Start auto image

Auto imaging allows you to "auto size" and "auto center" the selected image to
fill the screen. The processor measures the sync frequencies of an incoming video
source and uses an internal table to set the active image area, total image area, and
the sampling frequency.
If an unknown input is connected to the DVS 304, the processor measures and
estimates the resolution of the incoming video.
To turn on this feature, select the Advanced Config menu and choose "On".
Start auto imaging on a selected input by pressing "Next" after the Start Auto
Image menu.
