Convergence Test pattern
For the manual correction of the DMD convergence, a typical convergence test pattern is generated. For a 4K
projector, use the 4K test pattern.

Work Instructions:
•
GREEN and RED DMD
’
s are to be adjusted with reference to the BLUE dmd.
•
Each adjustment allows for approximately 10 pixels (for 2K projectors) or 20 pixels (for 4K projectors)
maximum displacement to either side of the nominal BLUE position
•
Rotation is limited to approxi/- 5pixels on the left screen flank and +/- 5 pixels on the right screen
flank
•
One turn of an adjustment screw relates to an approx. 5-pixel displacement on the screen.
•
Let the projector warming up for 30 minutes, while projecting the convergence test pattern, before starting
to adjust the convergence.
Take Care:
•
In rare cases it can happen that the nominal dmd position falls within a
dead zone
, where the mechanism
changes from a pushing to a pulling function. This dead zone is due to inherent tolerances within the
mechanism. Approximately 2 turns are required to get out of the dead zone. If it so happens that the
nominal position of an adjustment falls within this dead zone, it is preferable to continue screwing through
the dead zone for another 2 turns. Then return to the required nominal position. The dead zone should now
be displaced away from the required end position. The DMD is now securely held in the nominal position.
•
Each adjustment is limited to approximately 10 pixels (for 2K projectors) or 20 pixels (for 4K projectors)
displacement. DO NOT try to force the adjustment beyond this point. The system has an end of travel in
both directions, but with excessive force one could cause damage.
