> It needs to support DP-Alt-Mode For future reference, a Thunderbolt 3 cable (which is USB-C connector) will work.

Also the most expensive option and limited in terms of maximum length.

  How are the Thunderbolt cables wired? Do they have more than the 10 USB3 wires or is it just a higher standard of cable? Isn't USB4 = the next Thunderbolt standard?

Not true! Active thunderbolt 3 cables often only support thunderbolt 3.

  Per the Thunderbolt FAQ [1] > What is Thunderbolt 3? > Computer ports with Thunderbolt 3 provide 40Gbps Thunderbolt – double the speed of the previous generation, USB 3.1 10Gbps, and DisplayPort 1.2. I'm curious: which active cable did you use that didn't support DP? [1] https://thunderbolttechnology.net/tech/faq https://thunderbolttechnology.net/tech/faq

Only the 1-meter active cable can.

      Well shit, I stand corrected. Thanks for the links!

    What you quote is not related at all to what Thunderbolt cables support beside Thunderbolt. It just states that you can use Thunderbolt to transmit DisplayPort signals. By that you're utilizing the Thunderbolt alternate mode to tunnel DisplayPort signals, instead of using the DisplayPort alternate mode [1]. Using Thunderbolt to transmit DisplayPort signals only works with devices which support Thunderbolt, not with screens supporting "just" DisplayPort. To make confusion even worse: All existing Thunderbolt controllers also support the DisplayPort alternate mode, so a lot of people who believe they're using Thunderbolt are probably just using the DisplayPort alternate mode instead. Afaik Thunderbolt cables usually support both, but I'm not sure if that's mandated somehow.

      Thanks for the clarification. What a clusterfuck of a standard.
