How to Set Up Triple Monitors

By Brian Gallagher

Having multiple computer monitors can greatly increase your screen real estate, improving your productivity and overall computing experience. With a powerful graphics card you can run three computer monitors simultaneously from a single computer. A multi-monitor setup has a variety of applications, especially in Audio/Video production and graphic arts.

Things You'll Need

  • A video card with triple monitor support
  • Three computer monitors
  • Necessary video cables (HDMI, DVI etc.)

Step 1

Make sure that you have a video card that can support three monitors. The card should have three video outputs, such as two HDMI and one DVI output.

Step 2

Make sure your video card drivers are up to date. Visit the manufacturer's website for driver update details.

Step 3

Obtain three LCD/LED displays that have corresponding inputs to your video cards outputs. For example, if your video card has DVI and HDMI outputs, make sure you have monitors that support these inputs.

Step 4

Plug the correct video cable into each monitor input and the corresponding video card output. Turn on your computer and displays.

Step 5

Right click your desktop and select "Screen resolution." Click "Detect." All three of your displays should be identified.

Step 6

Configure your displays with the desired screen resolution. Select one display as the "Main Display." You can drag windows onto the other displays from the main display.
