Start Auto Image - Extron electronics DVS 304 Series User Manual

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 Auto Memory
INPUT 1
COMPOSITE
Figure 11.
NOTE: An input with a vertical refresh rate less than 40 Hz will have to be manually
centered and sized, using
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.
