Silkland DisplayPort 2.1 DP80 2 Meter Cable? Will this actually work?

Hey all,

With the release of the RTX 5090 around the corner, I've been trying to find DisplayPort 2.1 cables that will allow me to use my Samsung G9 57" to its full capability. With my current PC/monitor location, the cable that came with my G9 is just too short. I know that the DisplayPort 2.1b spec was just announced, but sadly those cables won't be available for purchase until this Spring, so I'm trying to find alternatives until then.

I was doing some research, and heard that DisplayPort 2.1 cables that are DP80 certified only exist in a length up to 1.3 meters. But when I looked at the list of DP80 certified cables on the DisplayPort website, I saw a 2 meter cable from Silkland on the list (Amazon). Is this something that would actually work to run my G9 at 7680x2160 @ 240Hz? I'm skeptical since everyone that's spoken on this topic has said these cables don't "exist" this long, and the whole reason the DP2.1b spec was released was to fix the issue of DP2.1 cables being so short.

Hopefully someone either has experience with this cable, or knowledge about if this cable is just too good to be true. Thank you :)
