    Dual-Monitor Display

    Many computers support a dual-monitor display, and I would bet that many people don’t even realize it. For instance, most laptops allow you to use the internal display and a monitor plugged into the VGA port at the same time. Many PC video cards support both VGA and DVI ports, both of which can typically be used at the same time. Newer PCs even allow you to insert more than one video card at a time.

    Why? Because you spend most of your computer time using one application — but that is not all you use. Your primary application may be a web browser, your e-mail client, a word processor, or perhaps even custom business software. Having two displays allows you to dedicate one monitor to your primary application, and use the other monitor when the occasional need to multi-task arises.

    You will also find dual displays useful if you need to reference one file while accessing another. For instance, when typing a report in Word, you need to reference a spreadsheet in Excel. Or perhaps you want to reference a web site when authoring an e-mail. Just think about times when you most often switch between open applications. Dual monitor displays may offer you an easy way to boost productivity.

    Windows XP and Windows Vista support multiple displays out-of-the box. The first time you boot your PC with both displays active, you may see the same image on both. Once Windows is running, open your display properties/settings to confirm that two monitors are visible to Windows. Then select the second monitor and enable the option “Extend my Windows desktop onto this monitor.”

      I plugged in a laptop to a tv display. the first time, it asked me if i wanted to display both monitors with the same image or as an extension. i first selected “same” and then switched to an extended by following your instructions above. But now i want to go back to the same image. Only problem is.. the option does not present it self again when i start over. And unselecting the box above changes nothing. Ideas?
