It's easy to snag a Miracast-capable device if you're willing to shop for a brand new TV or a set-top box. but it's much tougher if Miracast is the only thing you're looking for. Minimalists will be happy, then, that Panasonic just released a dedicated adapter for the job. Plug the very utilitarian-looking brick into an HDMI jack and you can wirelessly stream HD-grade video from any supporting device on the same WiFi network; Panasonic would naturally prefer that it's the company's new Eluga X smartphone. The adapter is so far only available in Japan for an estimated and rather steep ¥8,980 ($95), although we're hoping that it eventually crosses the Pacific at a price that befits the narrow focus.
