Unfortunately this cable CANNOT support a 4K 120Hz RGB 12-bit signal. This is an extreme use case, but I bought this "certified" cable believing that this could work. I've since replaced it with another cable that actually works.

The product is not as described or defective. Website says these should be marked as HDMI 2.1 certified. They were simply in clear plastic bags and the cables have no marking on them indicating they are high speed. I have been A/B'ing with another cable and these cables are dropping audio and video once or twice every 20 to 30 mins. I have asked for a return.

FAKE CABLE! item is NOT an 8k hdmi 2.1 cable. Purchased for the ps5, waited over a week for delivery and it would not work with my new 120hz TV. Tried it with my 144hz monitor and after checking display settings this cable isn't capable of 120hz in any resolution. You'd think the cable itself would have some sort of markings but Primecables just slaps a sticker on the bag to justify the price increase and sell fake 2.1 cables.

Ce câble n’a pas amélioré la qualité de l’image du tout.Il est arrivé sans aucune impression dessus le fil lui même.Ca pourrait être un fil du dollar store.J’ai demandé pour faire un retour à primecables mais pas de nouvelles.Allors je crois bien que ce sera ma dernière commande.
