How to Use Your Laptop as a PC Monitor

You can use your laptop as a PC monitor in a pinch, and it’s not as difficult as you might think. Here’s how to do it.

First, you’ll need to connect your laptop to your PC. You can do this with a VGA cable, an HDMI cable, or a DVI cable. If your laptop has a DisplayPort, you can also use a DisplayPort-to-HDMI adapter. Once you’ve connected the two devices, you’ll need to configure your PC to use your laptop as a second monitor.

To do this, open the Control Panel and go to Display. Under the “Settings” tab, click “Detect.” This will cause your PC to search for any connected displays. Once it finds your laptop, select it and click “OK.”

Now, you’ll need to choose how you want your displays to be arranged. You can either extend your desktop across both displays, or you can mirror your desktop on both displays. If you want to use your laptop as a primary monitor, you’ll probably want to extend your desktop. This will give you the most screen real estate to work with.

If you want to use your laptop as a secondary monitor, you can choose to mirror your desktop. This will show the same content on both displays. You can also choose to have your laptop display only a portion of your desktop. To do this, select the “Customize” option under the “Settings” tab.

Once you’ve chosen how you want your displays to be arranged, click “OK” to save your changes. Your PC should now be using your laptop as a second monitor. You can now move your mouse cursor between the two displays, and your laptop will act just like a second monitor.

If you want to disconnect your laptop from your PC, simply unplug the cable that’s connecting the two devices. Your PC will automatically revert back to using its built-in display.
