When a resolution of 4K caused heart palpitations, but now is no longer something unusual. The only trouble is, that the transfer of the image still needs the appropriate interface - @ 30 Hz, you can use HDMI 1.4, and in 60 Hz is already HDMI 2.0. When such a connector should be expected in the case of Intel Platforms?
It turns out, that will not soon - informally known, that the HDMI 2.0 appears only 2017 year, on the occasion of the release of processors generation Cannonlake. Until that time, still have to be content with HDMI 1.4 и DisplayPort 1.2 (the changes do not bring in this year's model Kaby Lake-t. it is. de facto updated Skylake system).
by the way, should be added, that support for HDMI 2.0 now offer Nvidia graphics cards from generation Maxwell 2.0 (GeForce GTX 900), while at any moment will be new generation of Polaris Radeony.
In the case of Intel Platforms, you can still look for original solutions to design manufacturers (eg, Gigabyte GA-Z170X-Gaming G1) or choose an external adapter DisplayPort connector 1.2 и HDMI 2.0.
