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.
Press ENTER to start the CRT angle
adjustment procedure. A crosshairs
