Also, just found a tweet of Dutch company called Club 3D saying that they are releasing DP to HDMI 2.0 adapter soon with an image of actual package:

Just spotted a USB-C to HDMI 2.0 cable from accell.
accellcables.com/collections/adapters/products/usb-c-to-hdmi-2-0-adapter

This must be using a chip to convert DP to HDMI 2.0 because it's saying:
Quote:
The USB-C to HDMI 2.0 Adapter supports all USB-C devices with DisplayPort ALT mode and operating systems, including Mac, Windows and Google. For this HDMI video adapter to work from a USB-C port, the USB-C port must support DisplayPort Alternate (ALT) mode.
unless it requires alt mode of DP 1.3 which is HDMI 2.0 compatible naively.

I also saw the USB-C to HDMI 2.0 cable today (out of stock mind you). Having a X79 mobo i don't have USB3.1 but i found the ASRock USB3.1/A+C PCIe expansion card. I haven't seen any where that says it either supports or doesn't support DisplayPort Alternate mode, I've sent ASRock an email to ask but if i can find a USB-C to HDMI 2.0 adapter in stock i might take the leap and just return them if they don't work.

I'm a bit of a newbie to 4k displays (just got mine a month ago), but I believe the output color depth should be 12bcc instead of 8, but there is no option to up it to 12bcc at 3840x2160 (though I can use the 12bcc at 1080p - makes sense). I left a comment on the review that claims the adapter outputs HDMI 2.0 at Amazon (here: amazon.com/review/R1HNE3EKMBW0HX/ref=cm_cr_dp_cmt?ie=UTF8&ASIN=B00ZA067MA&channel=d etail-glance&nodeID=172282&store=electronics#wasThisHelp ful), but it's largely invisible since it hasn't been upvoted.

Given the $11 price tag and no claims on the product to actually convert to HDMI 2.0, I probably should have expected this. Worth a shot though.
have you tried a program like Custom Resolution Utility (CRU). for instance, my vizio P652 can accept 1080p 120hz, but by default my computer / AMD does not see that and will not allow me to select that refresh rate.

i used CRU to manually create a 1080p 120hz option in my display properties. now that it shows up i can select it, and my tv accepts/displays it. maybe you need to create a custom 4k 60hz setting?

OS X 10 now supports Single Link DP 1.2 (via Thunderbolt) at UHD 60Hz. May only be 4:2:0 but for watching video that should be fine.

I have to wonder if there is a legal need to include HDCP 2.2. Otherwise why has no company actually delivered one?

Hi guys,

I found a mini DP 1.2 to HDMI 2.0 adapter on the Raidsonic german website, it's called the IB-AC506

They say: "The IB-AC506 converts Mini DisplayPort in a true HDMI 2.0 4K signal"

I'm going to buy it and test it, and give you guys a feedback wether it works or not.

I'll test it on a R9 295X2.

Club3D DP 1.2 to HDMI 2.0 adapters should show up this month (a bird told me)
FYI: get a DP adapter, USB-C is still new and have at least 4-5 years to be useful, DP 1.2 has been out since 2009 and is still relevant to this day, most of the graphics cards on the market since the Radeon HD 7970 series has it (might work with 5870, but needs to be confirmed)

DP1.2 to HDMI 2.0 adapter

Thanks for this thread you guys.
I've searched everywhere looking for a DP1.2 to HDMI 2.0 adapter. I was baffled at why I couldn't find anything.
After reading this thread from start to finish, I was really hoping to find a link to an adapter by the end... but I guess I'll be waiting with you guys.

it works, it just doesn't say guaranteed on the box!

Okay...Okay...

Spent hours researching and found this thread.

Let me get this right and hope that this is the dream adapter I need.

I have a 27" 5k Retina iMac.

I want to run it to a 55" Samsung 4k UHD television via HDMI.

In the past, with this kind of connection, the Samsung would only support 30Hz.

The cable is getting positive reviews on Amazon. That's a plus.

Will this cable allow me to output from my Mac to Samsung TV at 60hz?

Yes, I've ordered the DP version: Amazon[dot]com/dp/B00ZA067MA
However, I don't have high expectations and will just use it until something official comes along.

The only way to know for sure is to try, but what we do know is right now is for only $11 it's the best option we have until the coming official DP1.2 to HDMI 2.0 adapters hit the market.
Also, your Samsung TV must have a HDMI 2.0 (probably does being 4K) to ever run 60Hz.

I've ordered both the mDP and DP versions of that adapter and can't get either to give me 60Hz on my Samsung 4K UHD JU6700.

