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.
For the best stability, Christie recommends setting convergence while rotating the knobs in a
clockwise direction. This may require first adjusting convergence by turning the knobs counter-
clockwise, and finalizing the convergence with a clockwise approach. This applies to all knobs.
7. When complete, push in all the convergence adjustment knobs to disengage them.
Electronically adjusting convergence with the remote
Use the electronic convergence feature with the remote to adjust convergence. It can be used in
addition to or instead of mechanical DMD convergence. When used in addition to mechanical DMD
convergence, Christie recommends completing mechanical convergence prior to making electronic
adjustments.
When using the remote to do electronic convergence, the following functionality is not available:
• Lens movement functions
• Image optimization and setting the aspect ratio
• Keystone adjustments
• Customized actions
• Context-sensitive help
• On-screen display menu
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. On the remote, press Test Pattern and select the E-Convergence test pattern.
The E-Convergence test pattern is displayed, including the instructional text. To remove clutter
from the screen or if you are familiar with the electronic convergence, turn off the instructional
text. On the remote, press OSD Hide for two seconds.
Until electronic convergence is completed, the displayed image may appear to be blurred and
difficult to read, especially for white text, due to the mis-convergence of the red, green, and
blue pixels.
