NVidia clearly states you cannot do UHD with a 6 or 7 series video card without using the Displayport.

Uh, there is no adapter. If your card does not have a display port, then it cannot do UHD.  Putting an adapter on an HDMI port so you can plug into the Displayport of the television is not going to work.

The reason they require the Displayport has to do with bandwidth.  HDMI does not have the bandwidth to support UDH resolutions.

I would just like to report that I am running a GTX760 and today plugged it into a 4k 58" TV and have the same issues as PapaFox.

Flashing white screen and AH will not run.

I too might need to look at a bigger card.

You will need a 500+ dollar graphics card to play any recent game in 4k at playable framerates.

GTX760 has a display port but my tv does not :( There is a display port adapter but it reduces the signal back to HDMI 1.4 :(

I read somewhere yesterday that Sony and Samsung have an accessory box that spits out HDMI 2.0 for use with certain older tv's that are only HDMI 1.4 
In terms of Display Port TV's only one available is the Panasonic AX800.

Yes looking that way .. I think at this stage its still better to stick to 1080 :)
The NVidea 970/980 series have HMDI 2.0, my older 760 has display port but finding a tv with display port is tough.

Its a costly exercise which ever way one turns :(
