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 Acoustic 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 brightness and contrast:
1. Press the monitor’s toggle button (2) for brightness and
contrast. Confirm that the brightness (or contrast) is
displayed on the monitor. If the contrast is displayed,
press the toggle button again.
