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.
