Setup is very simple. Start with your machine powered down and connect all the cables (2 output cables, 1 input cable, and power cord) to the DualHead2Go. Once you're all plugged in, power up the computer and install the supplied Matrox software when the computer is ready. Once installed, open up your Display properties (in Control Panel or by right clicking on your desktop) and increase the resolution of your display. If you have a native resolution on your display of 1280x1024, you should be able to increase the resolution in your display properties to 2560x1024..
