Return to the Brightness Uniformity menu. Beginning with the screen that exhibits
E
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 Figure 3.43.
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 should match. Repeat

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.
