4k displayport 1.2 to 4k HDMI 2.0 tv

[Inky_Enston]

If the issue is only with bandwidth, namely 8gbit for HDMI 1.4, then wouldn't a 4k signal from displayport 1.2 to a 4k tv equipped with HDMI 2.0 be ok with a standard adapter, since cables have no limitations, apparently? Has anyone tried this with a 4k HDMI 2.0 TV and achieved 60hz?

 

[carlosriosness]

just in case you guys are wondering the clubed cac-1170 mini dp to hdmi 2.0 cable is out. i pre ordered on amazon US, and i now have it in hand. i will test tonight.

note: my vizio p652 does not do 4k 60hz 4:4:4 anyways. but i will let you guys know what happens.

 

[Dwayne_8]

What i've read about 4K@60hz and 4:4:4 is it needs 18Gbps bandwith and what club-3d and accell says they support 18Gbps but they support 4K@60hz only on 4:2:0 which 8Gbps is enough. So if you use a driver that can show 4K@60hz 4:2:0 you can use a HDMI Cable and use the HDMI 1.4 port which is available almost all graphics cards. So accell and club-3d are lying or there's something that i don't know.

I got the Club3D one today it does work @ 60hz Hdmi 1.4 Can't push 60Hz for 4k there is not enough bandwidth your talking out ur ass. I can't get 10 BPP in 4k yet and my tv can do it.

 

[carlosriosness]

i also read you need 18Gb to push 4k 60hz 4:4:4

either way, i got the CAC-1170 to work on my vizio

my hardware:
1) cac-1170
1) monster platinum black hdmi cable (27GB rated)
1) vizio p652ui-b2
1) 295x2 - using mini dp port closest to dvi port

steps:
plugged in cable
opened device manager
scan for new hardware
went to resolution settings (already on 3840 x 2160)
clicked advanced
changed refresh from 30-60
apply and it works

i can tell right away that the scrolling looks much smoother.

I'm not aware of many TVs that can support 10bpc (bpp = bpc). Do you own the lg oled 4k, I know that one can? Here's the issue though. Hdmi 2.0 18gbps bandwidth is trash, it's a trash standard. All these settings are a limitation of the HDMI 2.0 bandwidth, as color profile gets worse, you can increase bpc, I'll expand on this more.

Max pbc per color format (HDMI 2.0 based on bandwidth):
(4k@60hz for all)

YCbCr 420
8 or 12 bpc

YCbCr 422
8 or 10 or 12 bpc

YCbCr 444
8 bpc

RGB
8 bpc

Even though you can increase bpc using a lesser color format, you don't want to do this. The bpc for YCbCr is meaningless, because to quote Wikipedia

Y′CbCr is not an absolute color space; rather, it is a way of encoding RGB information.

Y′CbCr was never intended to be output from modern PCs, it was for CRT displays. It's a substandard color format. It has it's purposes, but not in this realm.
Although, because PC graphics cards can output this color format, there's been confusion.
Coincidentally the color difference between 8 / 10 pbc is unnoticeable to the human eye regardless of the above information.

As a personal owner of an lg oled 4k, the below settings look better than any Y′CbCr iteration.

Color Format: RGB
Color Depth: 8 bpc
Dynamic Range: Full

Is there any displayport to HDMI solution that can actually achieve a 4096p@60hz signal?

From what I can read the CAC-1070/CAC-1170 can handle max. 3840p correct?

i will have to confirm when i get home, but i think the cac-1170 does. i did notice my vizio p652 has both 4096 and 3840 resolution options. i am pretty sure when playing with the settings after getting the adapter that 4096 also worked at 60hz.

You were right!

I just checked again their website and it says

Maximum resolution:

4K UHD 4096x2160p @60Hz

Did any of you who got the cac-1070 to work do anything special? Just got mine yesterday with a monster platinum hdmi cable and i keep getting "resolution not supported/no signal" all the time. I have a 4k samsung tv and r9 290x in crossfire...

i have the 1170, but , my steps:

1) start with tv and computer off
2) connected adapter and hdmi cable in place
3) turn on computer and tv
4) before changing from 30 to 60hz i opened device manager, right click computer name and click scan for new hardware
5) then went to display properties, resolution, advanced, monitor then changed from 30 to 60hz.


are you using windows to change resolution? are you using customer resolution utility to create the resolution?

my computer recognized 60hz, but to get 120hz 1080p i had to create the resolution with CRU.

@ninjawithagun Cables are the same. Apparently, aside from quality, all HDMI cables carry both version's of the signal, accept HDMI cables that upscale for the few 4k TV's that don't upscale (folk claiming they sell HDMI 2.0 cables are con merchant's). There is also no such thing as a displayport to HDMI 2.0 adapter, which is why I was asking, has anybody tried Displayport 1.2 4k to HDMI 2.0 4k tv

You are correct. Currently, the DisplayPort-to-HDMI adapters only support up to 4K @ 30Hz. What graphics card do you have? If you have one of the latest Nvidia cards, they come with an HDMI 2.0 port that fully supports 4K @ 60Hz. I know the GTX970 and GTX980 both support it. That means no converter cables would be required.

