repeating 3.4.1 to 3.4.4.
1st step
Adjust so that the vertical and horizontal lines forming a cross at
the center of the screen become straight. Check also the screen
size and the linearity of the horizontal and vertical lines.

Make the adjustment for the green in each screen mode, and use
the green as the standard screen for the red and the blue. To
change screen modes, use the SCREEN mode key.
Note:
Some coordinates for adjustment points are located outside
the screen. Be sure not to make adjustments on those
points, because adjustment of those coordinates will have
little effect on the screen.

Adjustment Technique
• See "3.3 Coarse adjustment of the green."
Adjust GH STATIC, SKEW and SIZE, and GV STATIC,
SKEW, PIN and SIZE to correct the screen location, tilt, screen
information volume, and peripheral pin distortion.
• See "3.4 Fine-adjustment of the green."
Fine-adjust the linearity of the vertical and horizontal lines
forming a cross at the center of the screen.
Note: In principle, only the selected point is changed in
MANUAL CONVER. mode. However, as the adjusted
data (amount of adjustment) increase, peripheral points
may be affected. So be sure not to greatly change the
adjustment data of one point, but change peripheral points
at the same time. See the examples below.
Peripheral points may
be affected.
If an adjustment point is
greatly moved to the right,
