6-3-1 Brightness/Contrast (R1.x.x)
6-3-1-1 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 chaged 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) Go to Utility -> System -> General.
2) Press the OSD Control button to adjust the BRIGHTNESS and Contrast by using scroll bar to
decrease/increase value.
