Using Miracast Wirelessly

1
Make sure your screen receiver is set up and connected to Wi-Fi. Your receiver display must be connected to the same wireless network as your computer to use Miracast's screen mirroring feature.
- If you're not sure how to connect your computer to a wireless network, you can look it up for Windows 10, Windows 8 or Windows 7 here.
- Setting up your projector, monitor or TV will vary from device to device. You can refer to your display's manual for specific instructions.

Open your computer's Start menu. Find and click the Windows icon in the lower-left corner of your computer's desktop to open the Start menu.

Method 2 of 2:

Using an HDMI Cable

1
Get an HDMI cable. HDMI helps you transmit and project your computer's uncompressed audio and video output in high-definition.
- If you don't already have an HDMI cable, you can buy one online or at an electronics store.
- Most computers and displays come with a built-in HDMI port. If one of your devices doesn't have an HDMI port, you can purchase an adapter, or use a different cable such as Mini DisplayPort to HDMI.
2
Plug one end of the cable into an HDMI port on your computer. You can usually find an HDMI port on the side or on the back of a laptop or desktop computer.
3
Plug the other end of the cable into your display. Find an HDMI port on your TV, monitor or projector, and plug the other end of the cable into here.
- Both ends of the HDMI cable look the same. You can plug either end into your TV, monitor or projector.
4
Switch your TV or projector to the HDMI input. Once the HDMI input is selected on your display, your computer's screen will be automatically mirrored on your TV or projector.
- If your display has more than one HDMI port, you will need to select the correct input port here.
- Setting up your display's input will vary depending on your TV or projector. You can refer to your display's manual for specific instructions.
