At the Microsoft BUILD conference in San Francisco earlier this month, Microsoft unveiled its next software update to the line of Windows Phone 8 devices, Windows Phone 8.1. With this software update that is currently available for Windows Phone developers, we are now able to mirror our phone's display on a PC with a software from Microsoft, Project My Screen App. As of now, your Windows Phone must be connected to your PC using a USB cable and there are no support for wireless mirroring capability at the moment.
