f. Make sure that overall light output remains well-matched from one screen center to the next. Where
necessary, increase or decrease Lamp Power to recover center matches.
Step 2: Adjust Color (level of red/green/blue) in 8 Zones
NOTES:
1) Ignore the brightness of individual zones.
2) Ignore menu colors.
a. 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
b. 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), then adjust its corners. See
Match Zones to Center Color
Repeat the color adjustment of sides and corners for each edge of the screen that does not yet match the center
(note that each corner is adjustable in either of its two adjacent "side" menus). When done, all areas of a given
screen will match. Repeat Steps
Step 3: Adjust Light Output in 8 Zones
c. For each screen, compare the light output of each edge and corner to that of the center. If any of the
areas differ, use the White Uniformity menu to match edges and corners to the center as described
below, see
obvious variations in light output.
• Adjust edge White Uniformity first—note that each edge adjustment also affects the rest of the
screen slightly. Keep all edges just slightly lower than the center light output rather than matching light
output precisely. Otherwise, it may not be possible to brighten the corners (typically the dimmest areas
of the screen) enough. I.e., the best uniformity is a compromise between the brightest and darkest areas
of the screen.
• Adjust corner White Uniformity last—each corner adjustment affects only this quadrant.
• Repeat for each screen.
