Matrox Graphics Inc. offers TripleHead2Go, an external upgrade that adds support for using 3 monitors at a time. The easy-to-install unit simply connects to the monitor output of a computer. The operating system treats TripleHead2Go like a monitor supporting resolutions 3 times as wide as standard resolutions and TripleHead2Go uses Matrox technology to divide the monitor output from the computer into 3 separate displays. The displays respectively show the left, center, and right portions of this "monitor".
