Solution 1: Check if your device is Miracast-compatible
The first thing you have to do before using Miracast is check if your device supports it.
A Miracast connection is powered by two components, namely your graphics card and network adapter. Check if your network adapter and graphics drivers can support the connection.
Follow these steps to do so:
- To test the graphics drivers, open the Run dialog by pressing the Windows logo key + R on your keyboard.
- Type dxdiag in the text box and click OK or press enter on your keyboard.
- On the DirectX window, click on the button that says “Save all information”.
- Select a folder to save the text file. Click OK.
- Press the Windows logo key + Q.
- Search for Notepad in Cortana.
- In Notepad, click on File > Open.
- Open DxDiag.txt
- In the DxDiag document, you’ll see your system information. Miracast should say “Available, with HDCP.” If not, the connection won’t work on your device.
Solution 2: See that Wi-Fi is enabled on both devices
If you have confirmed that your devices actually support Miracast but you still get the error message, check if both devices have Wi-Fi enabled.
To check if Wi-Fi is enabled on Windows 10, follow this procedure:
- Press the Windows logo key + R to open the Run dialog.
- Type ms-settings:network-wifi in the text box. Press enter or click OK.
- You’ll be led to the Wi-Fi tab of the Network and Internet Settings menu. Click on the toggle to activate Wi-Fi if it is deactivated.
- Also check if Wi-Fi is activated on the other device. How to do so depends on the device in question. On Android and iOS platforms, you can enable Wi-Fi through the Settings app.
