It takes a standard video input and transforms it into a signal which makes a multi-sync display give its best possible performance. Supervisor is not a simple line-doubler. It works by either increasing the number of lines in the input image to make the scanning structure invisible, or increasing the image display rate to eliminate flicker, or a combination of both to achieve optimum output. It also enables SVGA images to be seamlessly mixed with video and displayed simultaneously. Item powers and functions correctly
