ADJUST COLORS FIRST—
Matching Colors in Multiple Screens
This ensures that primary colors, color temperature, and maximized light output are all well matched from
one screen to another. These matches are needed before you can achieve good brightness uniformity
results.

RUN LAMP FOR 100 HOURS—
100 hours of lamp use. For best results with new lamps, either set up brightness uniformity after this
period, or do an initial setup and re-check at 100 hours.

SET LAMP POWER—
still maintaining a good overall match of light output from screen-to-screen. By nature, achieving a uni-
form 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 pro-
jector.
NOTE:
Power mode, use the Manual Dynamic Iris Position slidebar to adjust brightness. In Constant Intensity
mode, use the Intensity slidebar to adjust brightness.

USE 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 SLIDE BARS—
bar 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 slide bar to stop earlier than
expected.

b. Enable the Brightness Uniformity check box. This will enable access to the uniformity controls and
will apply the settings to your image.
c. Select the 13-Point test pattern for display. This pattern
provides nine screen "zones" with 13 targets, see
Pattern.
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.
d. In either Color Adjustments menu, select a "User" color. Then:
• If you have created a "User 1" color gamut (recommended)
for a well-matched wall, continue to Step 1e.
• If you prefer maximum brightness rather than a particular
color temperature, select Max Drives.
IMPORTANT! Do not change User 1 Color Adjustment in color-
