How to Add an External Monitor to a Laptop

Almost all modern laptops, including the smaller netbook style notebooks, feature a 15-pin VGA monitor connector that you can use to add an external monitor to your computer setup. Whether you intend to use the larger, external monitor in place of your laptop screen for added screen real estate or as an additional desktop to be used in conjunction with your laptop, an external monitor can provide a variety of benefits to your laptop computing experience. For the most part, simply connecting the monitor to your laptop and powering it on is all you need to do. However, there are additional options that you can configure that will provide you with the ideal multi-monitor setup.
