alt Hacker NewsSome things don't work unless you use the right kind of USB-C cable.
EG your GPU and monitor both have a USB-C port. Plug them together with the right USB cable and you'll get images displayed. Plug them together with the wrong USB cable and you won't.
USB 3 didn't have this issue - every cable worked with every port.
That is not backward compatible problem. If a cable that does 100w charging when using pd2.0, but only 60w when using with pd3.1 device, then i would agree with you.
