Section 6-2 - Monitor Adjustment 6 - 3
6-2-1-1 Brightness/Contrast
6-2-1-1-1 Brightness
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.
1.) Adjust the BRIGHTNESS by pressing the <
LEFT
or
RIGHT
> button to decrease/increase value.
6-2-1-1-2 Contrast
1.) Press the
MENU
(middle) key of the monitor controls over 10 sec.
2.) Select the Picture -> Contrast by pressing the < LEFT or RIGHT > button to decrease/ increase
cursor and the
MENU
(middle) key.
3.) Adjust the CONTRAST by pressing the < LEFT or RIGHT > button to decrease/increase the value.
(Default : 80)
NOTE: Brightness and Contrast should be adjusted at examination room light conditions.
