In either Color Adjustments menu, select a "User" color. Then:
1d)
•
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
1e)
menu, set the "Overall"
output level to 50.0 and all
remaining slide bars 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 Eight 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 eight target zones (four
2a)
edges and four 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 3.16.

in color-matched applications!
