Why adjusting the input balance ?

The input balance is normally correct adjusted in the factory. But due to signal distribution or signal transmission, a color imbalance can be the result. This imbalance can be adjusted source by source for color critical applications. These adjustments influence only the actual custom adjustment file. This procedure is not so easy.

Attention : Before starting the Input Balance function, generate a signal with dominant black and white areas.
