The only existing technology you definitely can use for this new specification is the TV. Your current flat-screen TV is probably compliant with HDMI 1.x, which is guaranteed to work with the new specification.
But not all phones will work with this new technology. Some mobile devices come with a built-in HDMI chip to allow the outputting of their displays to TVs, but not all phones or tablets have it — and the ones with HDMI usually have a mini-HDMI port that looks like this:
On the other hand, if your device has an HDMI output as well as a USB Type-C port, then you’re in luck. All you’ll have to wait for is the release of the brand new USB-C-to-HDMI cable. (No release date yet since the cables still need to be tested for compliance, but it shouldn’t be too long given USB Type-C’s rapid rate of adoption.)
It shouldn’t be too long before newer phones, tablets, and laptops are designed and released with this new standard in mind. HDMI Licensing says, “There is currently demand for this technology so new products incorporating this may be introduced at CES 2017 and launching early next year.”
