EDID
EDID is a piece of data that HDMI receivers use to indicate their capabilities to the
HDMI sources.
The DM switcher routes DigitalMedia (DM) signals from any of the input cards to
one or more of the output channels. According to the HDMI standard, HDMI sources
are expected to only deliver audio and video formats that are supported by the
destination. To do this, the DM switcher reads the EDID information from devices
connected to the outputs and determines the video resolutions and audio format to
send to the input cards to program EDID on the input card receivers.
Using Crestron Toolbox, the DM switcher can be configured to use several different
algorithms to determine what EDID information is sent to each source:

The EDID information from a DigitalMedia or HDMI output is copied to
the input verbatim. This means that all resolution, audio and vendor
information will be from that display.
