center.
NOTE:
Each corner is adjustable in either of its two adjacent "side" menus.

12. Adjust LIGHT OUTPUT
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
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

and darkest areas of the screen.
• Adjust corner White Uniformity last-each corner adjustment affects only this quadrant.
• Repeat for each screen.
