7-4 Linearity
Linearity affects the symmetry of images
displaying 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
7-1 and 7-2 an image appears
distorted, elongated or squashed.
To adjust the linearity to its optimum setting,
apply one of the formulas below, or refer to the
table.
7-4-1 Conditions
Display image: Crosshatch pattern with 16 blocks
horizontally and 12 blocks vertically.
Maximum and minimum values should not be
adjacent to each other.
Table 7-1. Standard Mode Linearity: 37.5 kHz/75Hz,
46.875 kHz/75 Hz
