The TripleHead2Go Digital SE External Adapter from Matrox is an external multi-display adapter which allows you to add up to 3 DVI monitors to your laptop or desktop computer. It connects to the video output of your system and uses the system's existing Graphical Processing System (GPU) to provide high-quality, uncompressed graphics and video across all monitors. The adapter maximizes your productivity when you are working with multi-screen setups, providing more desktop space. It also allows you to run different applications on each display or view one application across multiple monitors. It drives a stretched desktop with a maximum resolution of 5760 x 1080 (3 x 1920 x 1080) or 3840 x 1200 (2 x 1920 x 1200) across 3 or 2 displays respectively.
