EDID. What is it and what is it used for?

Under normal circumstances, a source device (digital and analog) will require information from a connected

device/display to know 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 to 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 has a multiple EDID management

modes that will control how the EDID information from multiple devices/displays are combined, ignored, and

routed.
