When a DVI video source boots up it normally communicates

with the output device using the bi-directional Extended

Display Identification Data (EDID) communication protocol.

The output device then produces a signal with a resolution that

is compatible with the output device.

Extron's EDID Minder feature maintains continuous EDID

(Extended Display Identification Data) communication with

the attached source and ensures that the DVI source powers

up correctly and maintains a proper video output, even if the

display is off or when a new monitor is connected to the output.

When the distribution amplifier is powered on, it automatically

scans all detectable outputs, selects the device with the lowest

native resolution and passes the EDID information of that

device to the input device.
If no output displays are connected, the distribution amplifier

provides the EDID information stored from the last display to

which it was connected. If no output device has previously been

connected to the unit, or the unit has been set to the factory

default, it uses the factory default resolution (1024 x 768).
