Supposedly any nvidia card with PureVideo5 can do HDMI 1.4a and drive
a 4k display over it.

Someone claims to have tried with a gtx660 ti card and it worked for
them in windows:

I believe the refresh rate is limited to 30Hz at 3840x2160 resolution
over HDMI 1.4a though.  Higher refresh rate would require display port
1.2 or higher, and I haven't seen any TVs with that.

No idea if the linux drivers support doing that yet.
