it depends on the operating system you are running...but in a nutshell, you might have to change around some bios settings (setting primary video or somthing)...if not, then you install the drivers and restart and when you open up display properties (right click on desktop wallpaper) there should two monitor showing under the settings tab...you then have to 'extend your desktop' to the other monitor and set both monitors up...this stuff is easier than it sounds...give it a go and respond with more questions if you need to....bn3
