Our community has rated this post as helpful. If you agree, why not thank KO3bIPb

If anyone cares, this cable really was USB-IF certified on 02/17/2026 FWIW

The price, though, is far from being a hot deal.

Price is about fair.

Realize this is USB4 certified, not just a generic 240W USB-C cable, which usually meet the 240W spec for charging but have low data rate. The use case for this would be going to a USB-C dock with multiple monitors out.

I realize it's Cable Matters product, but is it that much better than a $5 80Gbps/240W cable off Ali? Granted I don't have an E-Marker reader, but so far those Chinese cables have been powering 4K monitors without any issues. Genuinely curious about the difference of any.

Yes absolutely, especially at 5ft length. Signal loss and distortion is significant. So significant that it took years for cable manufacturers to be able to build a cable that passed specification criteria. That $5 cable may or may not actually work at 80Gbps, and even if it does with one device it may not with the next.

Note that if in your example you're driving a 4k60Hz display it's only consuming about 12-13Gbps of bandwidth, so there's tons of overhead and the link may only be 20Gbps if using USB4/Thunderbolt or 4x HBR2 5.4Gbps if using DisplayPort alt mode.
