How to support a resolution of 3840 x 2160?

TigerDirect has a Seiki 4k TV at $1,500. They mention that it can be used as a large monitor and it has a refresh rate of 120Hz.

What I can't figure out is how one would supply video to this thing over it's available connections. It only has HDMI and VGA. Obviously VGS is not even a starter.

HDMI 1.3 specification is for up to 2560x1200 at 60Hz over a single link. I can't find any higher resolutions.

Does this mean that one can stick two HDMI cables in a graphics cards and "somehow" send the output over both links if one should wish to se this as a monitor?

What kind of graphics card would do this? Or again, would one need two different cards?

So many questions.

Oh, here is the link to the 50-inch 4K monitor.

    HDMI 1.4 :)

    DP 1.2

    also, I'm pretty sure any decent graphic card can handle 4K, but if you're looking to game at 60+fps, you should consider at least two-three of them :)
  2. I don't know of any gpu that has hdmi 1.4 yet. For the price of that tv you could get three 2560x1440 monitors in eyefinity and still have a couple hundred left over.

    HD7970 has an both HDMI 1.4 and DP 1.2 - that thing is very capable at feeding the display 4K /x 60 Hz - over the DP/. well, the problem with 4K gaming is, that you'll get 30 FPS on average (which kinda sucks). Also more than 4GB VRAM should be recommended...

    Now, the Titan would be viable choice - HDMI 1.4a + DP 1.2 support, 6GB VRAM and a lot horsepower :)

    But as long you're not gaming, those cards would be a waste :)

    Also, on a side note - every GF6xx should have by default a DP 1.2 and HDMI 1.4a support, so it is capable of displaying 4K... Sorry, I don't know about much AMD side :)
  4. Well TIL. I assumed the reason for needing a dp/dldvi cable for 2560x1440 was because my gpu hdmi port didn't support it. Must have been the monitor's hdmi port instead.

    Seems my Radeon HD 7950 has what it needs...
