Evaluating The Convergence Adjustments - Christie CP2208 Service Manual

adjustment functions are the same. The vertical and twist adjustments work together on the
horizontal axis.
The physical layout of the Formatter boards determines the behavior of the Twist and Vertical
adjustments:
• The vertical adjustment screw and twist adjustment screw interact with each other such that if