Hi sorry bit confused by that are you saying that the hdmi 2.0 are converter cables and that the 980 can use a standard hdmi cable and get 4k 60hz?

Has anyone had a chance to test an AMD card with the DP -> HDMI adapter from uptab.com yet (http://www.uptab.com/displayport-to-hdmi-4kat60hz-adapter-cable-gold-plated.html)?

If it can really port 4K @ 60Hz, from DisplayPort to HDMI 2.0, this would be a huge deal for anyone with a high-end Radeon, as I'm sure I'm not the only one interested in getting the most out of their UHDTV! I'd expect a lot more feedback from the community if this was for real, so if anyone has any first-hand experience with this $50 adapter, please let us know if it's the real deal?! =)

I bought the adapter and it does support 4k @60hz but only at 4:2:0 not the full 4:4:4 chroma subsampling.

Cool, okay - thanks for the update! I'm sorry to hear it's only 4:2:0 and not 4:4:4, but at least it actually does put out 60Hz.

They just released new adapter with latest Parade chip PS176 which supports HDMI 2.0a with full chroma 4:4:4 They have Mini Display Port and DisplayPort with HDMI 2.0a

i wish people would stop linking uptab. the site just seems shady. all they do is relist the same products found on amazon but at nearly double the price. save your money, dont give it to crooks.

But even on its website, the brand sold on Amazon--Micro SATA Cables--doesn't offer a 60Hz adapter for DisplayPort; only for Mini DisplayPort.

you got me there. if i absoultely needed a dp to hdmi 2.0 today. i guess uptab is the only option. but i would prefer to wait for the club3d to restock if i could.

i did order the micro sata mini dp version from amazon and should get it friday. i will try to test it sometime early next week (if not friday), and give an update on if it works the same as the club3d cable did for me.

Yes you are correct it can do RGB 420/422 10 bits will probably come when AMD enables HDR support.

Guys,
I earlier requested tips on how to make this work and I've been unsuccessful with every solution. This was until i red that there was a firmware update for the dp adapter. AND THE FIRMWARE ACTUALLY WORKED!!
Club3d havent uploaded it for everyone and one is supposed to send a mail to their support asking them to send it to you. For me it took 2 days to recieve it from the day i sent an inqury. If you dont want to wait the link is here: https://www.dropbox.com/sh/eh6zk0j33lv4nvj/AADOTAKJnBzOKJHN5P1kmJeWa?dl=0

Please check:

* Color Depth (often default set to 16 bits or even 32 bits) need to be set to 8 bits.
* Make sure the HDMI port your using on the TV is HDMI 2.0 capable or 3840x2160p 60HZ capable.

Often TV's have like 4 HDMI ports, but only 1 is suited for "2.0" standard.

* On many TV’s you need to turn on "UHD Color" manually in the settings of your TV for the HDMI port to which your pc is connected.

* Also it could help when connecting 2 screens, to set the screen connected thru the Adapter as second/secondary screen.


When installing the firmware first launch the .exe file. Choose "Get firware info" Make sure it says "Firmware version num: "0x07 0x0e"
If it does click "download firmware". After it is completed reboot machine. Run program again and hit "get firmware info". It should now be some other numbers and if it is you have updated the fw successfully.

Here is the link to the Parade PS176 chipset that I believe is used in the
Accell and Club3D 4k displayport 1.2 to 4k HDMI 2.0 adapters:

So most of you say it's working with DP to HDMI 2.0 adapter. I live in Europe. Will you please tell where and which one i can buy? I checked amazon and club 3d items are out of stock. Do you think cheaper oem/no brand products will be available soon?
Thank you

 

[okiejay1]

The Club3D Displayport 1.2 to HDMI 2.0 UHD (CAC-1070) Active adapter is supposed to be back in stock at Amazon.com on 3-24-16 .

You can order it now, and be first in line to get it shipped out when it arrives at Amazon.

Both the Club3D Displayport 1.2 to HDMI 2.0 UHD (CAC-1070) Active adapter and the Accell (B086B-011B) DisplayPort 1.2 to HDMI 2.0 Active adapter are based on Parade Technology's PS-176 chipset.

I found the Club3D CAC-1070 in stock at MacMall:

One thing that may not have been mentioned about Displayport to HDMI adapters is that I have noted that some older video cards with Displayport outputs will do 4K using an adapter even though the card is not rated to do 4K. However, the 4K does not work through the card's HDMI or DVI (with passive DVI to HDMI dongle) outputs. Specially, this works on a HD5770 and a FirePro V5800 Whereas most newer cards work in 4K directly using their HDMI output, although many lower end cards will only do 30Hz refresh at 4K. One noted exception is the Quadro K420 which will do 4K and 60Hz with a DVI to HDMI cord or passive dongle.

Not to restart, but this is only recent thread I can find on the subject. I have the uptab displayport to hdmi 2.0 adapter. My card is an r9 390 nitro and my TV is a Sony xbr55x810c. It does all the resolutions though in 1920 x 1080 @ 120hz I get some white lines randomly appearing all over the screen. I like how the 120 hz displays short of that. It does it thru all do. I use Radeon setting to custom set base resolution. So I guess I'm asking how to get rid of the lines if possible. Thanks
