Adjusting digital micromirror device
convergence
A digital micromirror device (DMD) 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 accredited service technician to correct DMD convergence issues.
