In today’s working environment it essentially that users have access to more than one or even two monitors when working with a computer. There are a lot of ways to do this but the key piece of software is Displaylink. This software allows you to connect USB Video adapters to a monitor and then your pc to get an extra monitor. Most laptops and desktop support two monitors, but what if you want three or four or five? That is where display link comes in, with the addition of a usb video adapter or even a docking station. For me I use 4 monitors, my laptop screen and three 23 inch monitors. For more information please click on this link.
