Convergence test pattern
Image 12-2
The test pattern illustrated above is specifically designed for convergence purposes. The test pattern has
three red arrows numbered from 1 to 3 and three green arrows numbered from 4 to 6. These numbers and
colors correspond to those of the control knobs. Turning the control knob clockwise corresponds to the
direction indicated on the screen.
Adjustment Range
Prevent damage to the system by limiting the amount/number of adjustment (s) made. Typically the
convergence adjustments serve to correct a convergence fault of a few pixels at the most. Any convergence
fault beyond this is considered grossly abnormal and likely indicates abuse or rough handling.
•
Each adjustment allows for approximately 20 pixels (for 4K projectors) maximum displacement to either
side of the nominal BLUE position.
•
Rotation is limited to approxi/- 10 pixels on the left screen flank and +/- 10 pixels on the right
screen flank.
•
One turn of a control knob relates to an approximately 10 pixels displacement on the screen.
CAUTION:
The system does have an end of travel in either direction, but using excessive force may
cause damage. Please handle gently.
Troubleshooting 'dead zone' of control knob
In rare cases it can happen that a control knob is loose in the perfect convergence position. This means 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. 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.
