Figure 3.34. 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

Steps

2a & 2b for all remaining screens.

Step 3: Adjust Light Output in 8 Zones

3a) 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 3.35). 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.

Step 4: Readjust Color Temperature (level of red/green/blue) in 8 Zones

4a) Return to Steps 2a & 2b and, if necessary, fine-tune the zones so that they all

still exhibit a single color temperature.
