The Matrox TripleHead2Go DP Edition is a unique new multi-display adapter that enables a\u00a0laptop or desktop computer to power up to three monitors. Also known as a GXM (Graphics eXpansion Module), the TripleHead2Go DP Edition connects to\u00a0a computer's\u00a0DisplayPort video output\u00a0port. Video signal from the computer\u00a0is then split up by the TripleHead2Go and funneled\u00a0to\u00a0as many as three\u00a0connected monitors.\n\tThe TripleHead2Go makes it possible for laptops to be used with multiple external displays,\u00a0and its\u00a0use of the connected computer's\u00a0GPU allows for exceptionally smooth performance.\u00a0And because it's an external adapter,\u00a0TripleHead2Go eliminates the need to meddle with its insides to install an additional graphics card, for example.\n\tMy three LCD displays connected to the Matrox TripleHead2Go DP Edition using the (optional) DisplayPort to DVI adapters.\n\tDisplayPort input from the laptop\/desktop on the left, and USB port for power\/configuration on the right.\n\tSetting up the Matrox TripleHead2Go DP Edition\n\tThe TripleHead2Go DP Edition package includes the TripleHead2Go device, a 2-foot DisplayPort to DisplayPort cable, a USB cable for power and a DisplayPort-to-mini-DisplayPort adapter.\n\tI used a Dell XPS 13 Ultrabook with a built-in mini DisplayPort output for my tests. It was easy to\u00a0connect the various cables, and the gadget comes with an illustrated instructions\u00a0guide.\u00a0My Dell\u00a0XPS 13 doesn't have an optical drive, so I downloaded the latest driver from the Matrox website and\u00a0launched the Matrox GXM Quick Setup utility after installation. The utility\u00a0told\u00a0me to connect\u00a0all monitors and it automatically detected my three LCD displays. I rebooted my system as required, and all three monitors worked after that.\n\tMy\u00a0Ultrabook was only able to power the three displays at a relatively meager 1360x768 resolution - a limitation of its GPU rather than the TripleHead2Go. When I unplugged one of them the remaining two LCD displays operated at their maximum 1920x1080 resolution.\u00a0Performance will\u00a0probably vary with other laptops, depending on the GPUs.\n\tThe mini DisplayPort adapter connects\u00a0the TripleHead2Go DP Edition to\u00a0my computer. On the left is the USB port used to configure and power the gadget.\n\tThe TripleHead2Go DP Edition appears as a gigantic 4080x768 external monitor.\n\tTripleHead2Go Advanced Features\n\tThe TripleHead2Go DP Edition is the latest in a line of GXMs made by Matrox, and is supported by a strong software suite. It has\u00a0bezel-management capabilities to compensate for gaps in the extended display created by the bezesl of monitors. I particularly like how the Matrox PowerDesk software allows for invisible demarcations to be made over the various displays; when maximized, application windows\u00a0snap to fill up the virtual lines, which can span multiple monitors.\u00a0The device works with\u00a0PCs and Macs, and\u00a0it is also compatible with MacBook Pro laptops with the new Thunderbolt port.\n\tConclusion: Matrox TripleHead2Go DP Edition\n\tThere's a lot to like about the\u00a0TripleHead2Go DP Edition, though its $329 price tag is a bit of a turnoff. It's just as simple to\u00a0setup and configure as the previous GXM units\u00a0from Matrox, and it comes in a slightly smaller form factor.\n\tBefore buying, users\u00a0should download the System Compatibility Tool to ensure that their computers'\u00a0GPUs are\u00a0capable of supporting the TripleHead2Go.
