12. Convergence (with extenders)
12.1 Convergence controls
Extended control knobs
As the DMD of the blue channel is not accessible in the projector, the image of this DMD will be taken as reference. Red and green
will be aligned on blue when a small convergence drift is recognized. So, the DMD of the blue channel is fixed and can not be
adjusted. The red and green channel are equipped with three extended control knobs for convergence adjustment. The adjustment
knobs are numbered from 1 to 6 and have the same color as the channel which they effect.
