With phone imaging capability quickly outpacing TVs in terms of imaging capabilities, it makes sense that content should be flowing from phones to TVs instead of the contrary. The Microsoft Screen Sharing device is an NFC pad that is connected to the TV via HDMI. It lets anyone who has access to it, share content to the TV. To pair the phone with it, a quick NFC tap suffices, and the idea is that if you have access to the TV, then you should be able to broadcast to it.
Technically speaking, the pad is a Miracast device which receives a Miracast signal from the phone, which is then broadcasted via HDMI wire to the TV. This particular device’s maximum resolution is 1080p, so if you have a 4K TV, it won’t be used at its fullest. Besides personal photos and videos, it is also possible to mirror the smartphone’s screen in general, maybe minus protected (DRM) HD content – we’ll have to double-check on that.
The Screen Sharing for Lumia phones will retail for $79 (79 Euros in Europe…) and should be available this month.
