Miracast is a wireless technology that your Windows 10 devices can use to project their screens to TVs, projectors, displays and streaming media players that support this technology. However, if your TV or monitor doesn't offer Miracast, you can purchase a Miracast dongle like the Microsoft Wireless Display Adapter and use it to project wirelessly to any display with an HDMI port. Here's how to wirelessly project from a Windows 10 computer or device with support for Miracast, to any display, using the Miracast technology:
What do you need for the wireless projection?
Before you move forward with this tutorial, double check that you have the following items available:
- A TV or monitor with built-in Miracast support or...
- A miracast dongle like the Microsoft Wireless Display Adapter. The dongle needs to be plugged into a TV or monitor with both an HDMI port and a powered USB port. The TV/monitor should not be more than 7 meters or 23 feet away from your Windows 10 computer or device. If the display doesn't have a powered USB port, you can use a USB smartphone charger and plug in your Microsoft Wireless Display Adapter into it, so that it gets the power it needs.
- A Miracast enabled device with Windows 10 like the Surface Pro 3, Surface Pro 4 or the Surface Book. If your computer came with Windows 10 installed, it should support Miracast by default. If you've upgraded an old PC to Windows 10, it may or may not support Miracast. You must check its official hardware specifications to ensure that it has support for the Miracast technology.
If you have everything on this list, then go ahead and follow these steps:
Step 1: Set up the TV or the display that you want to connect to
If you have a TV or a display with Miracast support, then you need to make sure that it is turned on and that Miracast wireless connections are not turned off. If the Miracast display that you are using is turned on and working, move to step 2 in this guide.
If you are using a Miracast dongle like the Microsoft Wireless Display Adapter , you need a TV or a monitor with an HDMI port and a USB port. The USB port must receive power from the display or the Miracast adapter won't work. Plug the Microsoft Wireless Display Adapter into the HDMI and USB ports on the display where you want to project. If the USB port on the TV or the monitor is not powered or it's missing, then you need a power source for the Miracast dongle. As mentioned earlier, you can use the USB charger of any smartphone to power the dongle, just like in the picture below.
Then, use the remote or the configuration menus of the display and set its input to the HDMI port where you plugged in the Miracast adapter. If everything worked well, you will see an image like the one below, saying: "MicrosoftDisplayAdapter_EF Ready to connect". If you are using another Miracast adapter, from another manufacturer, then, the message on the screen will be different.
If you don't see this message on the screen, it means that the USB port doesn't supply any power to the adapter.
Step 2: Connect to the Miracast-enabled screen from your Windows 10 device
Now you should go to your Windows 10 computer or device with Miracast support and connect to the Miracast display or the Miracast adapter, so that you can use it to project wirelessly.
In Windows 10, there are two ways to initiate the connection through Miracast:
The first is to click or tap the Notifications icon on the Windows 10 taskbar, to bring up the Action Center. On a device with touch, you can also flick from the right side of the screen, to bring up the Action Center. In the Action Center , click or tap Project.
The project side pane opens. There, click or tap "Connect to a wireless display ".
Windows 10 starts searching for wireless display and audio devices. Once it detects your Miracast display or your Miracast adapter, click or tap on it. If you are using a Microsoft Wireless Display Adapter, it should detect a device named MicrosoftDisplayAdapter_EF. Click or tap on it and wait for Windows 10 to connect to it.
A second way to connect to the Miracast-enabled display, is to open the Settings app. There, go to System and then to Display. In the " Customize your display " section there is a link that says: "Connect to a wireless display ". Click or tap on it and it brings up the list of Miracast devices that Windows 10 detects.
Click on the Miracast-enable devices that you want to connect to and you are done.
Step 3: Project wirelessly to the TV or the display that you want to use
You can change the way you project to the Miracast-enabled display at any time. Immediately after you connect to it, you can click or tap "Change projection mode ".
This brings-up the Project pane where you can set how you want to project the image on the Miracast-enabled display. You can get to the same pane by pressing Windows + P on your keyboard or by pressing the Notifications icon on the taskbar and then on Project.
Step 4: Disconnect from the Miracast-enabled display
When you are done projecting to the Miracast-enabled display, you should disconnect from it. There are several ways to do that. One way is to open the Settings app and click or tap System , followed by Display. There, click or tap on the link that says: "Connect to a wireless display". This brings up the Connect pane where you should press Disconnect.
Another way is to press Windows + P on your keyboard or to click or tap the Notifications icon on the taskbar and then on Project. Choose Disconnect and Windows 10 disconnects from the Miracast-enabled display.
As you can see, projecting wirelessly in Windows 10 using TVs or displays with Miracast support or Miracast dongles like the Microsoft Wireless Display Adapter, is relatively easy. Once the initial setup is done, projecting is as easy as with a normal projector. If you have any questions about this procedure, don't hesitate to share them using the comments form below.
