Hello!

I'm interested in latitude 5400 laptop, but I'm confused with Thunderbolt 3 support.

From specs on product page:

Ports & Slots:

USB Type C 3.1 Gen 2 with Power Delivery & DisplayPort (Optional Thunderbolt 3)

I'm confused with "optional". What does it mean?

I've found Latitude 5400-5901 model In my local store. Does this model support Thunderbolt 3?

Than You in advance
