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.
