Matrox Graphics Inc. now offers expanded monitor and graphics hardware support for its popular Graphics eXpansion Modules (GXMs). These easy-to-install, palm-sized, external upgrades add multi-display support to a system by dividing the monitor output of a computer into separate displays. The original DualHead2Go now supports the wide range of graphics hardware already supported with TripleHead2Go, including add-in cards from ATI Technologies and Nvidia, and SLI configured systems. With TripleHead2Go, in addition to existing support for 3 monitors at time, Matrox now provides support for 2 monitors at a time, wide screens, and higher refresh rates.
