How to Setup Your Computer for Dual Monitors


I’m loving the dual-monitor computer system Lenovo sent me for review and giveaway. In my opinion, most dads and moms will be more productive with two 19″ monitors instead of one super hugemongous monitor. With two applications side by side on my 22″ screen, I have to scroll horizontally and vertically. But with two 19″ Lenovo displays, I can maximize an application on each screen and rarely have to scroll sideways. And if you have a home office like this geek dad, you can stream an ESPN game on one monitor while you work on MS Word or Excel on the other screen. Just don’t tell the boss.

As some geek dads know, Microsoft Windows 7, Vista, and XP has built-in support for multiple monitors (see my how-to instructions for dual displays). However, not all desktop computers have the hardware to support multiple displays. Your computer needs two Video Graphics Array (VGA) connectors, two Digital Visual Interface (DVI) connectors, or one of each. That’s one of the things I like about the Lenovo ThinkCentre A63 tower computer and ThinkVision L1951P LCD monitor — they have two video ports (VGA and DVI). [Note: the Lenovo ThinkVision LCD displays also come with both VGA and DVI cables.] If your PC only has a single video connector, you will need to upgrade the video, buy a second video card, or purchase a USB to DVI/VGA adapter.

If you have a spare monitor and a computer with multiple video ports (like a laptop), follow the Microsoft Windows 7, Vista, and XP instructions below to set up two monitors on a single computer.
