3.5.6 Blue Formatter Convergence Adjustment
The Blue Formatter differs greatly in physical layout and adjuster function compared to the Red/Green
Formatters. The biggest difference is that the horizontal and twist adjustments interact with each other because
the twist functions on the vertical axis in Blue, as opposed to the horizontal axis with the Red/Green Formatter
adjustments.
Figure 3-15 Blue Formatter Convergence Adjustment
The physical layout of the Blue Formatter
board also dictates the behavior of the twist adjustment:
• The horizontal adjustment screw and twist adjustment screw interact with each other such that if one is
turned in the opposite direction of the other, the twist is affected.
• If they are turned in opposite and equal amounts, the twist almost works as if it really was twisting: Pivoting
from the center of the image.
• If both screws are turned equal amounts in the same direction, the image moves horizontally.
• You do not always have to turn the screws simultaneously. Adjusting one at a time will cause the need for an
equal or equal and opposite turn on the other to prevent binding and achieve the adjustment desired.
