Matrox Graphics on Monday announced the availability of PowerDesk, desktop management software intended for use with its Graphics Expansion Module (GXM) devices on the Mac. It’s available for free download from the Matrox Web site.
Graphics Expansion Modules are external boxes made by Matrox, branded as the DualHead2Go and TripleHead2Go. They enable you to connect two or three displays to your Mac using only a single video interface on the Mac — useful for laptop systems, Mac minis and iMacs — systems that only feature a single video output jack.
PowerDesk improves how applications are managed on GXM-based multi-monitor setups. You can use PowerDesk to control where windows appear on your desktop, reposition the dock on an external monitor, and modify resolution settings.
