Use True Dual Monitors with Laptops
The advantages of using multiple monitors for desktop workstations are well established. Yet many who use a laptop as their primary workstation have not been able to enjoy the full benefits of multi-displays. While laptop users have always been able to connect a display to the video out port on the laptop, this is a half-step solution.
To solve this problem, Matrox has created a multi-display graphics upgrade that brings full multi-monitor capability to a laptop. The Matrox DualHead2Go external multi-display upgrade is not a graphics card, but rather a palm-sized box that sits outside of your system. The device takes the existing single monitor display output (i.e. external VGA output) from your system and expands it into dual display outputs, allowing you to run your Windows desktop at up to 2560 x 1024 resolution stretched across two displays. Using DualHead2Go in conjunction with the built-in display of your laptop, you actually benefit from three displays at a time.
We installed the unit in our office by connecting the DualHead2Go box to the video out port on our laptop docking station. We then connected two ViewSonic 19-inch monitors to the monitor out ports on the device. After installing the included Matrox PowerDesk software, we were able to seamlessly manage window positioning and message pop-up across both screens.
The DualHead2Go device uses the native graphics hardware already present in your system for all 2D, 3D, and video drawing. There is no loss of image quality or speed on your system. The more powerful your existing graphics, the more powerful your DualHead2Go multi-display environment. The device only works with specific graphic cards so you will want to check the Web site compatibility guide to make sure your laptop will work.
