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 use by a connected device/display.
Why is 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 note that each source device can only output one video/audio signal type. This 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 all of the connected output devices/displays. The user has the
option, through the EDID management window, to choose how the unit will manage the EDID from multiple HDMI
devices/displays. 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.
