Thunderbolt Configuration

If Dell BIOS is used in your computer, you may find the below Control options on the Thunderbolt Configuration page in your BIOS Setup:

  1. Enable Thunderbolt Technology Support (Enabled by default)
    • When enabled, the Thunderbolt Technology feature and associated ports and adapters are enabled.
    • When disabled, the Thunderbolt Technology feature is disabled, and any connected Thunderbolt adapter devices are not available in preboot or within the operating system.
  2. Enable Thunderbolt Boot Support (Disabled by default)
    • When enabled, the following Thunderbolt adapter features are enabled during Preboot: Adapter boot support for Thunderbolt and the USB device on Thunderbolt adapter support. (Includes USB boot support.) This allows Thunderbolt adapter peripheral devices and USB devices that are connected to the Thunderbolt adapter to be used during BIOS preboot. However, setting this to "Enabled" overrides the Security Levels used within the operating system. When this setting is enabled, any Thunderbolt adapter peripherals and USB devices that are connected to the Thunderbolt adapter port before booting the computer can be used in preboot. As long as the device remains connected, it continues to function within the operating system, regardless of the Security Level set in the BIOS.
  3. Enable Thunderbolt Adapter Preboot Modules (Disabled by default)
    • When enabled, this setting allows PCIe devices that are connected through a Thunderbolt adapter (that is PCIe devices behind the Thunderbolt adapter) to perform the PCIe device’s UEFI Option ROMs (if present) during preboot.
    • When disabled, this setting prevents PCIe device Option ROMs from running during preboot for PCIe devices that are connected behind the Thunderbolt adapter.
NOTE: The following options may allow devices that are connected to the Thunderbolt adapter during preboot to function in the operating system. (Enabling the "Enable Thunderbolt Adapter Boot Support" or "Enable Thunderbolt Adapter Preboot Modules.") This is regardless of the Security Level selected in BIOS Setup. The device continues to operate in the operating system until it is disconnected. When reconnected while within the operating system, the device connects according to the Security Level and previous operating system authorizations.

Thunderbolt Security

The settings below configure the Thunderbolt adapter security settings within the operating system. Security Levels are not applicable or enforced in the Preboot environment.

  • No Security: Automatically connect to devices plugged into the Thunderbolt port.
  • User Authorization: Approval is required for any new devices that are connected to the Thunderbolt port.
  • Secure Connect: The Thunderbolt adapter port allows connection to devices that have been configured with a shared key.
  • DisplayPort Only: Automatically connect to DisplayPort devices only. No Thunderbolt adapter or PCIe devices are allowed to connect.

In the BIOS of a Dell Thunderbolt-enabled laptop, you can configure the security settings of the Thunderbolt connection. You can find the configuration options in the BIOS path: System Configuration > USB/Thunderbolt Configuration

  • No security - Allow legacy Thunderbolt devices to autoconnect - the CM auto connects a new device plugged in.
  • User Authorization - Allow User Notification devices at a minimum - the CM requests connection approval from the host SW and autoapproval may be given based on the Unique ID of the connecting device.
  • Secure Connect - Allow one-time saved key devices at a minimum - the CM requests connection approval from the host SW and autoapproval is only given if the host challenge to the device is acceptable.
  • DisplayPort Only - Allow DisplayPort sinks to be connected (re-driver or DP tunnel, no PCIe tunneling)

Microsoft Windows operating system includes the VGA graphics drivers only. For optimum graphics performance, install the latest Dell graphics drivers for your laptop from the Dell Drivers & Downloads website under the "Video" section.

NOTES: Linux operating system is unable to physically turn off integrated display. The external display numbers are one less than the display numbers listed in the above tables.
If the Display Port Data Rate is HBR2 then the maximum resolution that Linux supports is 8192 x 8192 (counted with integrated display plus external display).
WD19TB for Thunderbolt computers with HBR2:
  1. If the integrated display resolution is FHD (1920 x 1080 @ 60 Hz), two external displays with QHD (2560 x 1440) @ 60 Hz could be supported.
  2. If the integrated display resolution is 4K (3840 x 2160 @ 60 Hz), only one external display with QHD (2560 x 1440) @ 60 Hz could be supported.
NOTE: *Configuration that is supported with AMD and NVIDIA in discrete-only mode or special-graphics mode. These modes are listed in the BIOS for the Dell Precision mobile workstations 7000 series. They require disabling switchable graphics for discrete-only mode or enabling special-graphics mode when Switchable is enabled. If the laptop does not have these options in the BIOS, then four monitors are not supported.
NOTE: **HBR3 x2 lanes - 12.9GPS is only applicable to computers that are DP1.4 over Thunderbolt 3, currently this means the Dell Precision 7540 and 7740.
NOTE: HDMI and Multi-Function DisplayPort (MFDP) USB-C ports on the back of all docks in the WD19 family are toggled. HDMI and MFDP USB-C cannot support dual monitors simultaneously. Only one of these ports can be used as a display device at a time.
NOTE: If higher resolution monitors are used, the Graphics driver makes a judgment based on monitor specifications and display configurations. Some resolutions may not be supported and is removed from the Intel Graphics Media Control Panel.
Resolution support is also dependent on the monitor’s Extended Display Identification Data (EDID) resolution.
NOTE:
5K resolution support is only available in either of these conditions:
  • With discrete graphics mode only, or special graphics mode, or
  • Using the Thunderbolt 3 Type-C to a dual DisplayPort adapter
NOTE: The XPS 7390 2-in-1, XPS 9300, XPS 9310, and XPS 9310 2-in-1 do not support 4K at 60Hz through the docking station WD19. The solution is to connect the external monitor directly to the computer.

