 SET LAMP POWER—
your application while still maintaining a good overall match of light output from
screen-to-screen. By nature, achieving a uniform brightness will require a slightly
reduced overall brightness—this reduction will help ensure that you have enough
range of adjustment when examining brightness variables more closely from
screen-to-screen, and will help prevent premature "maxing out" when trying to
match to a certain color, zone or projector.
 USE A "USER" COLOR TEMPERATURE—
a User color temperature defined when you matched primary colors, and
continue to use it for all sources displayed on the wall. Your other color
temperatures will not necessarily be matched from screen-to-screen.
 WHITE UNIFORMITY SLIDEBARS—
reduce to "0". Each slidebar adjusts overall light output in a specific screen zone,
but the value shown represents the current setting for green in this zone. When
other "hidden" values (red or blue) are lower than green, during adjustment in the
White Uniformity menu their values will reach "0" first, causing the slidebar to
stop earlier than expected.

Select the 13-Point test pattern for display.

This pattern provides nine screen "zones"
with 13 targets.
FOR BEST RESULTS: Rather than
examining the CENTER of each zone when
assessing Brightness Uniformity
adjustments focus on extreme EDGES as
indicated in the illustration at right.
In either Color Adjustments menu, select a "User" color. Then:
