Evaluating the image convergence
Evaluate the image convergence to discover if any adjustments are required.
1. Display either the Alignment or the Framing test pattern.
The framing test pattern may not be installed on the projector in some cases. Keep a copy of
this pattern on your computer and load it to the projector you are working on if not present.
2. Zoom and focus the image to see the entire outer edge of the test pattern frame.
3. Using the horizontal and vertical white lines, judge the convergence issues.
Look at one color at a time and remember that you can see a possible seven colors to lead
you to a valid conclusion. To help, use the stripe pattern boxes along the outer frames.
