Figure 3.16. Match Zones to Center Color Temperature
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

Step 3: Adjust Light Output in 8 Zones
For each screen, compare the light output of each edge and corner to that of the
3a)
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 3.17). 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.
