However, some users receive a Miracast error message that is not supported by their PC or mobile device. That’s why the miracle mirror doesn’t work.

Here are some possible corrections for errors that are not supported by Miracast on your PC or mobile device. First you need to check if your laptop or desktop computer is indeed compatible with Miracast.

How can I solve problems connecting to Miracast under Windows 10?

1. Network Driver Update

You may need to update your network drivers to correct the Miracast error on your PC or mobile device. To keep your drivers informed, we recommend Driverfix.

This software is the best solution designed to keep your PC in optimal condition without wasting time manually updating drivers. It is a lightweight tool, and the only parts you install on your PC are a driver scanner and a boot loader.

Keep your computer up to date easily and quickly with the best driver update tool.

2. Check if your device is compatible with Miracast.

  1. Press Windows + R, type dxdiag in Run and click OK.
  2. Then click on Save All Information in the DirectX window..
  3. Select a folder to save the text file and press the OK button.
  4. Then press the Windows + Q hotkey.
  5. Type Notepad in the Cortana search field and select to open Notepad.
  6. Then click File > Open and select to open the DxDiag.txt file.
  7. Then scroll down in the DxDiag document to the Miracast details listed under System Information, where it is located: Available with HDCP.
  8. In addition, you should check the compatibility of the network adapters. To do this, connect to PowerShell in Cortana.
  9. Right-click PowerShell and select Run as Administrator.

  11. PowerShell will then display the Ndis version numbers, which must be larger than 6.30.

Pay attention: If you find that PCs do not support Miracast, you will need an adapter to connect the screen wirelessly. Microsoft’s wireless display adapter is probably one of the best for Windows devices.

3. Make sure Wi-Fi is turned on on both devices.

  1. Type Run in Cortana and type Run to open this accessory.
  2. Then type ms-settings:network-wifi into the Open from runtime box and click OK.
  3. Then turn on the Wi-Fi when it is turned off.

Pay attention: Some users claim that their PC or mobile device does not support the Miracast error, although they are sure that their device meets the Miracast mirroring requirements. Another requirement is to enable Wi-Fi on both devices.

4. Select the automatic mode to select the wireless mode

  1.  Right-click the Windows 10 Start button and select Device Manager.
  2. Double-click on the Network Adapters category. Miracle Device Manager

5. Reinstall wireless adapter driver

  1. Right-click the Start button and select Run.
  2. Type devmgmt.msc in Run and click OK.
  3. In Device Manager, expand the Network Adapters category.
