It was not long ago that a multiple monitor setup was reserved only for those who could splurge the extra cash for the setup. That can no longer be said since prices for monitors and graphics cards have dropped by such a significant amount that doubling the number of monitors on your PC will cost you less than buying a fancy smartphone or a tablet. There are a lot of benefits to having a multiple screen setup the obvious is an increase in your desktop screen real estate. An increase in your work space can lead to an increase of productivity. Entertainment-wise, a multiple screen setup will allow you to play your favorite game on one screen, keep track of your Facebook and Twitter account on another, and perhaps a movie on the third screen, all without pressing alt + tab as you would normally do when running your PC on a single screen.
The all-important graphics card is the key to setting up a multiple monitor display for your PC. Most graphic cards today support multiple displays of a maximum of two displays, one for DVI and the other for VGA. If you are looking to add more than two monitors, there are more advanced graphics cards that will allow you to do so. Though some graphics cards have three video outputs, they can only drive two displays at a time. You need to check the specifications and capabilities of the card from the manufacturer before purchasing.
Doing an upgrade on your PC’s graphics card for a multiple display setup is advisable if you are doing a good amount of gaming, graphics rendering, or video editing. However if you are only up for some office work, web browsing and basically your run of the mill PC tasks there are options that are less expensive than buying a new graphics card. One option is to buy an external graphics module that will enable you to add two or three monitors from a single VGA or DVI output. Another option is to buy a similar USB external graphics module, but this time instead of running the graphics off a VGA or DVI port, it would use a USB port. These options will allow for a multiple display setups for PC tasks that do not require additional resources for video processing.
The monitor for your multiple-display setup can be configured in a number of different ways. There is no requirement as to what type of monitor you purchase, only that the video connectors should accommodate that of the graphics card. Preferably, you want to choose the same brand and model as your current monitor for easier setup and aesthetic purposes. The second display can be set in a portrait orientation, this makes it easier to view long documents and web sites and reduce the amount of scrolling needed.
Now that you have your hardware all setup, all you need to do is to configure your PC to work with the monitors installed. At first you will have a mirrored display for your multiple displays, all you have to do is to go to the display settings for windows in the control panel and head to the multiple display option.
