2.4 Monitor Adjustment

The monitor control panel on the right side of the monitor allows the
characteristics of the monitor to be adjusted.

The nineteen-inch monitors (60 Hz and 33 Hz) have two knobs labeled

Brightness

and

Contrast

, and a button labeled

Degauss

(see Figures 2-7 and

2-9).

The fifteen-inch monitor has two recessed dials labeled

Brightness

and

Contrast

, and a button labeled

Degauss

(see Figure 2-8).

NOTE: Color rendering and stability may drift for the
first 45 minutes after powerup.

1. After the monitor has warmed up, turn the

Brightness

and Contrast

controls to the maximum (clockwise) setting.

2. Turn the

Brightness

control down until the gray raster just
disappears in relation to the black area at the edge of the screen.
Lighter brightness settings impair image sharpness and color
fidelity.

3. After the

Brightness

control has been set, adjustment of the

Contrast

control is a matter of personal taste.

4. If the color purity or convergence appear to be out of adjustment,
hold down the

Degauss

button on the monitor control panel for
about five seconds and then release it. The image should improve
noticeably.

Once the nineteen-inch 60 Hz monitor has been adjusted, the

Brightness

and

Contrast

knobs can be pushed in: so that they are

flush with the surface of the monitor.
