DualHead2Go and TripleHead2Go are external multi-monitor upgrades that let you connect two or three monitors to your laptop or desktop computer. They attach to the video output of your system and use its GPU to provide high-quality, uncompressed graphics and video across all monitors. These little black boxes are perfect for bringing multi-monitor functionality to laptops, systems with integrated graphics or with no available expansion slots, or systems that are already closed and validated.
