5. In the White Uniformity menu, 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 1 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
NOTE: At this point, ignore menu colors and the brightness of individual zones.
1. On each screen, compare the color temperatures in the 8 target zones (4 edges 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 2.
2. 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, adjust the colors in the Left Uniformity menu (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
3. Repeat the color adjustment of sides and corners for each edge of the screen that does not yet match the
center.
NOTE: Each corner is adjustable in either of its two adjacent "side" menus.
4. When done, all areas of a given screen should match. Repeat Steps 2a and 2b for all remaining screens.
