How to set up a second monitor

Adding a second monitor to your computer can give you the extra screen real estate you need to get your work done. But how do you set it up?

Here’s a step-by-step guide to adding a second monitor to your computer.

  1. Turn off your computer and unplug all of the cables from the back. This includes the power cord, any USB cables, and the video cable.
  2. Find a spot for your second monitor. If you’re using a desktop computer, you can place the second monitor on top of your desk. If you’re using a laptop, you may need to invest in a monitor stand.
  3. Connect the video cable from your second monitor to the video port on your computer. If you’re using a desktop computer, you’ll likely have a DVI, HDMI, or VGA port. If you’re using a laptop, you may have a Mini DisplayPort, Thunderbolt 3, or USB-C port.
  4. Connect the power cord to your second monitor and plug it into an outlet.
  5. Turn on your second monitor. You may need to press the power button on the monitor itself, or use the buttons on your computer to cycle through the video inputs until you see your computer’s display on the second monitor.
  6. Open the Display Settings panel. In Windows, you can do this by right-clicking on the desktop and selecting “Display Settings.” In macOS, you can open the Displays pane in System Preferences.
  7. Click the “Detect” button. This will cause your computer to look for the second monitor. If it’s detected, you’ll see it listed in the Display Settings panel.
  8. Click the “Multiple Displays” drop-down and select “Extend These Displays.” This will cause your computer to use the second monitor as an extension of your desktop.
  9. Click the “Apply” button. Your computer will now use the second monitor as an extension of your desktop.
  10. Arrange your windows. You can now drag windows from your primary monitor to your second monitor. You can also change the resolution and orientation of your second monitor from the Display Settings panel.

And that’s it! You should now have a fully functioning second monitor. Enjoy your extra screen real estate!
