EDID Management
Operating the 4x4 Matrix for HDMI 1.3
External EDID
When set to Ext mode, EDID data will be fetched from the sink that is connected to HDMI
Out 1
. It is recommended that the display with the lowest native resolution be connected
to HDMI Out 1 . This ensures that a compatible video signal will be output to all connected
displays.
1. Select the external EDID mode. Refer to Selecting the EDID Mode (page 15) .
2. The Ext LED indicator on the front panel will be illuminated.
3. Press and release the Reset button on the front panel of the matrix to reset the unit.
The matrix must be reset (or power-cycled) each time the EDID mode is switched.
When the external EDID is used, the following rules apply:
► The 4x4 Matrix for HDMI 1.3 will always attempt to read the EDID from the sink
device connected to the Out 1 port and copy it to the In 1 port. Out 1 is the
(default) primary output port.
► If a sink device is
not
detected on the primary output port, then the matrix will
sequentially scan all subordinate output ports (2, 3, etc.) until a sink device is
found. Once detected, this subordinate output port will become the new primary
output port and the EDID will be copied to the In 1 port.
This state will be in effect until a sink device is connected to the Out 1 port and
the matrix is power-cycled or the Reset button is pressed.
► EDID capabilities (timings, audio, color depth, etc.) will be supported by all
subordinate sink devices only if they are supported by the primary sink device.
► Operational / compatibility issues may result if a subordinate sink device is
unable to support the EDID capabilities of the primary sink device.
