Port 1 on the split ter and power on the monitor.
Step 2. Press the “EDI D COPY” button, then release it RIGHT
AFTER the L ED flashes GREEN and RED (about 3 seconds ).
Step 3. The LED returns to normal status indicating that EDID copy
is completed.
Otherwis e, if the Status LED flashes RED, it means that:
a. The monitor is not properly connected.
b. The monitor is not powered on.
c. EDID data of the monitor is not applicable.
3.2.3 EDID Factor y Default Setting
To set the EDID copy to factory default:
Step 2. Press the “EDI D COPY” button, then release it RIGHT
AFTER the L ED flashes GREEN twice (about 9 seconds).
Step 3. The LED returns to normal status indicating that EDID copy
is completed.
4. Operation
The quality of the output signal depends on the quality of video
source, cable, and display device used. Low-quality cables degrade
output signals causing elevated noise levels. Use the proper cable
and make sure the display device can handle the resolution and
refresh rate selected. Interference from nearby electrical devices can
adversely affect signal quality.

5. Troubleshooting
Symptom: Video does not display
Possible Cause: Wrong installation process.
Solution: The video splitter requires at least one monitor
connection before powering on the source device.
Symptom: Erratic behavior
Possible Cause: Splitter may not receive enough power.
Solution: Check the power adapter attached to the splitter to
make sure it matches the system specifications, and is functioning
pro perly.
Symptom: Not receiving picture or sound.
Possible Cause: The signal source may require a display device that
is HDCP compliant.
Solution: Check if the display monitor is HDCP compliant. H DCP
prevents the transfer of digital content to unauthorized H DMI
devices.
Symptom: The display monitor is added to the unit by hot-plug,
but the video source may not support hot-plug.
Possible Cause: Check if the video source suppor ts hot-plug. If it
doesn’t, shut down the source device and rebo ot it again. The
attached devices are not connected properly.
Solution: Check if you connected your components correctly.

3. Installation
3.1 Installing the Splitter
• Before installation, power off all devices that will be
connected to this system.
• Make sure that all devices you will connect are properly grounded.
• Place cables away from fluorescent lights, air conditioners, and
machines that are likely to generate electrical noise.
You will need one HDMI male-to-male cable to connect a video
source to the video splitter’s input port. Connect
multiple monitors or TVs to the video splitter’s output ports.
Turn on your video source only after you’ve made all the connections.
NOTES:
1. The splitter unit is HDCP compliant and required to use
an HDCP compliant display when it is connecting to the HDCP
video source.
2. Each output port on the splitter must apply the same connec tion
pattern when a DVI-to-HDMI (or HDMI-to-DVI) adapter is used
for HDMI (or DVI) signal conversion between the splitter and the
HDMI (or DVI) display.
Mixed (HDMI and DVI) output connections may cause
signal degradation.
3.2 EDID Configuration
Incorrect EDID communication between the display monitor and
the PC graphics card or insufficient EDID data programmed by display manufacturers may cause problems. The splitter provides many
ways to read EDID informationfrom the attached video display and
then provides it at all times to the attached video source. If no new
EDID information is available from a display, the splitter automatically uses a default profile.
To efficiently achieve EDI D communication when the video source
is booting up, configure the EDI D on the splitter b efore operation.
