Like other Miracast HDMI dongles, Microsoft's Wireless Display Adapter lets you easily mirror the screen of your Windows (or Android) devices on monitors, TVs and projectors -- anything with an HDMI input, really. Redmond's reasonably priced dongle has been kicking around for roughly 18 months now though, meaning its high time for an updated model. Microsoft's next-gen Wireless Display Adapter improves on its predecessor in two ways. For starters, the HDMI dongle itself has been almost halved in length, though it still draws power from a tethered USB cable. More importantly, the new version improves responsiveness (aka latency), so your poorly framed smartphone video should pop up on your living room TV that bit quicker.
