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

Is there a release date for this or any manufacturer who's making one of these?

I contacted Bizlink yesterday and they replied, saying the adapter "is expected to be released around April." Accel is their retail product division and you can by Accel products at Amazon, NewEgg, etc. - so I expect that once the adapter is released, it should be easy to get a hold of it.

I bought recently one 2MMDPHDMI (just google it and go to visionaudiovisual for the manufacturer's site as I can't post links) that clearly advertised HDMI 2.0 with active adapter. However with a 590 gtx and with a 7990 amd I am having no success at all. (well, with the nvidia I managed to force it to 60hz but the tv sees the input as 30hz as well).
Since it recently became available (middle feburary) and it specified HDMI 2 I had high hopes.

Anyone else knows something about what I could try to make it work?

both those cards are a bit older. what version DP do they have? are you certain they are 1.2? also, the only page that comes up that is even similar is audiovisualsupport which does NOT say anything about HDMI 2.0 , can you provide a link to the product.

looks promising. i found some specs online the 590 only has DP 1.1a, so that might not be the best card to test with. the 7990 has 1.2. i would use that card to test, just make sure it has the latest firmware/drivers installed.

Oops, yes, the 590 only has 1.1. I was not giving up on it because it allowed me to try different timings on the output and I got it to see the "display" as 60hz (though it's probably the active part of the cable). The tv however continued to report it as 30hz.
With amd I can't seem to find any "advanced" settings. In CCC in desktop properties I have 2 categories Basic with all the resolutions but limited to 30hz and HDTV limited to 1080 60hz. (anything over 30hz is in italics and automatically pushes it to HDTV).

I had the omega drivers and I can't find any newer beta drivers. As for the firmware, I'm upgrading it soon but I don't think it will change much. the newest I could find was 015.032.000.004.002985.

According to the posted reviews, it will drive a 4K monitor. I'll let you know if it works.

Have you heard anything else, Xevious? Should be any day now for these Adapters

Just plugged it in...and it works! Two 4k monitors driven by a nvidea gtx 980. Awesome! It might be able to drive four 4K's?

According to one of the reviews it can do DP 1.2 to HDMI 2.0 @ 4k/60Hz. Could you test this out?

Nope! The NVCP only allows 30 Hz max, at 3840 x 2160. The best I can do at 60 Hz is 1080 P, 1920 x 1080.

Oh well, we will have to wait for DisplayPort 1.2 to HDMI 2.0 Adapter. Paradetech.com said they will have one Q2’15. Hopefully more manufacturers are working on these and will have one sooner.

I'm running two Seiki 39" displays. I believe the 30 hz limitation is from the TV? But at only $ 339 each.....

Yes, the Seiki uses HDMI 1.4 which limits 4k to 30hz
