Image Adjustments

Image adjustments apply to scaled video output only; RGB signals are passed through without adjustments. Sizing and centering image adjustments can be stored in memory as a preset (see the “Memory Preset” section in this chapter) and can be set separately for each input.

Color, tint, brightness, contrast, centering, blanking

To adjust an image for color, tint, brightness, contrast, centering, or blanking, follow the steps below. An example of making color adjustments, shown in the flowchart below, demonstrates the process, which is similar for all the other image adjustments.
