Windows 10 includes a screen mirroring feature called “Project to this PC,” which uses the Miracast standard to wirelessly project the contents of the screen to another computer (or supported devices like smart TVs and streaming boxes) on the same local network.
This is a great feature that can be useful in a variety of situations. For example, if you have to work from home and need a dual-monitor setup to increase productivity but don’t have a second monitor. Or, for example, you want to connect a laptop to your smart TV (from Sony, Samsung, etc.) to watch videos or play games, but you don’t have the necessary physical connection – to name a few examples. It’s a useful feature that’s also simple to use.
Whatever the reason, you can use the “Project to this PC” settings and the “Connect” app to transform a Windows 10 computer into a wireless display without the need for additional hardware or software.
We’ll walk you through the steps in this Windows 10 guide to using another device as a wireless display.
How to Turn Your Windows 10 PC into a Miracast-Capable Wireless Display
If you want to use screen mirroring on Windows 10, you’ll need a source and destination device that support Miracast technology and are connected to the same network, as well as some specific steps.
- Open the action center. (Click the speech bubble icon is located in the lower right corner of the screen.)
Tip: You can use the Windows key + A keyboard shortcut, or you can click the Action Center icon in the far right of the taskbar.
- Click Connect option.
- Click Projecting to this PC. (A settings window will be displayed.)
- Select “Available Everywhere” or “Available everywhere on secure networks” from the top pulldown menu.
- Select “First time only” or “Every time a connection is requested” under “Ask to project to this PC.” (Unless you’re really worried about a rogue thief grabbing your phone and projecting to your computer without your permission, I recommend selecting “First time only.”)
I also suggest leaving “Require PIN for pairing” unchecked because you must grant permission on the receiving computer anyway. You can also specify whether your PC should only receive projection requests when it is plugged in.
- When Windows 10 alerts you that another device wants to project to your computer, click Yes.
The Windows Connect app will open in a new window. The window can be dragged, resized, or maximized. Also, if the sending device is a Windows 10 PC and allows it, you can remotely control the sender using the keyboard and mouse on the receiving computer.
How to use PC as a secondary wireless display
If you’re using Windows 10, here’s how to broadcast your screen from the sending device. (The wireless display menus on Android devices differ.)
- Open the action center.
- Click Connect. A list of available receiving devices appears, and your other computer should be on it.
- Click the device you want to project the screen. You may have to wait a minute or longer for the devices to pair. If the connection fails, you’ll need to try again.
- Toggle “Allow input” to “on” if you want to let the receiving device control your PC with its keyboard and mouse.
- Click “Change projection mode” and select “Extend”, If you want to use the wireless display as a second desktop rather than a mirror of your current desktop, select it from the menu that appears.
- When you want to end your connection, click Disconnect.
