Adjusting Dmd Convergence - Christie CP2315-RGB Installation And Setup Manual

10. If further action is required, repeat steps 2 to 9.
11. Lock the setscrews, and re-check the boresight quality.
Tighten the setscrews to 2.1 Nm (18 in-lb) to ensure they do not shift.

Adjusting DMD convergence

A convergence problem occurs when one or more projected colors (red, green, and blue) appears
misaligned when examined with a convergence test pattern.
The three colors should overlap to form pure white lines throughout the image and one or more poorly
converged individual colors may appear adjacent to some or all of the lines.
When adjusting the convergence, you are adjusting red and green to blue.
If you wear glasses with corrective lenses when performing this adjustment, ensure that 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, ensure 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 that the
optics can reach a steady state.
2. In the right toolbar, tap Test Patterns.
3. Select the RGB-2K-Convergence test pattern and display it full screen.
4. Open the Service door on the side of the projector.
5. To adjust the convergence knobs, use the 3 mm driver included with the projector.
If adjusting by hand without using the tool, pull out the convergence adjustment knobs to
engage them.
