4. Operation

LED Indicator

The Power LED turns green when the video switch is powered on. When a video port is selected,
its corresponding Port LED turns yellow.

Push Button

Press the corresponding button to select a port.

EDID Setting

In some cases, display problems may occur because of incorrect Extended Display Identification
(EDID) communication between the display monitor and the unit. This function allows the
system either to read the necessary EDID information from the unit, or to copy EDID from
EDID-compliant displays.

Default Setting

To reset to the default EDID:

Step 1:

Press and hold the “EDID Copy” button on the unit and release the button RIGHT AFTER

the Power LED flashes red (6–7 seconds).

Step 2:

The LED lights steady red and green indicating that the EDID default setting is completed.

Copy (New) Monitor EDID

When using a monitor (EDID-compliant) for display, the unit’s EDID Copy function will enable

EDID communication between the monitor and the unit for optimal video quality. Follow these
steps:

Step 1:

Power on the unit.

Step 2:

Connect the EDID-compliant monitor to the switch and power on the monitor.

Step 3:

Press the “EDID Copy” button for 3–5 seconds, and release the button RIGHT AFTER the

Power LED flashes green.

Step 4:

The Power LED flashes red and green alternately, then lights green indicating that the

copy is successful.

NOTE: If the Power LED flashes red, the reason could be:
1. The monitor is not connected.
2. The monitor is not powered on.
3. The EDID data of the monitor is not applicable.
