convergence
A convergence problem occurs when one or more projected colors (red, green, blue) appears
misaligned when examined with a convergence test pattern.
Normally, the three colors should overlap precisely 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.
Contact your Christie qualified service technician to correct digital micromirror device (DMD)
convergence issues.
