Dual link DVI can do 2560x1600 @ 60Hz, which means it could do 4k @ 30Hz.

It would have to be an active adapter.  As far as I can tell, no such
adapter exists (I think some used to, but no longer do).  I can't even
find a dual link dvi to display port adapter.  If such a thing existed,
you would be able to convert that to HDMI 1.4 afterwards (although you
would be using two active adapters at once).  But no such luck either
it seems.

The KVM should just have to pass the monitor's EDID data through and
the video signal the other way.

That would be single link only, and depending on what the nvidia does,
that may or may not include higher link speeds.  If they recognize the
HDMI adapter being plugged in then they might choose to support HDMI 1.3+
link speeds, in which case it could do 4k resolution.  If they don't,
then it will just support 1920x1200.  I suspect most nvidia cards capable
of HDMI 1.3+ would actually have an HDMI port already on the card.

Which nvidia card do you have?
