Section 3: Operation
IMPORTANT: Before You Begin
NOTE: Brightness uniformity cannot be adjusted for images that have been warped using Main
Menu>Configuration>Geometry and Color>Geometry Correction.
Read through the entire procedure before attempting to adjust Brightness Uniformity controls, and keep in
mind the following checklist of prerequisites and guidelines:
Adjust Brightness Uniformity
1. Before attempting to work with Brightness Uniformity, ensure that primary colors, color temperature, and
brightness output are all well matched from one screen to another. These matches are needed before you
can achieve good brightness uniformity results. See
IMPORTANT: Double-check that all WHITES and LIGHT OUTPUT are well-matched.
2. Enable the Brightness Uniformity check box. This will enable access to the uniformity controls and will
apply the settings to your image.
3. Select the 13-Point test pattern for Full White for display. The 13-
Point test pattern provides nine screen "zones" with 13 targets, see
Figure 3-12.
4. Determine by eye or meter which areas need to be adjusted.
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.
5. Enable Coarse Adjustment to quickly apply display changes
without redrawing the whole image.
6. Use sliders to achieve relative uniformity in the necessary zone.
7. Disable Coarse Adjustment to accurately display changes as you
make them.
8. Use sliders for fine adjustment as necessary in the required zones.
9. Adjust Overall Gain to ensure that overall light output remains well matched from one screen center to the
next.
