Congratulations on your purchase of the DVI DL 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 pro-
ductive and less expensive.
KVM switches allow access to multiple computers from a single keyboard, while the ex-
tenders give the user control over a computer up to 330 feet away from the work area.
The line offers solutions for noise, space and security concerns, data center control,
information distribution, conference room presentation, and school and
corporate training environments.
The DVI DL Splitter allows computers with Dual Link DVI graphic cards to be connected
to one or two Dual Link DVI compatible monitors or projectors.
The DVI DL Splitter also lets you keep your Dual Link DVI monitor next to your
computer, while adding a second Dual Link DVI display such as a projector or another
Dual Link DVI monitor.
Our Commitment
Gefen will always offer the finest quality product at the best possible price. Included in
that price is a lifetime of support from a team of outstanding engineers.

long cables for better picture quality. By turning the equalization knob counter-clockwise
you will eliminate any noise and/or degradation in the signal.You should be able to find a
