This is my only qualm with all the different standards. I just want some way, any way at all, to tell whether stuff works the way it's supposed to. Either label the cords and outlets (via printed acronyms, or color-coding, or cryptic symbols, I don't care), or provide the information software-side. I can't believe Microsoft and Apple haven't built this into their operating systems. Sometimes it's near-impossible to figure out what Bluetooth standard I'm using, or HDMI, or USB, and I feel like it wouldn't be a monstrously hard problem to solve, as long as the devices are already successfully talking to each other.