Dell Thunderbolt Docking Station WD19TB and WD19TBS are compatible with Dell laptops that have a USB-C port that supports Frequently Asked Questions (FAQs) About the Thunderbolt Port on a Dell Computer. The WD19TB and WD19TBS dock works as a WD19 docking station on Dell laptops that has a USB-C port that supports DisplayPort over USB-C alternate mode.

NOTE: To learn more about what type of USB-C port is available on your laptop, see the User Guide of the laptop.

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. Different protocols can be implemented. (For example: USB 2.0, USB 3.0, alternate modes like USB Power Delivery, DisplayPort over USB-C and Frequently Asked Questions (FAQs) About the Thunderbolt Port on a Dell Computer.) For more information, see: Guide to USB Type-C

Thunderbolt (previously called Light Peak) is a hardware interface that combines data, video, audio, and power in a single connection. Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into one serial signal and also provides DC power, all in one cable. While Thunderbolt 1 and Thunderbolt 2 use the same connector as mini-DP (DisplayPort) to connect to peripherals, Frequently Asked Questions (FAQs) About the Thunderbolt Port on a Dell Computer uses a USB-C connector.

Dell Thunderbolt Docking Station WD19TB and WD19TBS are 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 Thunderbolt Docking Station WD19TB and WD19TBS provide power to the laptop over a USB-C cable in the following scenarios:

For Dell laptops

  • 130 W with Dell laptops and 180 W power supply

For non-Dell laptops

  • 90 W with non-Dell laptops and power supply

  • Temperature triggers the fan. The docking station fan does not rotate until the docking station is hot enough to trigger a thermal threshold.
  • Conversely, if your docking station is not cool enough, the fan does not stop even when you disconnect the docking station from the laptop.

  • When you hear a loud fan noise, it is warning you that the docking station is in some kind of hot condition. For example, the vent in the docking station may be blocked or the docking station is working in a high working-temperature environment (> 35C). Eliminate these abnormal conditions from the docking station. If you do not eliminate the abnormal condition, in a worst-case situation, the docking station shuts down through the overtemperature protection mechanism. Once this happens, unplug the USB-C cable from the laptop and remove the docking station’s power adapter. Then, plug in the power adapter to recover the docking station back online.

  • This is a normal condition. The first time plugging in the docking station’s AC adapter triggers the fan to rotate, but it turns off soon.

  • The docking station fan is designed with two different rotation speeds. The docking station works on low fan speed. If you put the docking station in a heavy loading or a high working-temperature environment, the docking station fan may have a chance to work at a high speed. But, this is normal and the fan works at a low/high speed depending on the work loading.

  • The Dell Thunderbolt Docking Station WD19TB and WD19TBS can charge your mobile or power bank even without being connected to the laptop. Ensure that your docking station is connected to external power. The docking station fan rotates automatically if the docking station gets too warm. This is the normal working condition.

  • When a new device is plugged in, the USB hub driver notifies the Plug and Play manager that a new device was detected. The plug and play manager queries the hub driver for all the device's hardware IDs and then notifies the Windows operating system that a new device must be installed. In this scenario, the user sees a hardware installation window.
  • Step 1: The New Device is Identified This hyperlink is taking you to a website outside of Dell Technologies.
  • Identifiers for USB Devices This hyperlink is taking you to a website outside of Dell Technologies.

  • Our Dell docking station is designed to operate on AC power only, and the laptop cannot power it. A power loss event makes all devices on the docking station fail to work. Even when you restore the AC power, the docking station may still not function properly because the docking station must still negotiate a proper power contract with the laptop's USB-C port and establish a laptop EC-to-dock-EC connection.
