Performance in Use
The WD19TBS is Dell's Thunderbolt 3 business dock. Dock a compatible laptop and dual 4K monitors, wired network, USB devices and charging all connect with one cable.
Thunderbolt 3 gives it the bandwidth to run two 4K screens at 60Hz while keeping USB transfers quick — a step up from USB-C-only docks when you work across big spreadsheets, CAD viewers or a lot of open windows.
It suits Dell Latitude, Precision and XPS laptops with Thunderbolt 3 or 4, and also works as a USB-C dock with other laptops that support DisplayPort over USB-C, at reduced capability.
