Hello,

  I have 2 Surface Pro 3's with Windows 8.1 on both.  I also have the new Microsoft Wireless Display Adapter plugged into my TV.

  1 Surface Pro 3 works fine on the Wireless Display Adapter, and 1 doesn't.

  For the one that doesn't, I can connect, the screen on the TV says "Connecting to [computer name]", then the TV screen goes black for about 30 seconds.  On the surface, I click Devices, Project, Duplicate, and then I select the MicrosoftDisplayAdapter and the screen blinks on the Surface for 2 seconds and it appears to lower it's resolution.  Then maybe 30 seconds later it goes back to the normal resolution.

I don't have any firewall, antivirus, or other utilities installed.  There are no errors in the event log.

There are no real troubleshooting steps online I found to help figure out the issue.  Does anyone know how to fix this?

Thanks.

I found in Device Manager, there is a device called IWDAUD_Device_02 that it says Driver Unavailable for. I think this is the Intel WiDi driver, but why is it missing from Windows 8.1 / Surface Pro 3.

Does anyone know where to get this driver?

Thanks.

On the working Surface 3, this is listed as Intel Widi Audio Device under the Sound, Video and game Controllers group in Device Manager.

Hi Ryan_Ha,

It seems that there is something wrong with the Intel driver .We can make it update automatically or manually download the driver from the Intel download center for the device and install it for the device from the device manager.

1.To make it update automatically ,we can uninstall it and then restart the machine to make it update automatically.
2.To manually install the driver :Download the driver from the Intel website and then right click the devie and choose "Update Driver software",choose "Browse my computer for driver software",navigate to the driver you have downloaded .

Go to https://www.microsoft.com/en-us/download/details.aspx?id=38826 and download the Surface Pro 3 March 2015.msi (not the zip file). Don't run it yet.   Go into device manager and expand the Intel Display Adapter and uninstall the device. Don't remove the driver at this point. Shut down and start up your SP3. The driver should reinstall. Try Miracast again. If still broken, go back to device manager and uninstall the display adapter and this time when prompted, delete the driver files. Restart. Run the msi installer. Restart. Please report back.

The generic Intel drivers may cause more issues with Connected Standby, etc. and are not recommended for use with the SP3.   I'm not sure why you posted the recommendation to NOT use the specific customized Surface drivers.  

Thanks everyone, I was looking for the drivers and the firmware but couldn't find them before you posted.  I ended up just restoring my Surface 3 and it works now, so I'm assuming it would have been a driver issue then that got changed or something.

Thanks for everyone's help.
