Projecting to a wireless display with Miracast

Miracast is a wireless technology your PC can use to project your screen to TVs, projectors and streaming media players that also support Miracast. You can use this to share what you’re doing on your PC, present a slide show or even play your favourite game on a larger screen.

Getting your devices ready

If your PC came with Windows 8.1 or Windows RT 8.1 and your wireless display supports Miracast, you’re ready to add the wireless display to your PC to complete the connection and start projecting.

However, if you've upgraded your PC from an older version of Windows, you'll need to make sure your PC supports Miracast and is ready to project. Also, if the display you're going to project to doesn’t support Miracast, you’ll need to set up the display by adding an extra piece of hardware to it before you can start projecting.

To prepare an upgraded PC to project

To help avoid problems with projecting, make sure your PC supports Miracast and that it has the most current drivers.

Checking whether your PC supports Miracast

  1. Swipe in from the right edge of the screen, and then tap Devices.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Devices.)

  2. Tap or click Project. If you can see Add a wireless display, your PC supports Miracast.

    If your PC doesn’t support Miracast, you can try to project with a wired connection. For more info, see Connecting a second monitor or projector.

Getting the current drivers for your PC

A driver is software that a device uses to work with your PC. If you've upgraded your PC from an older version of Windows, you should get the latest drivers available for your PC. There are two ways of getting them.

To set up a display that doesn’t already support Miracast

If the device you're projecting to doesn’t support Miracast, then you’ll need a Miracast adapter (sometimes also called a dongle) that plugs into an HDMI port on your display device. The adapter lets your PC communicate wirelessly with the display device.

A variety of manufacturers offer Miracast adapters, such as the ActiontecScreenBeam Pro Wireless Display Receiver and the NetGearPush2TV (PTV3000) Wireless Display Adapter. Follow the manufacturer’s instructions to connect the adapter.

You should also update the firmware on your adapter by going to the Support section of the manufacturer's website, searching for your specific device and following their instructions to download and install that firmware. You can also check the Windows Store to see if there’s an app that will update the firmware on your adapter.

Adding the display to complete the connection

With your PC and display ready to project, you need to add the wireless display to your PC. Both devices need to be within range, which usually means that they're in the same room.

To add a wireless display to your PC

  1. Swipe in from the right edge of the screen, and then tap Devices.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Devices.)

  2. Tap or click Project, then tap or click Add a wireless display.

  3. Choose the wireless display from the list of devices found, then follow the instructions on the screen.

Projecting your screen to a wireless display

After you've added the wireless display to your PC, you can project your screen to it and change what you see on each screen.

To project your screen

  1. Swipe in from the right edge of the screen, and then tap Devices.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Devices.)

  2. Tap or click Project, then tap or click the wireless display you want.

To choose what you see on each screen

  1. Swipe in from the right edge of the screen, and then tap Devices.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Devices.)

  2. Tap or click Project, then choose one of these options:

    • PC screen only. You'll see everything on your PC. (When you're connected to a wireless projector, this option changes to Disconnect.)

    • Duplicate. You'll see the same things on both screens.

    • Extend. You'll see everything spread over both screens and you can drag and move items between the two.

    • Second screen only. You'll see everything on the connected screen. Your other screen will be blank.

Disconnecting from a wireless display

If you move your PC beyond the range of the wireless display (such as to another room), or if you make your PC sleep or hibernate, the two devices will disconnect. You can also disconnect the wireless display manually.

  1. Swipe in from the right edge of the screen, and then tap Devices.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Devices.)

  2. Tap or click Project, then tap or click Disconnect.

Fixing problems

You can solve many problems by installing the latest drivers for your PC and the latest firmware for your wireless display or Miracast adapter. For more info about installing drivers on your PC, see Downloading and installing drivers. To update firmware on your wireless display or adapter, go to the Support section of the manufacturer's website, search for your specific device and follow their instructions to download and install that firmware. You can also check the Windows Store to see if there’s an app from the manufacturer of your wireless display or Miracast adapter that updates firmware.

Here are a few more steps to try if you continue to experience problems.
