Auto Image menu

The Auto Image menu causes the MGP 464 to perform an automatic image adjustment in the selected window. Auto Image measures where the active area starts and stops, and adjusts input sampling accordingly, so that the image fills the window.

When an input is connected, the processor measures the sync frequencies of

the incoming video source and sets the active image area, total image area, and sampling frequency according to a table stored on the MGP. If an unknown input is connected to the MGP, the processor measures and estimates the resolution of the incoming video. If the processor’s estimate proves inaccurate, the Auto Image function makes measurements to more accurately set up the input sampling.
