CRT Projection angle adjustment
The projection angle of the red and blue CRT's is dependent on the desired size of the projected image.
A new projection angle adjustment is required whenever a new screenwidth SW is adopted.
If the centers of green, blue and red do not coincide, the CRT projection angle must be adjusted.
Note
Never try to correct this misalignment with the shift correction or the static convergence controls.
These shift correction controls may only be applied to correct small errors which cannot be corrected by the CRT angle adjustment.
Note: The Horizontal Shift and Vertical Shift for Red and Blue should be set near 50%.
Be sure that the rasters are centered on the CRT faceplate.
