•
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”.
IMPORTANT:
Do not change User 1 Color Adjustment in color-matched
applications!
1e)
In the
White Uniformity
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.
2a)
On each screen, compare the color temperatures in the eight target zones (four
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
2b
.
2b)
Return to the
Brightness Uniformity
menu. Beginning with the screen that exhibits
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 3.17.
