Club 3D CAC-1372 Ultra High Speed HDMI Cable 10K 120Hz Black

I was weary at first given earlier reviews, but I believe the manufacturer, despite producing the cables to HDMI2.1 specification, started selling them before the certification was officially granted and were able to print relevant 2.1 certified QR Codes on their packaging.These are indeed HDMI 2.1 certified cables and are correctly recognized to support VRR, 4K @120Hz on my CX OLED and HDMI 2.1 compatible GPU.Ive given these 4 stars overall, as I think these are very pricey for what they are. But then again these are pretty much the only genuine, certified cables you can buy in the UK. So hopefully with time the pricing should normalize.

Using their DP to HDMI adapter with this cable, I am finally able to get 120Hz 4k on our Samsung QN90A TV. Tried other cables and it wouldn't have it.

Well I can confirm it does have a qr code on the box which you can scan and it takes you to the Google play store to download an app which confirms I've got a certified cable. Great I thought, it should work with my hdmi 2.1 equipped lenovo legion 5 with rtx 3070 laptop and my b9 oled. Tried everything. Even tried other supposedly certified cables and no matter what I do I can't get 4k 120hz to work. The highest I can get is 1440p 120hz with hdr and gsync enabled. Yes I've got the latest drivers and firmware.

Contrary to other reviews, these cables are now shipping with the HDMI 2.1 scannable holographic to verify that it meets the standards of Ultra High Speed HDMI.

Tempted to go down to 2meters as at 3meters RTX3090 to LG C9 oled running engineer firmware 5.10.02 gets the odd dropout like once per hour for a second. Only buy the length you need. DO NOT ORDER MORE LENGTH THAN YOU NEED - even these high spec cables have not been certified yet. If Club3d think I'm incorrect please reach out to me as I'd be happy to swap out for a shorter cable without requiring a partial refund.EDIT: Figured it out - the cable I got only has High Speed Club 3d on it so it's not the same as the others on these reviews so I will take it up with Amazon.

No HDMI QR code on the box as stated on the advert to prove the cable is certified as ultra high speed by HDMI. Only paid over the odds for this privilege otherwise I would have gone with the many other claimed ultra high speed HDMI 2.1 cables on Amazon.

Very disappointed. As the item, as pictured, doesn't have the certified QR code. I didnt even take it out of the sealed bag inside the box to test, and I sent it back. I also checked the HDMI.ORG certified adopters and Club 3D are not listed (unless they come under another company name). Amazon have falsely advertised this product via the pictures, albeit the last picture as its the same packaging that I received. YOU HAVE BEEN WARNED, IF YOU WANT A CERTIFIED 2.1 HDMI CABLE WITH SCANABLE QR CERTIFIED CODE THEN LOOK ELSE WHERE, I am still looking. I Did find Zeskit but not available in the UK....Hope this helps and GOOD LUCK
