INTRODUCTION

Congratulations on your purchase of the 8x8 Matrix for HDMI. Your complete
satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.

The Gefen 8x8 Matrix for HDMI

Now you can easily combine eight cross-platform computers and eight digital
displays without networking. Our 8x8 Matrix for HDMI provides a simple, reliable
and highly effective method of creating multiple computer workstations, with each
workstation capable of accessing any one of the computers or sources at any
time by remote control. You also have the option of setting up the eight stations
locally or extending them with a Gefen extender.

How It Works

The 8x8 Matrix has eight HDMI inputs and eight HDMI outputs. You simply
connect eight computer HDMI ports to the 8x8 Matrix inputs, then connect eight
HDMI displays to the 8x8 Matrix outputs.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 8X8 MATRIX FOR HDMI

• The 8x8 Matrix for HDMI is HDCP compliant when used in EDID pass­through mode (when a single HDMI input is mapped to a single HDMI
output). Additional Matrix outputs which attempt to route video signals to a
source device that has already made an HDCP connection with an HDCP­compliant display will not be able to display an image.

• By default, EDID routing is based on the fi rst connected source and display.
For example, if monitor A is the fi rst display to connect to source 1 its EDID

will be used. All other displays that connect to source 1 thereafter will
have its EDID ignored. If display 1 switches to another source a hot-plug
signal will be sent and the EDID from the next display that is connected, in
numerical order, will be used.

• The Status Output display will only list the current display/source routing.

• There is no internal scaling in the 8x8 Matrix for HDMI. All of the attached
monitors must be able to display the resolutions output by the source
devices. For maximum compatibility it is recommended that only one
compatible/common resolution be used by all of the source devices.
