Start Auto Image
Auto image an input to "auto size" and "auto center" the image to fill the screen. The
processor measures the sync frequencies from incoming video sources 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 unit, the processor measures and estimates the
resolution of the incoming video.
The DVS 304 can be set to automatically auto-image newly detected inputs (see page 21).
