Figure 3.17. 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 Eight 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 3.18). 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 Eight
Zones
4a)
Return to Steps
2a
&
2b
and, if necessary, fine-tune the zones so that they all
still exhibit a single color temperature.
