So we dont need to wait for HDMI 2.1 videocards anymore? Interesting. Its just a year late or so.

I wonder if this Club3D product be actually purchaseable, or just another announced product that we will never see.

I don't see any mention of VRR being supported?
Since the LG OLED's have that feature, it would be nice to know whether it works through this.

Am I the only one noticing the very conspicuous absence of "HDMI 2.1" in this? Is it not compliant? Is it a hacked-together solution that is just compliant enough to work, but not enough to use the branding? This feels a bit disconcerting ...

I tweeted to club3d to ask them if this adapter supports variable refresh rate and I will report back as soon as they answer. Hopefully they will, I only have a Twitter account because I signed up for giveaway a few years ago and have only used it twice for support reasons like this, so hopefully they don't think it's a bot or something.

"ith its DP1.4 DSC video compression technology, this adapter is able to convert DP1.4 video signals to HDMI 2.1..."

The actual text of the press release specifies "HDMI 2.1", did you just look at the graphics or are you specifically looking for the visual logo of HDMI?

I did read, I just didn't read that far down :P Tbh, I was expecting everything below the fold to be yet another me-too overly braggy listing of bog-standard features, and I certainly wasn't expecting a core feature like that to be hidden that far down in the text. Still, very weird to not use HDMI 2.1 and instead use some weird non-standard "HDMI 4k120Hz HDR" branding in the pictures.

So in theory a GTX980 with display port could use this adapter on a 4K 120Hz display?

With new video cards set to launch in September I find my interest in this exact device has come and gone. I wish they were around a year ago when I was stuck with HDMI 2.0b but I'm already prepped to move to new gpu and sold my 2080ti already to get the maximum back before the price drops.

If you're not planning to upgrade I guess this could be nice only problem is the need for 4k/120 also comes with the demands of 4k/120 and nothing not even my 2080ti could come close to fulfilling that need.

Not only 4k120, but you can't even do full 4:4:4 chroma 10bit 4k60 with HDMI 2.0b. Also input lag is lower at the same framerate 4k120 vs 4k60.

I have their DP 1.4 cables. What a dream they are to work with, and I can't recommend them enough. This is not something I need, but if I did, I wouldn't even think twice, personally. Its nice when a company gives a sh!t about the products they put out.

VRR (G-Sync/FreeSync) is part of the HDMI 2.1 specification! If a certain device does not support VRR it is not HDMI 2.1 compliant. This is why Club 3D removed HDMI 2.1 from the spec sheet on their web site and are only specifying it as a Displayport 1.4 to HDMI 4K 120Hz

Because it doesn't lock users into a fixed cable length or other built-in limitations? Leaving the adapter as standalone as possible is great for flexibility.

Of course it is. Asking users to potentially buy two cables and an adapter is silly. Expecting users wanting to connect a HDMI device to have or buy a HDMI cable is reasonable. Besides, you will be buying this specifically if you have a DP output and want HDMI - so it having a DP plug is a natural fit. It is a unidirectional adapter after all, meant to convert your DP output (both signalling and physical interface) to HDMI. To do so necessitates a DP plug. Sure, you could argue that necessitates an adapter for mDP, but mDP has been dead for years. Also, DP cables are more expensive than HDMI cables (despite being royalty free; that's economies of scale for you), so only needing to buy the cheaper cable is good. If you're insinuating it should plug directly in, that would be concerning as it would put a lot of stress on the port, potentially breaking it. It is neither over nor under-engineered, it does precisely what it is supposed to do in a simple and functional way, while allowing for the near maximum of user freedom (for which the choice of HDMI cable is obviously the most important part).

You are assuming that the user will have a TV sitting 5 metres away from his graphics card, and that user won't use his GC's HDMI port.
Fixed cable length on the DP side is OK, while on the HDMI side the user is supposed to select whatever he chooses or likes.

WTH? Just have it both ends male and use it as a cable at least 2 metres in length.
It will be easier for the user.

