9. 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.

10. 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.
11. When done, all areas of a given screen should match. Repeat Steps 2a and 2b for all remaining screens.
12. Adjust LIGHT OUTPUT in 8 Zones.
a. 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 Figure 3-36 ). Begin with the screen exhibiting the most 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.
