Microsoft’s new Wireless Display app lets you cast your Windows or Android screen to an Xbox One, and it works with PC games OnMSFT.com: "One the blue cast screen is loaded, you can connect to it just like you would any other Miracast display, by going into the display menu (via the Win P command) and select XBOXONE. If you intend to control the PC from the Xbox such as for playing games, make sure to tick the box to enable keyboard and mouse input from the Xbox."
