Hi, I'm Richard product owner at
Plugable. Today I want to talk
to you about one of our long
awaited new docking stations.
The UD-3900C4.
Here we show you four 1080P
displays connected to a single
host computer.
Using a single USB-C cable.
That also provides charging for
the laptop battery. And I'll
show you that these are all
connected. If I drag this window
from display to display, It
comes out just fine. Looking at
the back of our Docking Station,
you can see there are four HDMI
ports, all of which can be used
for connecting displays. The
HDMI ports one and two are
connected via DisplayLink
technology over USB 3.0 data
connection, HDMI ports three and
four are powered directly by the
systems GPU using
DisplayPort Alternate Mode over
USB-C with multistream
transport. Also known as MST
enables two displays connected
to the systems Graphics
Processor.
In terms of display resolutions,
all four of the HDMI ports
support resolutions up to 1080P
at 60 Hertz.
As if four displays was not
enough, this Docking Station
also supports power delivery for
laptop charging up to 96 Watts.
This is available as part of the
USBC power delivery. 3.0
standard.
One thing to note is that
charging over USBC is very
flexible. The power delivery
controller in the dock will
negotiate with the one in your
laptop to find the best common
charging rate. No need to go
hunting for system specs for
your laptop manufacturer. To see
if 96 Watts is an exact match
for your OEM charger.
The UD-3900C4 also provides vast
expandability with four USB 3.0
ports, gigabit ethernet, and on
the front of the unit 3.5
millimeter stereo audio, in and
out an SD 4.0 card reader.
And the USBC port capable of USB
3.0 data connectivity along with
an additional 20 Watts of USB-C
power delivery to charge your
phone or tablet rapidly.
All of this has packaged into a
very sleek design that would
look fantastic on anyone's
desktop. And maybe the coolest
thing is all of these features
are enabled with a single USB-C
connection between the dock and
your laptop.
Now let's talk a little bit
about compatibility. If you're a
Mac user, unfortunately apple
does not support MST. So what
that means is with this docking
station, you would only be able
to connect three displays.
We're using MST on the
displayPort alt mode video
signal that allows for multiple
displays to be connected to your
computers GPU through a single
video stream. As such, you will
want to make sure that your
laptop has the latest graphics
drivers for your manufacturer
for extending multiple displays
through the HDMI three and four
ports.
For the HDMI one and two ports,
please note that this requires
the installation of a
DisplayLink USB graphics driver,
which is typically installed
automatically via windows update
and requires a manual
installation on Mac.
Check out our website for
detailed installation
instructions for each platform.
