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.

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.
NOTE: On DLV models, the Power control is fixed at 150W to maximize lamp life. In Constant
Power mode, use the Manual Dynamic Iris Position slide bar to adjust brightness. In Constant Inten-
sity mode, use the Intensity slide bar 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
adjusts overall light output in a specific screen zone, but the value shown represents the current set-
ting 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.

IMPORTANT! Double-check that all WHITES and LIGHT
OUTPUT are well-matched.
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 as shown.
NOTE: 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.
