Adjustments Geometry - 16
If the horizontal controls seem stuck, move the controls
in one direction a large extent and if no affect is seen,
move them in the other direction a large extent until a
change is detected. Moving back and forth in small
increments will have no affect until the controls are
moved into the active range.
3 Click OK to save your convergence changes and close the
Convergence Control window.
Note:
If focus is poor after adjusting convergence, refer to
the Focus symptom in the Troubleshooting chapter.
