Matrox has updated its line of DualHead2Go external multi-display adapters with the simultaneous release of the DualHead2Go Digital SE and DualHead2Go Digital ME (Mac Edition). While both the SE and ME let users connect up to two monitors, the SE model features multi-GXM (Graphics eXpansion Module) support that allows two adapters to be connected to a single system to provide a total of up to four displays.
