The DualHead2Go from Matrox is a revolutionary new device that allows you to add multiple independent monitors to your laptop or PC.
Simply plug the DualHead2Go into your existing VGA out port, connect up to two VGA monitors to the DualHead2Go, and install the included multi-desktop-management software. You'll immediately be able to double, or, if you have a laptop, even triple your current desktop space.
The Matrox DualHead2Go uses the output from your existing graphics hardware without loss of image quality or processing speed, so the more powerful your graphics card is, the better your multi-display environment will look. The DualHead2Go supports resolutions up to 2560 x 1024 in 16.7M colors at 60Hz stretched across two displays.
