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 connec-
tions.

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 connection 

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 dis-
play 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 automati-
cally uses a default profile.

To efficiently achieve EDID communication when the video source 
is booting up, configure the EDID on the splitter before operation.
