Description
Noise Reduction
This function reduces electrical image noise caused by different
media players. The higher the setting, the less the noise. (Not
available when input signal is HDMI.)
Color Management
Only in permanent installations with controlled lighting levels
such as boardrooms, lecture theaters, or home theaters,
should color management be considered. Color management
provides fine color control adjustment to allow for more
accurate color reproduction. Select Primary Color first and
adjust its range/values in Hue, Saturation and Gain.
Returns current image settings to the factory preset values.
