In this instructable I'll be showing you how to setup two (or more) monitors with Microsoft Windows Vista. This is a handy trick to know if you're needing more space to work with and can really increase your productive use of your computer. What we'll be doing is hooking up the second monitor, extending the desktop across the second screen, and calibrating the display. It's all pretty basic and simple to do. If you're experienced with computers then this will seem like a needless instructable to you but if you're unaware of how to do this then it'll be a little bit of an eye opener.
Step 1: What you need
In order to be able to do this you will need a computer with at least two video cards, Microsoft Windows Vista (you don't need this, but this instructable was written for Vista), two monitors, and the cable to hook up the second monitor. I'm using a laptop that has a preinstalled auxiliary video output that doubles as a second video card (the laptops LCD and associated hardware counts as one) so I just used that one. If you're using a laptop then all you'll need to do is connect your second monitor to your external display port. If you're using a desktop then you'll need to purchase and install a second video card.
Step 2: Turning on the second monitor
Once you're connected your second monitor the first thing that you'll notice is that it isn't doing anything. This is normal. You just need to tell the computer how it's supposed to be using this second monitor. If you're using an updated version of Vista then it will have already detected the second monitor, so there's no need to do any hardware configuration. The next thing you'll want to do is minimize all of your open windows, right click on the desktop background, and click on "Personalize". This will pull up the "Personalize appearance and sounds" window. From here you will click on "Display Settings". This will open the Display Settings program.
