If your PC is compatible, here are a few fixes you can use to resolve the error – 

Ensure Your PC and the Device are on the Same Wifi Network

Forgetting to connect two devices on the same wireless network is an honest mistake that anyone can make. Hence, ensure that you are connected to the same Wi-Fi,

1. Open Settings on Your Windows PC. Use Windows + I shortcut keys to avoid the longer route.
2. In the settings, open connections and toggle your Wifi On if not already connected.
3. Choose your Wifi network and click on connect.   
4. Move to the display device, and check the Wi-Fi connection. Make sure both devices are connected to the same Wi-Fi network you have chosen on your PC.
5. Make sure both devices are connected on the same and then try to connect.

This should get the job done as it brings both devices to the same level to connect and interact over a network. If the issue persists, move on to the next fix.

Change the Wireless Mode Selection Value

If the device cannot pair using Miracast, it might be due to an error with the mode selection value for your Wi-Fi adapter. The best way to resolve this error is by resetting the value to auto.

Here’s how to do it – 

• Open Run using the Command Windows+R
• In Run, search for devmgmt.msc top open Device Manager. 
• Look for your Wi-Fi adapter in the Device Manager and select properties.
  
• In Properties, navigate to Advanced options.
• In the Advanced options, you will find two columns. Under property, select the wireless mode, and in the corresponding column, open the dropdown to choose the dual-band 802.11/a/b/g.
• Choose it and save the changes.

Once you have done this, try to use the Miracast again. This time it should work fine. In case it still keeps showing this device doesn’t support receiving miracast so you can’t project to it wirelessly, the next fix will help you out!
