The Gefen 1:8 HDMI Distribution Amplifier is the perfect solution for anyone who
needs to send one source of digital high definition video to multiple displays at the
same time. It supports all HDMI equipment, such as DVD players and satellite set
top boxes and all HDMI displays. In operation, the digital video source is connected
to the distribution amplifier’s one input while eight HDMI outputs are available to be
used in part or in full. Once the unit is connected and powered, your source can be
distributed up to eight digital displays at the same time.
How It Works
Simply connect your HDMI video source to the 1:8 HDMI Distribution Amplifier’s
input using the supplied HDMI cable. Then connect up to eight HDMI displays to
the unit’s eight HDMI outputs. Once connected and powered, your source can be
seen on all eight displays at the same time. When two or more 1:8’s are connected
together, you can create a larger distribution system.

Extended display identification data (EDID) is a data structure provided by a
display to describe its capabilities to any source that asks for it. The EDID includes
manufacturer name, product type, timings supported by the display, display size,
luminance data, (for digital displays only) pixel mapping data, supported audio
channels and formats. This information is used by the source to cater its output to
resolutions and audio formats that are supported by the display.
Additional EDID modes are available and configured using a combination of dip
switches 1, 2, and 5. Please refer below for the different EDID modes.
To access the Dip Switches, remove all screws from the bottom and sides of the
Gefen unit. Carefully slide the unit apart. The 8 Bank of Dip Switches are located
on the main PCB. Once adjustments are complete, slide the unit back together and
replace all removed screws.
