Convergence test pattern
The test pattern illustrated above is specially 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 with the numbers and colors of
the extended control knobs (image 12-1). The direction of the arrow shows the movement of the channel color (red or green) when
turning the corresponding knob in the direction indicated by the arrow marked on the knob.
The three convergence control knobs of one channel stand in relation with each other. So, a change to one
of them will also effect the adjustment results of the two others. Therefore, all three control knobs have to
be alternately and repeatedly adjusted until the projected color is perfectly converged with the blue reference
color of the test pattern.
Adjustment range
•
The adjustment range is limited to approximately 30 pixels in both directions.
•
One turn (360°) of a control knob relates to an approximately 30 pixel displacement on the screen.
•
When changing the adjustment direction there will be some play of approximately one turn (360°).