I'm using the DP one with an Asus Chromebox which, honestly, I'm not sure supports 60Hz anyway (I can get 30Hz just fine).

I tried the mDP one with an early 2015 Macbook Pro 13" Retina and haven't had any luck there either. For some reason it thinks the TV is a 121" 8k display!? It turns out that the display driver is limited to a 165 pixel clock by default and I had to run a patch to fix that, which helped the mac detect the TV but still didn't get me to 60Hz.

I'm really hoping the Club3d adapters make an appearance soon...

Red face Found One?

Okay, I found one for sale.
One guy over at Toms claims it works and that he was able to run 3 50" TV's @ 4k at UHD 4096x2160 at 60Hz using 2x GTX980ti

The site claims 4k at 3840x2160@60Hz. This could be legit.

I don't have enough posts to post a link, so this is the best I can do:

www[.]uptab[.]com/displayport-to-hdmi-4kat60hz-adapter-cable-gold-plated.html

maybe a mod can fix my link.

That looks just like the aLLreLi on Amazon, just more expensive... The Parade chip in the pic is the same older version. I wonder if they silently upgraded them to the new chip and I just happened to get one from an older batch?

That's a good question. Yes, the photo's look identical to the amazon one that's interesting. They do list it as a "New" product and advertise it as a Display Port to HDMI 2.0 product, so there is that difference.
Basically, they are either the first to market that I can find or slightly untruthful.

And then the question is will it do the 4:4:4 colorspace? Been using an EVGA 780Ti classified and can get 4K@60 but no 4:4:4. with HDMI. The 780Ti has display port which will give me 4K@60 4:4:4 but we know how rare finding a display with display port is....Panasonic model, and some of the Korean monitors support DP. So would be great to get an adapter that does supports 4K@60 4:4:4.

I tried the amazon adapter and it does NOT work for 4K @ 60hz.

AMD R9 295x2
Samsung 55JS7000

Fails to do anything other than 4K @ 30hz.

thanks for the heads up on the amazon adapter.

uptab.com was selling a 4k 60hz adapter for $50. i am also part of a toms hardware thread on this. a guy said the uptab cable was the same as the amazon. he also said he contacted allreli (amazon cable company) and they confirmed the cables they sell now from the same listing no longer do 4k 60hz. around the same time uptab went out of stock of their marketed 4k 60hz cable. i think uptab was just drop shipping the amazon cable and making an extra $30 bucks on it.

i commented on accells facebook page, they responded that if all goes well they are on track for releasing their version by end of December. i also wrote an email to club-3d.com i think this last monday . they have not gotten back. they use to have a pic of the cable on their main page with a coming soon banner, but that pic was replaced by some dumb usb type c cables.

i just contacted cable matters, hopefully they will get back soon.

belkin chat doesnt know anything, so i tweeted them right now as well.

i'm going crazy here. Thinking of getting the 60' 4k Vizio 120Hz TV. Only problem is I have a GTX 780 ti with DP 1.2

If I do get this TV, i'll have to run it @1080p 120Hz native for movies and gaming until they release the adapter. Really frustrating being a slave to a simple cable.

Curious gentlemen, do you have a ballpark figure as to what these cables/adapters will go for?

1) you would still be able to play/get 4k 30hz for now with the tv. (which is how i have been playing gta 5 and far cry 4, i like it more then 1080p at 120hz)

2) you wont be getting above 4k 30hz/fps with many games and that card anyways, (besides minecraft).

3) no one knows, since we dont work for the companies. but it wouldn't be far fetched for the cable to be $20-$30 when first released (from major companies like belkin). but once its a common cable and Chinese companies jump on, it will be $10 (this is based off of current prices for regular mini dp to hdmi 1.4 adapters).

I'm well ware that my 780 ti is no match for 4K gaming, but since I plan using the display as a monitor as well I figure 60Hz is defiantly needed for daily use.

Thank you for keeping us updated on the potential availability of these cables.

you really dont need 60hz for regular monitor use, but i agree it would be nice. i use my PC with my vizio p652 at 4k 30hz and its been perfectly fine for web browsing/ word processing / gaming / watching movies and TV shows, etc. though i too want 4k 60hz for gaming (and maybe for some go pro editing).



cable matters got back to me.

Hi Carlos,

Thanks for the reply.

Currently, we are in the process of engineering an adapter that will do 4k @ 60hz but we don't have one yet available. The chipset to support this is just now becoming available so it will be a little while until it actually makes it in the hands of the cable and adapter manufacturers like ourselves. I don't have a timeline yet to provide but can say it is definitely months away.

Thanks,

Sean
