Section 3: Operation
• Set lamp power. Make sure each "Lamp Power" setting is as high as possible for 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. Always adjust Brightness Uniformity for 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 sliderbars. White Uniformity slidebar values may not always reduce to "0". Each slide-
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 reaches "0" first, causing the slidebar to stop earlier than expected.
• Judge by eye or use a meter. Good brightness uniformity can be achieved with either technique.
Step 1: General Setup
1. Adjust primary colors (refer to
overall color temperatures and light output between screens.
IMPORTANT
!
2. Enable the Uniformity Enable check box. This
enables access to the uniformity controls and applies
the settings to your image.
3. Select the 13 Point test pattern for display. This pattern
provides 9 screen "zones" with 13 targets.

4. In either Color Adjustment menu, select a color. Then:
• If you have created a "User 1" color gamut (recommended) for a
well-matched wall, select "User 1" and continue to Step 6.
• If you prefer maximum brightness rather than a particular color
temperature, select "Max Drives".
IMPORTANT! Do not change User 1 Color Adjustment in color-
matched applications!
