Matrox Graphics today announced the Matrox TripleHead2Go Digital SE external multi-monitor adapter, which expands a computer's single-video output into a triple-monitor setup. The new Graphics eXpansion Module (GXM) connects to a compatible system's DisplayPort or Mini DisplayPort video output or Thunderbolt port and lets you add three external DVI monitors, each with maximum resolutions of either 1920x1080 at 50Hz on Windows or 1360x768 at 60Hz on OS X.
