12.1 Convergence controls
Extended control knobs
As the DMD of the red channel is not accessible in the projector, it remains fixed. 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.
