Windows claims that my device doesn't support Miracast

I just bought a Microsoft Wireless Display adapter and my Windows 10 machine is claiming that my device doesn't support Miracast. Using the guide here, I confirmed that I have NdisVersion 6.4 on my Wifi card and that my display driver has WDDM 2.0.

My hardware:

• Nvidia GTX 770M ruing the latest stable driver
• Intel i7 4710MQ @ 2.5GHz
• Intel Duel Band AC 7260 updated to the latest driver

As far as I'm aware, this is all that's required to use Miracast, yet when I go to the action center and select "coect", Windows tells me that "Your device doesn't support Miracast, so it can't be project wirelessly". Am I missing a requirement for Miracast or has Windows gone crazy?
