EDID EDID is a piece of data that HDMI receivers use to indicate their capabilities to the
HDMI sources.
The DM-MD8X8 routes Digital Media (DM) signals from any of the eight video
input cards to one or more of the eight 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-MD8X8 can be configured to use several different
algorithms to determine what EDID information is sent to each source:
• Copy Display
Copy Display
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.
