Default [Q] Miracast (or similar) to pc?

Is it possible in anyway to use something like miracast (or any way of screen mirroring) to a media PC.

Basically I have a media PC running windows 8.1 with XBMC on it in my living room and I wanted to be able to connect my android to it to mirror the screen. Although I have not come across anything like this I am surprised that if a tiny little dongle into the back of a TV can manage this that my PC can't even if I have to buy some kind of adapter.

I hope there is some sort of solution.
