was…  now that big navi will get released soon, we wont need the adapter anymore.

on 20-01-2020

I’m not quite ready to upgrade with two 1080 TI’s. But I might 😉

Club 3D better get it out if they want to sell the stuff

on 20-01-2020

I think in general its a mistake to announce a product if they wont release it soon after, it has been almost a year now and no more information has been given. Not a big deal as they are much bigger problems in life 🙂  but personally I lost interest in the adapter, and generally trust  AMD and nvidia more with releasing a product when they announce it.

on 20-01-2020

I think it’s wise to get native support

on 20-01-2020

the last 2 cables that i got from club 3d did not last a month.  ( hdmi 2.0 to dp 1.4 ) screen flashing black often etc… These kind of adapters are not stable.

on 20-01-2020

I may actually jump on board with good old AMD if they truly have a car that can beat the 2080ti

on 20-01-2020

the rx5950xt is rumored to be 30% faster than the 2080ti, for much cheaper.  But then the rtx 3080ti will be 50% faster than the 2080ti for a bit more expensive ( nvidia said that the 3080ti will be cheaper than the 2080ti at launch )  Honestly I ll just go for the first one to be released, as long as hdmi 2.1 is fully supported, and I can finally get my lg c9 at 4k 120hz, 10 bits 🙂

Hi,

Interesting info does anyone has a set date for HDMI2.1 to drop? 

as far as i know not even HDMI.org has set on the standard pf HDMI2.1 yet ?1

on 20-01-2020

BricoDepot1987,

Which HDMI cables did you have of club3d,if they failed within a month have you got replacements?

on 20-01-2020

we know for a fact that the Amd gpu inside de ps5 has hdmi 2.1 already .   Nvidia and amd also confirmed that their next gen gpu will be able to unlock 4k 120 fps full chroma on Lg C9 – C10 etc.   About the dates : everything will be out for this summer. The hdmi.org standard could just come after and is not important . In the past it was the same story with hdmi 2.0.

on 20-01-2020

as for the cables, i got 2x CAC 1080.  first one was working on and off, with black screen etc, then stopped working,  i bought a second one on amazon, and it was the same, I was runing a lg c9 4k 60hz 4.4.4 chroma  with a gtx1080ti. From what I understand, the voltage or something is not stable at this resolution and the cable damdages itself with time. ( and I am clearly not the only one that got the issue )

I did not try getting a free replacement as shipping where is live just takes too long.

Hi BricoDepot1987

Could you share your sources on the definitive inclusion of HDMI 2.1 on the AMD GPU and the PS5 i am not able to find that information. since i am a tech interested myself  i would love to read up on HDMI2.1 even I have been waiting on it for a while 🙂

on 20-01-2020

The information is given in a few CES interviews by youtubers etc. When asked about Lg cX capabilities, Nvidia representative states that today their graphics cards cant utilise full hdmi 2.1 capabilities, but that as soon as their next gpu is out, people will be able to use all of hdmi2.1 and also stated that lg c9 will be able to be ran at 4k 120hz 10bits at full chroma subsampling, with gsync etc.   As for Amd, it is known in the specs already that the Xbox series X and Ps5 have a custom Navi next gen gpu, that will enable 8k 60 hz gaming, as well as true 4k 120 hz through hdmi + Variable refresh rate etc .  ( we know that only hdmi 2.1 is capable of this )  Common sense then will tell you that if amd did include hdmi 2.1 on the ps5 and Xbox next gen Gpu, then they will also include it in the Rx5900xt series coming soon.

Lame

on 19-02-2020

Just forget about it 😀

on 19-02-2020

I guess development takes time.

Rumors have it somewhere Q2 of this year.

on 01-03-2020

I asked Club3d on Facebook, they said the end of March (This Month).

I hope it will get powered from the DP end, and not from the HDMI/USB. Or at least support all options.

I’m actually sitting on a prototype device with this function here to test, but its not Club3D’s. It’s powered from HDMI/USB wich makes it a bit awkward. It’s based on a Lontium Semiconductor chip. I expect others manufacturers will hit the marked in a few months too.

So far, it has some issues and it won’t connect to all DP sinks, but I expect those bugs to be resolved soon. Until then, I suggest to allow firmware upgrade from HDMI end, or even from DP end (a bit tricy but doable). The reason I want upgrades from DP end is that I’m working with video processing gear with DP sinks, where I have full control, and the devices attached are out of my control; The adapter will support the video processor, not the computer.

You have a prototype? How can I get in on that? Have you tested 4k 120 on c9?

on 29-02-2020

The prototype I have is a Rextron brand (no, not Extron) and is not yet available in the marked. I talked to Lontium and they expect chip availability in April, so I expect the marked to open up around that time.

on 07-03-2020

Hi,

Would this be HDMI2.1 to DP1.4 or HDMI2.0b to DP1.4?

on 08-03-2020

The Lontium chip early datasheet seems to suggest HDMI2.1 to DP1.4. I got an early sample wich may have limitations. Rextron claims its HDMI2.0 to DP1.2. I have not tested it beyond 4k60 4:4:4, as I don’t have any testgear for that atm. It could be the implementation (signal integrity) that limits the bandwidth, or it could be the early sample chip, or they havent tested beyond 600Mpps bandwidth. The HDMI2.1 part is less interesting to me right now.

Look what I found on the club3D website

https://club-3d.com/en/detail/2491/hdmit_to_displayportt_4k60hz_m-f_active_adapter/

on 07-03-2020

I see DP1.4 to HDMI 2.0b. Is that what you’re referring to?

Needs to be DP 1.4 to HDMI 2.1

on 07-03-2020

I asked OST if his version is the one you referring to. That would be interesting to know.

on 08-03-2020

Something funny with that URL, as when I first opened it, I (probably like net200777) got the DP->HDMI adapter up.. Working a bit more with the link I ended up with the CAC-1331, wich seems to be what we all look for. I wonder if its available.

“The Club 3D CAC-1331 is an HDMI™ to DisplayPort™ 1.2 Active Adapter which allows you to transmit a HDMI™ signal into a DisplayPort™signal. This product supports DP1.2 specification with resolution up to 4096 x [email protected] Besides, it is equipped with USB Type A port to supply power in case there isn’t enough power from HDMI™ source. This Adapter is Uni-Directional. “

on 08-03-2020

..but it bothers me that they didn’t power it from the DP end through a DP male cable tail on instead of that branching mess. A female DP plug can not utilize the power from DP, because the cable can not carry power, but a cable tail with DP male plug can utilize power from the sink’s DP port. The HDMI port is normally not dimensioned for this kind of power, so you end up with a cable mess.

The Club 3D CAC-1331 Adapter makes 4k / 60 Hz. We are all waiting for a solution with 4k / 120 Hz Support.

on 10-03-2020

You won’t get 4:4:4 at that rate. DSC most likely wont be that effective, so you need to wait for Displayport2.x to go there. Im pretty sure you dont have a sink that can handle that already 🙂
Bandwidth wise, you could get 4:2:0 at 120Hz over this adapter. Idk if the firmware will support it tho. I like to keep my pixels perfect tho. Color compression is “cheating”.

Any update to when this adapter will be released?

6 days ago

. To be honest , i simply think that both companies failed to produce a stable adapter. ( Realtek also never released it)

The current hdmi 2.0 to dp 1.2 is also very unstable and breaks after a few months of utilization ( if you use it fully at 4k 60 hz chroma 4.4.4 )
