Ensure That Your System is Equipped With a Thunderbolt 3 Controller
While many Dell systems are equipped with a USB Type-C port, many of these systems do not have the optional Thunderbolt 3 controller. These systems have the USB Type-C port which can be used with Thunderbolt 3 on systems that are so equipped, but USB Type-C is the default port (Without Thunderbolt) for several systems.
Types of USB Type-C ports:
- Power or Charge Battery
- Data use only (select systems only)
- Display Port over USB
- Thunderbolt 3 device support (Optional on many systems, Standard on select systems)
These systems have USB Type-C but DO NOT HAVE Thunderbolt 3 capability:
