Using Apple TV to mirror from a pc using Widi possible?

Can I use Apple TV as an adapter to mirror the video from my pc using Intel Widi? I heard the 3rd generation Apple TV supports Widi but I can't figure out how to connect. When Intel Widi scans for available adapters it does not see the Apple TV. The Intel Widi help utility says that the TV should be displaying the "To Get Started" screen, but I don't know how to get the TV to do that. I'm trying to run Intel Widi from a PC running Windows 8.0 and I've heard that Windows 8.1 is required, but if so I'm not sure why the Intel Widi program would be pre-installed on my 8.0 machine and running at all up to the stage where it is scanning for available adaptors.
