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

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.