This is for niche - someone who needs Eyefinity triple displays, for instance, and his GC's 3 DP and only 1 HDMI port is not OK.

What? I am the one here advocating that the user can choose their own cable length! How am I assuming anything at all? It could be 0.5m or 10m - it would still work, just get a suitable HDMI cable! You are the one making assumptions about people's use cases here, not me.
ARFand that user won't use his GC's HDMI port.
... who would buy this if their GPU already had a HDMI 2.1 port? The whole point of this is adding 2.1 support to GPUs that lack it.
ARFFixed cable length on the DP side is OK, while on the HDMI side the user is supposed to select whatever he chooses or likes.
Exactly! The DP cable is only there to relieve the port, so it doesn't need any length, and the user then gets to choose how long a HDMI cable they want/need - or even use one they already own, saving some money.
ARFWTH? Just have it both ends male and use it as a cable at least 2 metres in length.
It will be easier for the user.
So you want to force users with this hooked up to a TV to deal with storing a bunch of thick excess cabling in their TV stand or HiFi rack? Brilliant, real user friendly. And how about anyone needing a longer cable? They would need to find a HDMI 2.1 extension rather than just a cable. How easy and cheap is that, compared to just buying a long but otherwise normal cable? Obviously both more difficult and expensive.

No. See above. That is not the main use case for this.

How'd I miss this?

I have one of these on order. They are hard as hell to find right now. Mine is shipping from Amazon Poland... which is kind of amazing as that's literally the only one on earth I could find as of 4 days ago. It should be here Friday.

I will post a review when I get it, with my B9 OLED. And I'm using a 3 meter club3d HDMI 2.1 cable, for reference. That's already arrived.
gdallskI don't see any mention of VRR being supported?
It's not officially. That will be part of my review, to see if I can make it work (It's also not officially supported on my b9 OLED TV, but works fine with CRU).

I've actually been on a club3d wait list to get this thing and tracking it's development for months, it is certainly HDMI 2.1. I can even tell you the realtek converter chip they use if you want.
orionbgVRR (G-Sync/FreeSync) is part of the HDMI 2.1 specification!
It's an optional component, not a mandatory part.
resadentI'm afraid not. See this: insights.club-3d.com/thread/hdmi-2-1-to-displayport-1-4/ at the bottom of the page.
There are actually mixed signs it might be working, just janky as all get out. I'm going to investigate it well, you can be sure.
orionbgThis is why Club 3D removed HDMI 2.1 from the spec sheet on their web site and are only specifying it as a Displayport 1.4 to HDMI 4K 120Hz
It might have more to do with the fact they literally do not have a HDMI license or pay an adopter fee, at all. ;)

Not that it really matters. There literally isn't a cert process for hdmi 2.1 parts yet, only TVs/input sinks, so they couldn't get it if they wanted it.

Long story short, I have it, but am holding off on a review until Club3D has a chance to fix some bugs.

Out of the box it really doesn't work well with Radeon GPUs, at least. Not sure if it's a brand issue or if LG just falsely advertised my TV as HDMI 2.1 compatible, or the part doesn't work. So many things to diagnose.

I'd like to hear more context on this when you have a chance. The specific equipment you used namely the GPU, TV / monitor, the length and type and/or brand of cable(s) for connecting GPU and display

I too have an RX 5700 XT (going by your listed system specs) and would very likely purchase this adapter to go with a new TV purchase like LG's 48" CX OLED which can do 4K 120HZ. As everything being advertised in good faith, on paper that setup should perform just as expected. I noticed they had a mentioning of specific length and type of cable, so it seems important to make sure you are not using a standard HDMI 2.0 (2.0b) cable which wouldn't have the bandwidth required. Makes total sense to me of course. Also it seems many TV's are finicky with needing a specific "mode" enabled to ensure some or all of their inputs are able to accept the full bandwidth they are advertised at. Just some two cents stuff there, but I know it's basic stuff that most all ready know.
