The Dell Universal Dock (UD22) is designed for the multiuser commercial office. These offices use shared workspaces where computers across generations and manufacturers use the same dock. The design goal of the Dell Universal Dock is to provide a consistent user experience regardless of the computer or operating system used with the dock.
A dock power button provides additional functionality on Dell docks when paired with Dell laptops. However, this feature does not work with other manufacturers computers. To provide a consistent user experience with all computer users, the power button is not in any Dell Universal Dock design.
Dell Universal Dock UD22 is compatible with Dell laptops that has a USB-C port that supports DisplayPort over USB Type-C alternate mode.
USB-C also known as USB Type-C, is an industry standard connector for transmitting both data and power over a single cable. USB-C is a common type of connector with different protocols and alternate modes. Protocols like USB 2.0, USB 3.0, and alternate modes like USB Power Delivery, DisplayPort over USB Type-C can be implemented. For more information, see: Guide to USB Type-C
Before using the docking station, ensure that your laptop has a USB-C port that supports DisplayPort over USB Type-C port to support the docking station.
Dell Universal Dock UD22 is tested for specific Dell laptops. See the User Manual of the docking station to find a list of fully tested and supported Dell laptops. On non-Dell laptops, you may notice limited functionality.
Dell Universal Dock UD22 provides power to the laptop over USB-C cable: 96 W provided to the computer with a 130 W power supply connected using PowerDelivery 3.0.
