The EDID learning function is only necessary whenever you have a display on the DVI output
port that cannot play video correctly. Because DVI sources and displays are capable of
outputting various resolutions, the Matrix will always output the lowest resolution from all the
connected devices. To correct this problem you can force the Matrix to learn the EDID from the
lowest resolution display connected by performing the following procedure:
1. Using the front buttons, select both the Input and output ports of the source and display
with the lowest working resolution.
2. Press and hold the + button of the output port and the – button of the input port for 2
seconds.
3. When you release the buttons the EDID of the display connected will be written to the
connected input port.
4. If the procedure was successful the LED of the input ports will show a zero "
was unsuccessful then it will show an F " ".
To restore the default EDID to any specific port, perform the following procedure:
1. Select the input you want to restore the default EDID to and match the LED on the output
port (not input port)
2. Press the + buttons on both the input and output at the same time for 2 seconds.
3. When you release the buttons the default EDID will be restored to the input port.
4. If the procedure was successful the LED of the input ports will show a zero "
was unsuccessful then it will show an F " ".
