Saturation.
Use the slider to adjust monitor window saturation. The value ranges from 0 to 100. The
default value is 50. The greater the number, the greater the color intensity. This value has no effect
on the general brightness of the video as a whole. For the gray part of the video, distortion may occur
if the white balance is not accurate. The recommended value ranges from 40 to 60.
Gain.
Move the slider to set the gain value. Generally speaking, the smaller the value, the lower the
noise—although the contrast may be too low in dark environments. A higher setting can enhance the
video brightness, though this may increase video noise.
Color Mode.
Move the slider to set several modes such as standard, color, bright and gentle. Then
when you select a color mode, the sharpness, brightness and contrast automatically switch to the
corresponding setups.
