Section 6-3 - Monitor Adjustments 6-3
6-3-2 Brightness and Contrast
Adjusting the monitor's contrast and brightness is one of the most important factors for proper image
quality. If these controls are set incorrectly, the Gain, TGC, Dynamic Range and even Power Output
may have to be changed more often than necessary to compensate.
The proper setup displays a complete gray scale. The lowest level of black should just disappear into
the background and the highest white should be bright, but not saturated.
To adjust the contrast:
1.) Press the Toggle button on the display monitor once.
2.) Press the Adjustment (+) button to increase contrast. Press the Adjustment (-) button to decrease
contrast.
3.) The amount of contrast is shown on a slide bar on the screen.
To adjust the brightness:
4.) Press the Toggle button on the display monitor twice.
5.) Press the Adjustment (+) button to increase brightness. Press the Adjustment (-) button to decrease
brightness.
6.) The amount of brightness is shown on a slide bar on the screen.
Record any changes to the final brightness and contrast settings and leave this information with the
system. Generally speaking, do not change the controls once they have been set. Once set, the display
then becomes the reference for the hard copy device(s).
NOTE: After readjusting the monitor's Contrast and Brightness, readjust all preset and peripheral
settings.
