Excellent, I would buy one for my living room pc
...except I can't plug it in.
No TVs with displayport 1.2
No video cards with HDMI 2
Seriously - the common devices which can generate 4k pictures and video easily (4k streaming video being the only other option), which everyone has one of, and you can't connect them to a device which has a selling point of being able to display 4k pictures and video?
TVs with displayport! All those photo editors and architects, video editors and gamers would be able to plug big high detail screens into the PC they use every day. Instead of being restricted to 28", or 30hz
