Windows 10: Miracast Stopped Working For No Reason

I want to use my laptop as a second monitor, and using Miracast it worked. But after I ended the connection, I couldn't find my laptop on my PC. I checked on the Connect app, and both worked, but I couldn't connect to or find my laptop. I've tried removing my laptop from my devices and tried to reconnect, but it didn't work.

Someone please help me.

Miracast stopped working

Hi Gina,

Issues with Miracast are usually resolved by installing the latest drivers for your PC and the latest firmware for your wireless display or Miracast adapter. To update firmware on your wireless display or adapter, go to the Support section of the manufacturer's
website, search on 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.

And, we would also suggest that you try performing the suggested troubleshooting steps on this thread and check if it works for you.

Regards.

 

Does Miracast support 4K?

Hello,

We suggest that you check with the manufacturer of the 4k display device that you are using if it is certified to work with Miracast. If your display device is certified to work with Miracast, then check if your PC device supports Miracast. You may do so
by following the steps below:

• Click Start, then go to Settings >
  Projecting to this PC.
• Check if your device supports Miracast.

Miracast not Working

Hi Albert,

There's a possibility that an automatic may have occurred or there could be changes performed on your computer that have caused your Miracast to stop working. The device driver currently installed may no longer be compatible.

For us to isolate and address this problem, we suggest updating the Miracast drivers. Please see
