I have been looking myself. I haven't been able to find anything to do it. I don't have a 4k tv yet but was planning on getting one when this was possible. The closest thing I have found is this

http://www.amazon.com/dp/B00COEBCXY/...9Z8HC13P&psc=1

The amazon listing claims that it will do this (hdmi 2.0 4k@60Hz) however the belkin website doesn't mention this at all. This adapter has also been on amazon since May of 2013 so unless they have changed the hardware without changing the model number, I'm not sure if it will work.

A standard DP to HDMI 1.4 cable will work, technically, as HDMI 2.0 did not change the cable, only the transceivers. I am however unsure as to if there are protocol or driver changes needed to make it function.

I emailed them to find out but these are likely the guys who would do it:

http://www.paradetech.com/

They are the ones who make the actual adapter in the accel active DP 1.1 -> HDMI 1.4 adapters. I actually found out accel was coming out with said adapter months before they actually released it after hitting these guys up when I found they actually made a chip that actually does the conversion.

Wow I got an amazingly fast response from the same guy I talked to last time.

He said they are indeed coming out with a DP 1.2 -> HDMI 2.0 adapter for dongles/motherboards and they are working with Bizlink/accel again and they (adapters via bizlink/accel) should be available Q2 2015 or possibly Q1 2015 so sometime next year.

Their DP 1.1 -> HDMI 1.4 adapters work great and have been extremely reliable for me so I am sure these new ones will work good as well.
h4nc0 and infodroid like this.

I posted this in another thread, but I feel it bears repeating here.

Can't post links yet, but check out the VESA press release for CES:

Quote:
DP-to-HDMI 2.0 Legacy Adapter – DisplayPort is designed to provide backward compatibility for existing display types. This video adapter converts DisplayPort 1.2
to HDMI 2.0, driving a 4K@60Hz monitor with full 24 bit video.
That should be what we want. I haven't been able to find any more info though, as in release date or price.

Very cool but, I am getting 2160p @ 60hz out of a GTX750ti 2gb via HDMI right now....It's only HDMI 1.4 but, with a PC connected using Windows Media Center I can get it...

Yes, but according to what I read about that, the only way to get 4k@60hz on a HDMI 1.4 bandwidth was to compress the color space, which is far from ideal.

The only way to get uncompromised 4k@60 on a graphic card that has DP, but no 2.0 HDMI would be with this adapter. Which is why the OP and other people in the thread were looking for it. Now it appears it's actually here, even if we have no more info to go on at the time (or I haven't found it yet).

Edit:
For those more technical than me it's actually a 4:2:0 chroma subsampling what you need for 4k@60 on 1.4 HDMI
