CRT projection angle adjustment
The projection angle of the red and blue CRT's is dependent on the desired size of
the projected image. If the centers of green, blue and red do not coincide, the CRT
projection angle must be adjusted. Never try to correct this misalignment with the shift
correction or the static convergence controls. These controls may only be applied
to correct small errors which cannot be corrected by the CRT angle adjustment.
Ensure that the rasters are centered on
the CRT face.
