Section 4: Advanced Configuration and Controls
Before You Begin
Read through the entire procedure before attempting to adjust Brightness Uniformity controls, and keep in
mind the following list of prerequisites and guidelines:
•
ADJUST COLORS FIRST—
Screens before working with Brightness Uniformity. This makes sure that primary colors, color temperature,
and maximized light output are all 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—
maintaining a good overall match of light output from screen-to-screen. Achieving a uniform brightness will
require a slightly reduced overall brightness—this reduction will make sure that there is enough range of
adjustment when examining brightness variables from screen-to-screen.It will help prevent "maxing out"
before matching to a specific color, zone or projector.
•
USE A "USER" COLOR TEMPERATURE—
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—
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.
•
JUDGE BY EYE OR USE A METER—
Step 1: General Setup
a. Adjust primary colors (see Matching Colors in Multiple Screens) to make sure matched overall color
temperatures and light output between screens.
IMPORTANT:
b. Enable the Brightness Uniformity checkbox. This will enable access to the uniformity controls and will
apply the settings to your image.
White Boost is automatically disabled (grayed out in menu) when you enable Brightness Uniformity.

Verify that all WHITES and LIGHT OUTPUT are well-matched.
