Matrox made some waves with their GXM (Graphics eXpansion Modules) when they where first released, starting with the DualHead2Go. This module enabled dual monitor use with a single output. Their newest addition is the DualHead2Go Digital, which uses DVI as output method to allow higher resolutions. We try the device in Windows XP and Mac OS X using two 19 inch DVI based LCD montors.
