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.
7. Adjust Color (level of red/green/blue) in 8 Zones
NOTE:
At this point, ignore menu colors and the brightness of individual zones.
8. 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 2b.
