12. Convergence
12.1 Convergence controls
Extended control knobs
As the DMD of the red channel is not accessible in the projector, it remains fi xed. Therefor the image of this DMD will be taken as
reference. Blue and green may be aligned onto red when a small convergence drift is recognized. The blue and green channels
have pivot plates equipped with three control knobs for convergence adjustment, two of which are extended (reference 2, 3, 5 and
6 of image 12-1) . The adjustment knobs are numbered from 1 to 6 and have the same color as the channel which they affect.
To access the control knobs the top cover and left side cover of the projector and the top cover plate and side cover plate of the
Light Processor compartment have to be removed. For easy access to control knobs No1 and No4, we advise locating the Light
Processor top fan unit in it’s upper position, hereby still providing the necessary cooling to the unit.
