Microsoft Wireless Display Adapter
Some weeks ago I was in the US for a couple of days, I took advantage of that and visited the Microsoft Store to get a Microsoft Band which was unfortunately out of stock. But I found another great gadget, which as far as I know is only available in the US and Canada, called the Microsoft Wireless Display Adapter. The Microsoft Wireless Display Adapter is basically a Miracast receiver, which you can use to project your Windows, Windows Phone or Android display wireless to another screen or projector.
The adapter has a HDMI port for the display signal and a USB port to power the adapter. You plug them in to your TV and after the adapter finished booting you can start connecting your Wireless Display. The Wireless Display Adapter does not only stream the video, it also allows you to stream audio.
This is perfect not only at home, but also during meetings or presentations. With the Windows Store App for the Wireless Display Adapter you can also configure some settings like name or security for the adapter.
