Yeah, I don’t know how anyone can say this is not a problem. I’m sure there’s some deep technical reason why each cable does or doesn’t work, but as a user I have no idea why it’s the case or how I can figure out which cable will work where.
I thought I was being smart ordering some decent Anker cables until I found out when trying to connect a display that they apparently they only support charging? And maybe USB 2.0 transfer speeds?
So I went back looking to try and figure out what I needed instead. Depending on what the various devices involved support, I needed some variation of a thunderbolt cable (2, 3, or 4?) or a USB 3.1 Gen 1 Type C or a USB 3.1 Gen 2 Type C. But then I’m supposed to know something about thunderbolt versus DP alt mode versus god knows what else none of which is clearly labeled or explained anywhere on the devices I’m trying to connect.
But then there’s this handy table from Adafruit that says maybe not? https://learn.adafruit.com/assets/85323 https://learn.adafruit.com/assets/85323 — apparently only Thunderbolt supports video, or DisplayPort? And USB-C “full featured” cables are only for higher speed charging, not displays?

Anyway, turns out a USB 3.1 Gen 2 Type C cable worked for this specific display. Why? No idea. Will it work elsewhere? No idea.
I’ve been in the industry professionally for about 25 years now and I have no idea what cable I need to purchase and have no idea how to tell before I purchase whether it will work for a specific use case. I have no idea what non-technical people are expected to do with this besides try every cable they own and pray.
- shiroiuma 3y agoI have a Thunderbolt docking station for my laptop. There's no confusion about the cable, because the cable is permanently attached to the docking station. I just plug it into the laptop in the correct port (designated by the Thunderbolt logo). Are other docking stations not like this?
