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

Connects two or three monitors to your system, and lets you see more, do more.
