Extramon lets you use a second computer as a second monitor, giving you a dual-monitor computer. In fact, both of your computers become dual-monitor computers. And you can operate them both from a single keyboard and mouse. No hardware or cabling needed. All you need is two networked computers sitting side-by-side. Extramon sends video across the network and displays it on the other computer's monitor. Windows thinks that each of your computers has two monitors. Extramon has an on-screen switch that allows you to choose which computer you're looking at. You can turn off dual-monitor mode at any time and just operate each computer individually from a single keyboard and mouse.
