3.5.2 Evaluating Convergence
1. Display either the Alignment Pattern or the Framing Pattern. ( Figure 3-7 )
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. Using the horizontal and vertical white lines, you should be able to judge the convergence issues. 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 3-8 ) The stripe pattern boxes along the outer frames can be very helpful as well.
