How to Use a Windows Laptop as a Wireless Monitor 2023


Wireless Monitor For PC You’d like a secondary screen to increase your productivity in Windows 10, but you don’t have another monitor handy. If you have a recent Windows laptop or tablet, you can use it as a wireless monitor.

What You’ll Need

To take advantage of this trick, you’ll need two Windows 10 machines that support the Miracast streaming video standard. Most newer laptops and tablets have this built-in, as do some desktops. However, if you’ve built your desktop or have one that doesn’t have a WiFi adapter, it might not support Miracast. You’ll need to connect both machines to the same local WiFi network to make this work.

If you’re unsure whether your Windows laptop or tablet supports Miracast, click the Start button, type “Projecting” into the search box, and then click the “Projecting to this PC” result. If the settings menu says, “This device doesn’t support receiving Miracast,” then you won’t be able to use it as a wireless monitor.

Step One: Set Up The Receiving PC

Before you connect your two Windows machines, you’ll need to enable the connection. On the PC you want to use as a wireless monitor (which we’ll call the “receiving PC” for this guide), click the Start button, type “Projecting to this PC” into the search box, and then click the “Projecting to this PC” result.

This takes you to a Settings window. On the first dropdown menu, you need to select “Available everywhere” or “Available everywhere on secure networks.” The second option means strangers won’t be able to accidentally project their screen to yours on a public WiFi network.

On the second dropdown menu, you can control whether Windows notifies you every time a device tries to project to this PC or only the first time a new device connects. Choose “First time only” if you frequently use this machine as a monitor.

Turn on the “Require PIN for pairing” option if you’re using the machine in a crowded or insecure space. And the final option lets you prevent projection from happening when the laptop is not plugged in. Monitor projection can be very battery-consuming.

Make a note of the PC Name at the bottom of the screen. (It’s “Defiant” in the screenshot above.) Now switch to the main PC—the one you want to use as the host for the wireless monitor.

Step Two: Establish The Connection

You can project your screen from the central computer with your receiving PC ready.

On your keyboard, press Windows+P to open the Project menu. On a touchscreen, slide your finger in from the left and tap “Project” at the bottom of the Action Center menu.

On the Project menu, click or tap the “Connect to a wireless display” link.

After a moment, the receiver machine you set up in Step One will appear in the list. Click it.

The receiver machine will display a screen that says, “[Host] is about to connect.” (If you’ve set up a PIN or a permission request in Step One, you’ll need to verify the connection here.)

By default, on the first connection, your secondary machine will merely mirror what’s on your primary PC’s screen. To tweak this and use the secondary PC as a whole extended monitor, proceed to Step Three.

Step Three: Adjust Your Monitor

Click the Start button on your main PC, type “Change display settings” into the search box, and then select the “Change Display Settings” result.

You can treat your receiver PC on this menu as any standard monitor. For ideal screen use, open the “Multiple Displays” dropdown menu and choose the “Extend these displays” option. Click “Keep changes” on the warning that appears.

Now your desktop space is expanded across the screens of both your primary and receiver PCs. You can run programs over on the second and the main screens simultaneously or extend a single program window across both of them.

The receiver PC screen will default be positioned to the main PC’s right. If this doesn’t match the physical configuration of your screens, you can click and drag the screens around at the top of this menu and then click the “Apply” button.

And, of course, your receiver PC is still running its instance of Windows underneath the projected desktop. You can reach it by pressing Alt+Tab or sliding your finger in from the left edge of the touchscreen. The projected monitor from the main PC is a window labeled “Connect.”

You won’t be able to use the mouse, keyboard, or touchscreen on the receiver PC to control the main PC unless you open the Action Center (Windows+A or slide your finger in from the right) and click the “Allow Input” notification. If you do, you won’t be able to reach Windows “under” the projected monitor.

To stop using your receiver PC as a wireless monitor, press Windows+P or slide the Action Center open and tap “Project.” Click or tap “Disconnect” at the top of the menu. Your wireless monitor will also stop working if the receiver PC shuts down.
