EDID, what is it and what is it used for?
Under normal circumstances, a source device (digital and analog) will require information
about a connected device/display to assess what resolutions and features are available. The source
can then cater its output to send only resolutions and features that are compatible with the attached
device/display. This information is called EDID (Extended Display Information Data) and a source
device can only accept and read one EDID from a connected device/display. Likewise, the source
can only output one resolution for using by a connected device/display.
Why does EDID so important with the HDMI Matrix?
The Matrix is complex piece of technology that replicates and switches between multiple inputs
and outputs. Each connected source device will require one EDID to read. EDID management is
carefully handled by HDMI Matrix to provide a single EDID for each source to read.
What options do I have to manage the EDID in the HDMI Matrix?
First, it is important to know that each source device can only output one video/audio signal. It
includes resolutions and timings. When multiple devices/displays are used, such as with the HDMI
Matrix, it is important to use devices/displays that have similar or compatible resolutions/features.
This will ensure that the single video/audio signal produced by the source device is accepted by
the entire connected output devices/displays. The user has the option to choose how the unit will
manage the EDID from multiple HDMI devices/displays through the EDID management window.
Therefore the user has some control over the resolutions/features that the source devices will output.
The HDMI Matrix for has a multiple EDID management modes that will control how the EDID
information from multiple devices/displays are combined, ignored, and routed.
