Real-World Experience
When this unit arrived, I unpacked it and plugged in the AC Adapter. Then I took
an RJ45 network cable off my cable router and plugged it into the back of the
unit. Then I took a DVI video cable from my big desktop monitor and plugged the
other end into the back of the unit (It only accepts DVI, but if you've only
got VGA you can buy an adapter plug for as little as $5.00). Finally, I took
my wireless keyboard / mouse USB radio dongle and plugged that into the unit. You
can leave all these plugs the way they are, you will never have to change them
again. If you do not have a wireless keyboard / mouse, just plug your keyboard
and mouse USB plugs into the unit.
Finally, I put my HP Pavilion DM3 notebook on my desk, plugged in the AC, and stuck
the single USB cord from the unit into one of the USB ports on the notebook. Powered
on the notebook, logged in, and the DisplayLink software dialog came up. All
the software and drivers are right in the HP USB Docking unit; they install automatically
-- which is great, because many notebooks today do not have an optical drive.
I should mention that although this is an HP product, it should work with virtually
any brand of notebook that supports USB 2.0.
As soon as the software was installed, which took only a minute, I hit Windows-P
to select "Projector" and hit the DVI switch on the front of my monitor.
Immediately I had a full-screen display from the notebook, which was crisp and
clear (that's on a 24 inch monitor) and full access to my wireless keyboard and
mouse. I plugged in the printer, too, and verified that it worked. In short, with
a single USB plug, my notebook was now a desktop PC! I don't know how they can
get so many signals to come over a single USB plug, but it works and there is
no loss of speed or connectivity at all.
All I can say is, if you've got a notebook computer that you'd like to be able to
use as a full desktop PC, and you want the ease of plugging it in and going to
work immediately with nothing but a single USB plug, this is definitely the way
to go. Need to go out on a job? Unplug the USB and take your notebook and AC
adapter along, and you're off! When you get back home, just plug in the USB
and your AC Adapter and you have a full desktop PC, instantly. No more messing
with video plugs, network cables and the like.

Nowadays programmers and IT workers are using more high-powered notebook computers
with more RAM and bigger hard-drives that can easily double as a desktop PC.
The big problem up to now was that unless the notebook is equiped with docking
capability and came with a docking station, the frustration of having to connect
and disconnect monitors, network cables, mouse and keyboard made doubling the
notebook as a desktop a frustrating experience.
A flexible computing environment helps you stay productive, whether you're working
in your main office, a satellite office or a home office. The HP Universal Docking
Solutions for HP Notebook PCs use universal USB technology to pass through critical
signals such as video (HP USB Docking Station 2.0 only), LAN and peripheral connectivity
(keyboard, mouse, printer).
Since USB is a widely adopted industry standard, the HP USB Docking Station 2.0 is
perfect for notebook computers that don't have an integrated docking connector.
Users can just plug the dock into the USB port and extend their notebook for
a true desktop experience.
Versatile Connectivity
Enjoy immediate audio and network connectivity, plus improve your productivity with
access to up to five concurrently working universal serial bus (USB)-connected
devices. Over a single USB cable, you can connect your notebook to a keyboard,
mouse, printer and other accessories that you regularly use, giving you a true
desktop experience!
Smart and Flexible
The HP USB Docking Station 2.0 is designed to bring maximum productivity to users
with minimal installation issues. Unlike other docking stations, the HP device
has flash memory with installation-ready software drivers that detect when a
computer is connected and guide users through a simple installation wizard. There's
no need to install software from a CD, another benefit for notebook computers
that do not have an optical drive.

little as $5.00. Here's one at Office Depot.

Summary
The HP USB 2.0 docking station, at less than $100.00, is a steal. It's solid, reliable
and trouble-free. Installation is a breeze. Highly recommmended.
