Section 3: Operation

‰ADJUST COLORS FIRST—Always adjust the primary colors as described in the “Matching Colors in Multiple Screens” procedure (above) before attempting to work with Brightness Uniformity. 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—Light output and Brightness Uniformity can vary significantly during the first 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—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 SLIDEBARS—White Uniformity slidebar values may not 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.

‰JUDGE BY EYE OR USE A METER—Good brightness uniformity can be achieved with either.

Step 1: General Setup

1a) Adjust primary colors (see Matching Colors in Multiple Screens) to ensure matched overall color temperatures and light output between screens.

IMPORTANT: Double-check that all WHITES and LIGHT OUTPUT are well-matched.

1b) Enable the Brightness Uniformity checkbox. This will enable access to the uniformity controls and will apply the settings to your image.
