Windows 10: Unable to connect to any Miracast devices

I've got several Miracast devices in my organisation. All Microsoft Wireless display adapters.One month ago one of my machines stopped being able to connect to any of these displays.I press windows +K, select a device, It prompts for a PIN, then just says unable to connect once the pin is entered.I've tried all the troubleshooting steps on here:Troubleshooting Microsoft Wireless Display Adapter

:)

 

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.

Regards.

Thank you for this information. Follow the steps listed below to connect your device:

• If your TV doesn't come with a built-in Miracast support, connect the external adapter into the HDMI port of your TV and power it on.
  
• On your PC, open Settings and tap Devices.
• Under Connected Devices select Add a device.
• You can connect it by opening the Action Center (Windows key + A)
  and select Connect.

If you are still unable to connect, try restarting your PC and the display/adapter. You can also remove the device completely and adding it once again.

If the issue persists, be sure to update your display and network adapter drivers . Else, you may want to consider using a

Microsoft Wireless Display adapter.

Regards.

Hi there Alainpraet!

Step 1: If your TV comes with built-in Miracast support, then turn it On. ...

Step 2: Now on your Windows PC, navigate to Start -> Settings -> Devices -> Connected Devices.

Step 3: Click on 'Add a Device' and wait for the adapter to appear in the list.

Now try to connect.
