FEA TURES
• Split your PC’s DVI signals to two or four
separate DVI displays.
• Accurately and reliably reproduce the
digital video signal without signal
attenuation and distortion.
• Support DVI-I (integrated analog and/or
digital) video signals.
• Include a DVI-I input cable and universal
power supply.
• Can be cascaded up to two levels deep
for additional outputs.
• Provide high digital resolution up to
1600 x 1200 at Hz.
• No software needed. Simple, plug-andplay installation, so you can link to DVIenabled monitors, projectors, or plasma
or LCD screens in minutes.
• Also work as amplifiers and extenders,
enabling you to locate your DVI
monitors up to 33 feet (10 m) from
your PC and still enjoy crystal-clear
digital images.
• Great for digital signage and training
applications.

display device, order a BLACK BOX
®
Digital Visual Interface
(DVI) Splitter.
Available in 2- and 4-channel models, the splitters enable
you to route a signal from DVI-capable PC to a plasma or an
LCD screen. Supporting a DVI-I video signals at a maximum
resolution of 1600 x 1200 @ 60 Hz, the splitters make it easy
to use your computer to show a high-resolution presentation
to an audience viewing a larger screen.
What’s more, you can also use Digital Visual Interface
Splitters as amplifiers and extenders, so you can locate your
DVI monitors up to 33 feet (10 m) from your PC and still
enjoy crystal-clear digital images.
Great for digital signage and training applications,
the splitters reproduce the DVI image without any image
distortion or signal attenuation.
There‘s no software needed. The splitters offer simple,
plug-and-play installation, so you can link to DVI-enabled
monitors, projectors, or plasma or LCD screens in minutes!
To add outputs to your application, just cascade multiple
units. Youcan cascade the splitters up to two levels deep
for a total of four or eight outputs. Splitters feature two
or four DVI-I input connectors, and one or two DVI-I output
connectors.
Digital Visual Interface (DVI) and other digital display interfaces.
P&D does, but it’s somewhat smaller. Manufacturers such as
Intel
®
, IBM®, Compaq®, HP®, Fujitsu®, and NEC®are backing
DVI technology, particularly the DVI-I connector type because
it can do what previously required separate analog and digital
connectors.
All these standards are based on transition-minimized
differential signaling (TMDS). In a typical single-line digital
signal, voltage is raised to a high level and decreased to a low
level to create transitions that convey data. TMDS uses a pair
of signal wires to minimize the number of transitions needed
to transfer data. When one wire goes to a high-voltage state,
the other goes to a low-voltage state. This balance increases
the data-transfer rate and improves accuracy.
The push is on to make displays digital, whether they’re
legacy Cathode Ray Tubes (CRTs) or newer Liquid Crystal
Displays (LCDs)—because a digital monitor provides both
excellent picture quality and higher bandwidth transfers.
There are three main types of digital video interfaces.
Plug & Display (P&D, also known as EVC), the earliest of
these technologies, supports both digital and analog RGB
connections and is now used primarily on projectors. Digital
Flat-Panel Port (DFP) was the first digital-only connector on
displays and graphics cards; it’s being phased out. There are
two types of DVI connectors in use: DVI-D and DVI-I. DVI-D
is a digital-only connector like DFP, but it offers much faster
data transfer and higher resolution along with power-saving
modes. DVI-I handles both digital and analog connections like
