Congratulations on your purchase of the 8x8 DVI Matrix. 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 DVI Matrix
Now you can easily combine eight cross-platform computers and eight digital
displays without networking. Our 8x8 DVI Matrix 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 DVI inputs and eight DVI outputs. You simply connect
your eight computer DVI ports to the 8x8 Matrix inputs, then connect your eight
DVI displays to the 8x8 Matrix outputs.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 8X8 DVI MATRIX
• The 8x8 DVI Matrix is HDCP compliant when used in EDID pass-through
mode (when a single DVI input is mapped to a single DVI output). Additional
Matrix outputs which attempt to route video signals to a source device that
has already made an HDCP connection with an HDCP-compliant display will
not be able to display an image.
• By default, EDID routing is based on the first connected source and display.
For example, if monitor A is the first 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 DVI Matrix. 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.

Monitor Output’s are labeled 1 through 8 on the rear panel of the 8x8 DVI
Matrix. These numbers correspond to the lettersAthrough H on the LED Status
Display. The top row of letters will remain static while each input number below
will represent which source each of the displays are currently viewing.
HPD (Hot Plug Detect)
Whenever a display is connected/disconnected an HPD event will occur. This
will be displayed on the LED Status Display. A2 stage status update will occur
whenever a HPD event occurs

Use the included RMT-848IR remote control to route video to the different
displays.
