Whether you want to use your laptop screen as your sole monitor or you want to use it to extend a display, you can do plenty with it.

However, the process might not be as easy as you would assume. After all, the majority of laptops on the market only have an output port for displaying what is on the screen to an external device.

Therefore, simply grabbing an HDMI, DVI, or Display Port cable and running it from another PC to your laptop isn’t going to work to use your laptop as a monitor.

That being said, there are certain ways you can get it to work and not all of them are going to be overly complicated. Below, we will be going over different ways you can go about doing it.

How To Turn Your Laptop Into A Monitor:

Method 1: Use Miracast (For Windows)

Luckily, Microsoft built-in Miracast to the Windows operating system. Because of this, you can use Miracast to effectively use your laptop’s screen as a mirrored monitor, this will depend on what kind of laptop you are using. However, you do have to set it up before you can get it working.

If You Want To Use Your Laptop As A Monitor

  • Go To “Search” > Type in “Projection Settings” > Change drop-down menu to “OK” > Setup PIN for pairing

If You Want To Use Your PC Display On Your Laptop’s Screen

  • Go To “Search” > Type in “Connect” > Click on Laptop You Want To Use With Miracast > Accept the Connection On Your Laptop (enter the PIN)

If You Want To Use Your Laptop As A Second Display/Monitor

  • Type in “Display Settings” in Search > Choose “Extend Desktop To This Display” > Configure the Displays As You Wish

Once you do this, you should be able to get started with projecting either your Android phone, tablet, or even another compatible computer to your screen.

Keep in mind, not every device is going to be compatible with Miracast just because it is built into the operating system. The hardware needs to support it.

It requires a display adapter that supports Windows Display Driver Model 1.3 and a Wi-Fi adapter that is capable of supporting Wi-Fi Direct. If your laptop has this, you will be able to utilize the Miracast functionality in order to use your laptop as a monitor.
