Input Balance - Barco PFWX-51B User Manual

Video AGC
Video AGC refers to automatic gain correction function. When enabled, the AGC function applies gain corrections on the input
necessary to display correct output colors.
Video Saturation
Press or to adjust the saturation of the projected image.If the color of the projected image seems to be overly bright
and vivid, decrease the color saturation; if the color seems white and washed out, increase the color saturation.
Video Tint
Press or to adjust the tint (balance between magenta and green) of the projected image. Lowering the value will make
the image appear greener; increasing the value will make the image appear redder.
Input Configuration

range).

Unbalanced color signals
When transporting signals, there is always a risk of deterioration of the information contained in the signals.
In case of information contained in the amplitude of the signals which is the case of data color signals (R, G, B),image 9-29 ,
we are quite sure that the amplitude of these color signals is subject to alterations.
An example of alteration may be a DC component added to the signal, in the form of a DC offset repositioning the black level,
since this black level ("brightness") will become crucial later on (clamping circuit) it will result in "black not being black".
Another value that is subject to alteration is the amplitude of the signal, resulting in an altered "Gain" of the signal ("white
level" or contrast).
