4-3
4-2-4 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 Tables 4-2 and
4-3, an image appears distorted, elongated or
squashed.
Table 4-1. Standard Modes Linearity: 640x480/85Hz,
800x600/85Hz and 1024x768/85Hz
Table 4-2. Other Modes Linearity: VGA, SVGA, XGA,
MAC, etc.
4-2-4 (a) HORIZONTAL LINEARITY ADJUSTMENT

To adjust the Horizontal Linearity, refer to Tables
4-2 and 4-3 for the tolerance range.
Increase or decrease H_LIN to optimize the
image.
4-2-4 (b) VERTICAL LINEARITY ADJUSTMENT
CONDITIONS
Scanning frequency:
68 kHz/85 Hz
Display image:

Contrast:
Maximum
To adjust the Vertical Linearity, refer to Tables 4-2
and 4-3 for the tolerance range.
Use control bar after selecting “V-LINEARITY
BAL”
in left menu to optimize the image.
