Extron electronic DVS 304 manual Start Auto Image, Input Configuration

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.
