not seen any UK seller as of yet.
Zeskit is in discussions with Amazon UK as we speak. They are in the account verification phase but it is taking longer than expected due to CV-19. Hopefully they will be setup and ready to order/ship in the next couple of weeks.Also looking for this in the UK. Import fees on Amazon US are almost as much as the cable.
HDTVTest recommended according to this video.
Agreed. Belkin was pushing cables "certified for HDMI 2.1" months before the final ratification of the HDMI 2.1 option sets so their claims have always been suspect. That being said, if they are now offering Ultra High Speed HDMI cables with the QR label on the packaging then that would be fine. However, Belkin's reputation, at least for me, is about the same as Audioquest and Rocketfish, which is not very good. Zeskit or Ruipro (when released in January) are what I'd recommend. But, if they are truly certified......Unfortunately Belkin are another company who think that their Brand name allows them to gauge their (potential customers), no thanks.
The product description is pretty much boiler plate cable speak that hits all of the marketing points. However, they are marketing it as Ultra High Speed HDMI and do give the HDMI 2.1 options sets that has been tested, and passed for but the indicated that they haven't received their Certificate of Authenticity (QR label) so I'd wait until you can scan the code and verify the cable. It probably will be certified but there have been some counterfeit cables reported that looked and sounded just as good.
Do keep in mind that the passive UHS HDMI cables are not very flexible due to the wire gauge necessary to meet the HDMI 2.1 requirements, so give yourself some slack to connect your cables because you do not want any sharp or crimped bends which will affect the signal propagation and may put undue strain on the HDMI ports.
It could be any number of things. There were some issues with XSX and their HDMI chipsets reported so I'd try different settings (tv/XBox) and see if there is a setting combo that is problem-free. It might not be what you want but if it works ........
It's possible that you could have received a faulty cable but I would certainly check out how you have the cable installed. The biggest drawback of the UHS HDMI cables is that they have a thicker wire gauge due to the bandwidth requirements of HDMI 2.1 so any crimping of the cable or stress at the HDMI port can affect the signal. I had my cables coiled up a bit behind my setup, similar to yours, but had to lossen up the coiling a bit before my picture issues went away.
Do you use ARC/CEC by any chance?
Those are the same cables that I have, only mine came with the certified QR label of authenticity on the outside of the box. The cable box also has the name of Maya on it. Zeskit has been in negotiations with Amazon UK for quite some time now to carry their cables but whether those are the cables with the QR label or not is hard to tell. Amazon US did have the first set of cables without the labels because Zeskit hadn't received them in time to affix to the boxes so Amazon was randomly shipping the cables until their stock of unlabled cables was depleted. Zeskit assure me that the cables are exactly the same, but.....
'Does anyone know if the XSX cable is true HDMI 2.1?' - you can guarantee it is not as there is no certification for an HDMI '2.1' cable.
If it is a Certified UHS HDMI cable it ought to carry the QR code on the packaging - just as every other version of HDMI cables there will be a myriad of designs, thick, thin etc
The QR code is the only way to know you have a genuine certified UHS HDMI cable.

Nope. If it is a certified UHS HDMI cable it has to come with the QR label on the packaging or somewhere in the documentation AND the HDMI 2.1 option sets that it has been certified for must be listed according to the HDMI 2.1 marketing and product description requirements. The only way the cable can be tested, without the use of sophisticated testing equipment, is to run source material (if available) and see if you get the expected results. The cable may very well be capable of 40Gbps (maybe a bit higher) but that just means the cable is capable of transferring data at that bandwidth, which is totally dependent on the source HDMI chipsets.True but the xbox series x cable is just chucked in the box it doesn't come in separate packaging, I think Vincent confirmed it was a hdmi 2.1 ultra high speed cable, I'm guessing he tested it somehow. it might not carry the certification but its capable of the high speeds.
