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.

1. From the Test Pattern menu, select the Convergence test pattern.

2. Open the Service door on the side of the projector.

3. To adjust the convergence knobs, use the 3 mm tool included with the projector.

If adjusting by hand without using the tool, pull out the convergence adjustment knobs to

engage them.

4. Use the Convergence test pattern to assist with adjusting the horizontal and vertical lines.

Vertical convergence and rotation is done by adjusting two knobs. 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.
