4-2-1 Centering
Centering means to position the center point of
the display in the middle of the display area.
Horizontal size and position and vertical size and
position control the centering of the display.
Adjust the horizontal size and vertical size to their
optimal settings: 395 mm (H) x 296 mm (V).
1280 x 1024 mode (91 kHz/ 85Hz)
Adjust the horizontal position and vertical
position to
4.0 mm of the center point of the
screen.

4-2-2 Linearity
Linearity affects the symmetry of images as they
appear on the screen. Unless each row or column
of blocks in a crosshatch pattern is of equal size,
or within the tolerances shown in Table 4-1, an
image appears distorted, elongated or squashed.
Horizontal Linearity = 2x x100
Vertical Linearity = 2x x100
