If you turn on your phone’s NFC connection and tap it to the top of the coaster, it authenticates it to the device and allows it to connect. But what’s unique about it is the detachable, NFC “coaster” that sits atop it. It’s a round, white, hockey puck, with an HDMI connection and power cord in the back. There’s just enough latency to be annoying.Ĭompared to the Wireless Display Adapter, the HD-10 seems a bit over-engineered: nifty, but unnecessary. That extra hop those devices require, however, when streaming video from the Internet-from Netflix, say, through your phone to the Miracast device-seems to make all the difference. With Microsoft’s solutions, any data they receive is fed via your phones or tablets-fine for projecting photos or documents. The difference is in the technology: The Chromecast connects to your phone or tablet, then downloads a stream from Netflix by itself. That sounds like a superior solution compared to Chromecast, Google’s $35 streaming stick, which a user controls via his or her smartphone.

(Note that you don’t need a Windows Phone or tablet to connect to either device. Microsoft’s solutions, however, use Miracast, which taps a direct Wi-Fi connection between the two devices, rather than an intermediary router. Most PCs solve this problem via an HDMI output that allows the TV to act as a second display. They’re two different approaches to the same problem: how to project your phone or tablet screen to a TV. The other was independently developed at Microsoft, before the merger brought the two together. The first, to connect smartphones, was developed at Nokia. In the past few weeks, Microsoft announced two very different ways to bridge the last few feet between your connected devices and your television: the $100 Microsoft Screen Sharing for Lumia Phones HD-10, and the $60 Wireless Display Adapter. But the Miracast technology Microsoft included in devices that connect your phone and PC to your TV doesn’t quite hold up under heavy load. Most wireless technology is fast enough these days to deliver not just one, but several high-definition video streams.
