You won’t find these symbols on most devices though (certainly not on any macbook as the picture suggests).

It gets even better, each function of the port also needs proper support from the cable. Often cables do not support the full spec of usb to cut costs.

While the symbols in the post are often put on computers, for usb cables this is seldom done (only a few brands do).

Source: had to find a cable that supports both DP and PD to connect a portable external monitor after I lost the original cable. (1/9 cables worked)

Can we stop naming things “super speed” they are going to get surpassed in a few years then we are stuck with super speed being the slow option.
