Congratulations on your purchase of the 1:2 DVI SL Splitter. Your complete satis­faction is very important to us.

Gefen’s line of KVM (Keyboard Video & Mouse), DVI, ADC, USB, switches, ex­tenders, converters and hubs is designed to make computer use more comfort­able, more productive and less expensive.

KVM switches allow access to multiple computers from a single keyboard, while

The 1:2 DVI SL Splitter also lets you keep your Single Link DVI monitor next to
your

another Single Link DVI monitor.

ed in that price is a lifetime of support from a team of outstanding engineers.

CONNECTING AND OPERATING THE 1:2 DVI SL Splitter

How to Connect the 1:2 DVI SL Splitter to your devices

1- Connect the supplied Single Link DVI cable from the back of the computer into
the input of the 1:2 DVI SL Splitter.

2- Connect the cable from your fi rst display (monitor or projector) into the DVI Out
1 slot on the 1:2 DVI SL Splitter. (this will be what the computer will recognize)

3- Connect the cable from your second display (monitor or projector) into the DVI
Out 2 slot on the 1:2 DVI SL Splitter.

4- Plug the 5v power supply into the 1:2 DVI SL Splitter.
5- Plug the 5v wall mount power supply into the wall outlet.
6- Restart your computer only after you’ve made all the connections. Please see

the paragraph explaining the function of the Equalization knob under the diagram
of the product below.

7- Adjust the EQ to resolve any imperfections in the image.

*Note: Only output #1 of the 1:2 DVI SL Splitter is HDCP pass-through.

The external equalization knob can be used to equalize the incoming signal
resulting from long cables for better picture quality. By turning the equalization
knob clockwise or counter-clockwise you will eliminate any noise and/or
degradation in the signal. You should be able to fi nd a “sweet spot” somewhere in
the middle.

Internal equalization control for the 1:2 DVI SL Splitter

Internal Equalization Knob for DVI Output 1

Internal Equalization Knob for DVI Output 2

The internal E.Q. knobs can be reached by removing the 6 hex nuts on the DVI
connections and the 4 screws on the bottom of the unit.

These E.Q. knobs control the pre-emphasis on the outgoing video signal and will
equalize the image, especially for long cable runs.

If you can't get the video noise to clear by adjusting the external equalization trim
pot, you can adjust the internal equalization trim pots to remove video noise per
each output.
