Introduction

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.

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. 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.
