USB 3.2 is not Thunderbolt. USB 3.2 achieves 20Gbit/s with signalling that is entirely incompatible with Thunderbolt signalling. It is completely possible to have a 20Gbit/s USB 3.2 port that has no Thunderbolt capabilities.

The first USB standard to incorporate Thunderbolt functionality is USB 4.

i stand corrected. it is indeed usb4.

the point i made is just as true though, as the announcement that thunderbolt switched to the usb-c form-factor is 6yrs old now. (and was even linked to from someone else in this thread!)

the downvotes just show once again how hilariously dumb the average hn-reader is.

It doesn't matter whether the point you were trying to make is true or not, because Thunderbolt is irrelevant to the problem that was described. DP Alt mode is not the same thing as encapsulating a DisplayPort stream in Thunderbolt signalling, so knowing which of your laptop's Type-C ports is Thunderbolt-capable does not tell you anything about which of the ports is capable of DP Alt mode.

Stop calling people dumb until you can make a comment that is at least somewhat correct and on-topic.
