LaptopLogic (dead link) reviews Matrox DualHead2Go and concludes with editor rating of 4 out of 5 that “DualHead2Go is an innovative product that fills a need for many consumers, in both business and home environments. It provides a simple solution for individuals that have systems which are unable to support a dual monitor output, or if they need a total of three screens on a laptop. The retail $169 price point is actually reasonable compared to other solutions. For example, the SideCar Express dual monitor adapter sells for $1299. Matrox has produced a high quality product that is easy to install and use by almost anyone. Anyone who is looking to expand their desktop real estate or increase productivity, the Matrox DualHead2Go is THE device to use. We hope to see a digital DVI model in the future.”
