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.
