How to Use WD19, WD19DC or WD19TB Dock

The WD19 dock has three connectivity options: USB-C, dual USB-C, and Thunderbolt 3. Before installing the dock, ensure that your system is up to date and download the latest updates for the dock from Dell Support. Connect the dock's power adapter and run the firmware update. The maximum number of monitors and resolutions supported varies by model, and the rear USB-C multi-function display port and HDMI port share hardware. The rear Thunderbolt port on the WD19TB operates at USB 2.0 speeds when used with non-Thunderbolt devices.

Here's what you need to know about your WD19 dock. The WD19 is available with three connectivity options: USB-C on the WD19, dual USB-C on the WD19DC, and Thunderbolt 3 on the WD19TB.

All three models can be used with a single USB-C port, but using the WD19DC or TB in this way will reduce their ability to supply power to your system and drive multiple monitors at high resolutions.

Before installing your dock, make sure your system is up to date, as an outdated BIOS or driver may prevent your dock from functioning. You can update your system using the Dell Update, Dell Command Update, or SupportAssist tools which may be pre-installed on your PC, or by visiting dell.com/support.

Next, download the latest updates for your dock from dell.com/support. You'll need the current firmware, as well as USB audio and Ethernet drivers.

Install the drivers now, before connecting your dock. Connect your dock's power adapter. The WD19 is available with either a 130-watt adapter, which allows the dock to provide 90 watts to your system, or a 180-watt adapter, allowing charging at 130 watts.

The WD19DC provides 130 watts when connected with a single USB-C cable, and, in supported Dell systems only, 210 watts when connected with both.

Supported Dell systems also let the dock power button mirror the appearance and functionality of the system power button. For a list of supported systems, check the latest version of your dock's user guide, available at dell.com/support/manuals.

The WD19TB supplies 130 watts. Connect your dock to your system. On the WD19DC, both cable LEDs will light when supplying 210 watts, and only one when supplying 130 watts. Run the firmware update.

When complete, your dock is ready to use. When connecting monitors to your dock, the maximum number of monitors, and resolutions supported, varies by model.

Check your user guide for details. Your dock's rear USB-C multi-function display port and HDMI port share hardware. If you have a monitor connected via HDMI, the USB-C port will only provide data transfer and charging, not video.

If you connect a monitor to the USB-C port, the HDMI port is disabled. Please also note that the rear Thunderbolt port on the WD19TB operates at USB 2.0 speeds when used with non-Thunderbolt devices.

Thanks for watching.
