Evaluating Convergence - Christie CP4220 Instruction Sheet

EVALUATING CONVERGENCE

1. Display either the Alignment Pattern or the Framing Pattern (Figure 4). NOTE: The framing
pattern may not be installed on the projector in some cases. Keep a copy of this pattern on your
laptop and load it to the projector you are working on if it is not present.
2. Zoom and focus the image so you can see the entire outer edge of the test pattern frame.
3. You should be able to judge the convergence issues by using the horizontal and vertical white
lines. Look at one color at a time and remember that you can see a possible 7 colors to lead you to
a valid conclusion. (Figure 5) The stripe pattern boxes along the outer frames can be very helpful
as well.
