EDID MODES
EDID. What is it and what is it used for?
Under normal circumstances, an 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 an only output one resolution for use by a
connected device/display.
Why is EDID so important with the 4x4 Matrix for HDMI 1.3?
The 4x4 Matrix for HDMI 1.3 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 4x4 Matrix
for HDMI 1.3 to provide a single EDID for each source to read.
What options do I have to manage the EDID in the 4x4 Matrix for HDMI 1.3?
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 4x4 Matrix for HDMI 1.3, 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 a switch on the rear panel of the unit, to change
between a external EDID (provided by the display connected to HDMI output port
labeled OUT 1) or a pre-programed internal EDID.
How do I change EDID modes in the 4x4 Matrix for HDMI 1.3?
Simply change the switch on the back panel of the 4x4 Matrix for HDMI 1.3 to
the desired EDID mode. The unit must be reset once the EDID mode has been
changed. Please press the RESET button on the front panel once the EDID
mode has changed.
