How to use a Windows Laptop to act as a wireless monitor (for another PC)

If you need a second screen for Windows 10 but don’t have one, it’s possible to use Windows 10. You can use a tablet or Windows laptop as a wireless monitor if you have one.

What you’ll need.

To take advantage of this trick, you will need two Windows 10 computers that support Miracast streaming video standards. This feature is standard on most tablets and laptops, but not all desktops except enware aurora 2019. Miracast may not work if your desktop isn’t built or has a Wi-Fi adapter.

You will need to connect the two machines on the same Wi-Fi network for this to work. Click the Start button and type “Projecting” in the search box. Then click the “Projecting this PC” result. If your settings menu states that “This device does not support receiving Miracast,” you will not be able to use it as a wireless monitor.

Step 1: Configure the Receiving PC.

You must enable the connection before connecting your windows computers. Click the Start button on the PC that you wish to use as a wireless display monitor (which we’ll refer to as the “receiving computer” in this guide), then type “Projecting this PC” into your search box and click the “Projecting this PC” result. You will be taken to the Settings window.

It would be best to choose “Available anywhere” or “Available everywhere on secure networks. This means that strangers can’t accidentally project your screen onto yours via public Wi-Fi networks. You can choose whether Windows will notify you when a device attempts to project onto this computer or only when a new device connects.

If you plan on using this machine frequently as a monitor, choose “First time only.” If you are using the laptop in an insecure or crowded area, turn on the “Require a PIN for pairing.” The last option allows you to prevent projection from occurring when your laptop isn’t plugged in. Monitor projection can drain a lot of battery. Note the PC Name at the bottom of the screen. It’s called “Defiant,” as shown in the screenshot. Switch to your main computer, which you intend to use for the wireless monitor host.

Step 2: Make the Connection.

Now, connect your receiving computer to your main computer and project your screen. To open the Project menu, press Windows on your keyboard. Slide your touchscreen finger to the left and tap “Project” at the bottom of the Action Center menu. Click or tap on the Project menu to connect to a wireless display. The receiver machine you set up in Step One will be listed in the list after a while.

Click it. The screen will say, “[Host] is about connected” (If you have set up a PIN in Step One or requested permission to use this method of connecting, you’ll need to verify the connection here. Your secondary computer will mirror the screen of your primary PC by default. You can modify this to make the secondary monitor extendable or go to Step 3.

Step 3: Set your monitor.

Click the Start button to open the main window. Type “Change display settings” in the search box and click the “Change Display Settings” result. This menu allows you to treat your receiver’s computer as any other standard monitor. To make the best use of your screen, open the “Multiple Displays” dropdown menu and select the “Extend these Displays” option.

On the warning screen, click “Keep changes. Your desktop space will now be expanded to cover both the primary and receiver screens. You can run programs on both the main and second screens simultaneously or extend one program window across both. The receiver’s PC screen’s default position is on the main computer’s right side. You can adjust the screen layout to match your screens by clicking and dragging the menu at the top, then clicking “Apply”.

Your receiver computer is running Windows under the projected desktop. It can be reached by pressing Alt+Tab or sliding your finger inwards from the touchscreen’s left edge. A window labeled “Connect” is the projected monitor on the main computer. You can’t use the receiver computer’s keyboard, mouse, or touchscreen to control it unless you open Windows A (or slide your finger in from to the right) and click the “Allow input” notification.

If you do, you won’t be allowed to access Windows “under” your projected monitor. To stop using your receiver computer as a wireless monitor, press windows. Or slide the Action Center open. Tap “Project” and click or tap “Disconnect.” If the receiver computer is shut down, your wireless monitor will stop working.
