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).

NOTE:
An input with a vertical refresh rate less than 40 Hz will have to be manually
centered and sized, using H/V Start and H/V Active under the Input Config
menu. When a rate with a low vertical refresh rate (for example 720p, 29.9 Hz)
is applied and an auto image command is issued, the DVS refers to default
values instead of performing a true auto image.

Input Configuration Menu
NOTE:
Only inputs 2 and 4 offer selectable video types. From the Input Configuration
menu, pressing the Next key successively displays submenus with the input
video types for Inputs 2 and 4. The SDI input (where applicable) can be assigned
to any input from the Input Configuration menu.
