Congratulations on your purchase of the ex•tend•it DVI Hub. 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 ex•tend•it line offers solutions for noise, space and security concerns, data center
control, information distribution, conference room presentation, and school and
corporate training environments.
The ex•tend•it DVI Hub allows computers with DVI graphic cards to be connected to one
or two DVI compatible monitors or projectors.
The DVI Hub keeps your desk clutter-free, relocating your computer to a safe and se-
cure area, while allowing you to work in a quieter environment.
The DVI Hub also lets you keep your DVI monitor next to your computer, while adding a
second DVI display such as a projector, another DVI monitor, Plasma display or analog
monitor.
Our Commitment

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