1. If the image suffers from slight keystone effect, it can be corrected with electronic cropping.
2. If the keystone effect is severe, unevenly adjust the feet to compensate for projector tilt.
Christie recommends using the lens offset to align the center of the image to the center of the
screen before correcting the keystone effect.
3. If one side of the image is longer than another, adjust the tilt and level of the projector.
Adjusting DMD convergence
A convergence problem can be identified when one or more projected colors (red, green, and blue)
appears misaligned when examined with a convergence test pattern.
The physical layout of the green and blue formatter boards dictates the behavior of the twist and
vertical adjustments:
•
The adjustment of the two is more like a twist with the left-side of the screen as a sliding hinge
point to allow vertical travel.
•
The vertical adjustment screw and twist adjustment screw interact with each other so if one is
turned in the opposite direction of the other, the twist is affected.
•
If both screws are turned equal amounts in the same direction, the image moves vertically.
If you wear glasses with corrective lenses when performing this adjustment, make sure you are viewing
the test pattern on a straight angle through the optical axis of your glasses and not from a tilted or
angled perspective. This avoids a prismatic effect that can appear to shift convergence when viewing at
an angle.
1. Before adjusting DMD convergence, make sure the projector has reached a steady operational
state.
If switching from a white or bright test pattern to a dark convergence test pattern or if
warming up the projector after a shutdown, allow 15 minutes for stabilization so the optics can
reach a steady state.
2. In the right toolbar, select Test Patterns.
