Details of my Type-C of my laptop Latitude 7490
My laptop is a Latitude 7490.
I want to know the details of my Typce-C port. Is this thunderbolt 3/4? I need this information because I have 02 monitor. I want to extend these monitors with a docking station (Dell WD19TB Thunderbolt Docking Station with 180W AC Power Adapter (130W Power Delivery)). So, if I connect this docking station to my laptop's Type-C port. Then, from the docking station, I will connect the monitor for better wire management.
Another question, from which documentation on the Dell website, after entering the service tag, can I get this information? I searched many documents, but I cannot find it on the website. Can anyone help me guide how to find this?

Thunderbolt 3 was an option on this model. Most Thunderbolt ports are marked with a lightning icon and you will see a Thunderbolt controller enumerated in the device manager.
On systems without a Thunderbolt port (probably most of these), the USB-C port supports displayport over USB-C so it's capable of video just as Thunderbolt is, though with reduced bandwidth.

enter your servicetag and press "Product Specifications" to get the original shipped hard- and software config from your device.
