvious color shift(s), for each edge that exhibits a noticeably different
color temperature from the center, select the corresponding Uniformity adjustment
menu—Left, Right, Top or Bottom. For example, if any part of the left side is too
blue, too red or too green, go to the Left Uniformity menu and adjust the colors (i.e.,
change their light output) until all portions of the left side closely match the center
color temperature. Adjust an edge first (focusing on its center), and then adjust its
corners. See Figure 3.31.
IMPORTANT
in color-matched applications!
