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 the optics can
reach a steady state.
2. In the right toolbar, select Test Patterns.
3. Select RGB-2K-Convergence 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.
6. Use the Convergence test pattern to assist with adjusting the horizontal and vertical lines.
Horizontal adjustments are controlled by adjusting knob 3.
Vertical convergence and rotation are controlled by adjusting knobs 1 and 2. Christie
recommends rotating a single knob a maximum of a quarter rotation before adjusting the
second knob a quarter rotation. For example, if using one hand, turn the left knob a quarter
rotation and then the right knob a quarter rotation, and so on. Adjusting a single knob for
vertical or rotational adjustment to an extreme before adjusting the second knob may result in
the convergence mechanism binding.
