Matrox TripleHead2Go
Digital Edition
By Nels Anderson
Flightsimmers are on a never-ending quest to turn
their computer into an ever more realistic simulation of
an aircraft and the cockpit flight environment. Microsoft
Flight Simulator claims to be "as real as it gets" but
there's always more that can be done. Any flightsimmer needs the basics like a yoke and rudder
pedals. Beyond that there aredevices that will let you
feel
the sim in action as well as watch and hear
it and even hardware that will let you simulate a realistic set of cockpit avionics and controls.
All of these things make the sim more fun to use. But one of the greatest weaknesses of any sim is
the limited visual aspect. Human vision has a field of view close to 180 degrees and even though
we're only able to see sharply in a much smaller area directly ahead that wide field of vision does play
an important part in any activity. Unfortunately, a standard computer setup limits our view to that
displayed on a single video or LCD monitor so flightsimming that way is kind of like flying an airplane
while looking down a tube. Though what appears on the screen is quite realistic, the overall view is
not.
Various means have been devised to deal with that, starting with the simple ability built right into the
sim itself to zoom out and show a wider field on that single screen to virtual cockpits that allow you to
look around in any direction; this can be done with top hat buttons on a yoke or joystick or much
more realistically using some sort ofhead tracking device. The head trackers help quite a bit but still
your actual field of view is limited to that one narrow screen.
Which brings us to the subject of our review, the Matrox TripleHead2Go Digital Edition which is
nothing more than a black box that lets your computer drive three monitors instead of just one,
immediately tripling your visual field of view.
The Digital Edition is the latest member of the Matrox "GXM" (Graphics eXpansion Modules) family
where earlier versions offered expansion from one to two monitors or operated with analog signals
instead of digital. This latest version connects either a dual-link DVI or analog signal from you
computer to three monitors. The monitors plug into the TripleHead2Go with a DVI connector (if your
monitor has an older analog connector adapters are available). With this setup you can now have a
display of up to 3840 x 1024 resolution using three monitors.
