How to Set Up Dual Monitors on Your PC

Learn how to set up dual monitors on a desktop or laptop. Many new graphics cards and PCs have the ability to use more than one monitor. You can use VGA, DVI or HDMI to connect a second monitor. With dual monitors, you can clone the main monitor (i.e. display a presentation), switch between 2 monitors (i.e. use an external monitor instead of the laptop), or configure each monitor for a different task at the same time.
