Before connecting the docking station to your laptop and connecting a monitor and other external devices, ensure to install all the required drivers.

Connect the monitor to the docking station using the DisplayPort, HDMI, or USB-C cable provided with the monitor. The docking station supports up to 6* monitors (available on select Dell laptops only) connected simultaneously. See the Display Resolution Table below for more details about the supported resolution when connecting multiple monitors to the docking station.

To learn more about setting up and troubleshooting issues with multiple monitor setups, see these Dell knowledge base articles: How to Set up Dual Monitors or Multiple Monitors or How to Troubleshoot Multiple Monitor Issues

Display resolution table

External monitors require a certain amount of bandwidth to work properly. Monitors with higher resolution require more bandwidth.

  • HBR2 is DP 1.2 (5.4 Gbps maximum link rate per lane). With DP overhead, the effective data rate is 4.3 Gbps per lane. Laptop supports HBR2 if the DisplayPort supports DP 1.2 protocol.
  • HBR3 is DP 1.4 (8.1 Gbps maximum link rate per lane). With DP overhead, the effective data rate is 6.5 Gbps per lane. Laptop supports HBR3 if the DisplayPort supports DP 1.4 protocol.
Note: See the User Manual of your Dell laptop to identify if the DisplayPort on the laptop supports DP 1.2 or DP 1.4 protocol.

Resolution

 Minimum bandwidth required
1 x FHD (1920 x 1080) @ 60 Hz 3.2 Gbps
1 x QHD (2560 x 1440) @ 60 Hz 5.6 Gbps
1 x 4k (3840 x 2160) @ 30 Hz 6.2 Gbps
1 x 4k (3840 x 2160) @ 60 Hz 12.5 Gbps
Note: The following table only addresses the dual-cable connection situation and does not support computers that use single Type-C cable.

Note: 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).
Note: Configuration that is supported with AMD and NVIDIA in special-graphics mode. This mode is listed in the BIOS for the Dell Precision mobile workstations 7530 and 7730 requires enabling special-graphics mode when Switchable is enabled.
Dell Precision 7530 and Dell Precision 7730 with AMD Graphics only supports dual 4K@60 Hz non-HDR monitors. That is when both monitors are plugged to the two DP ports. (They are not plugged to HDMI.)
Note: HDMI and Multi-Function DisplayPort (MFDP) Type-C ports on the back of all docks in the WD19 family are toggled. HDMI and MFDP Type-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 that is 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.

Frequently asked questions

Dell Performance Docking Station WD19DC or WD19DCS works with laptops that support dual USB-C ports that support DisplayPort over USB-C. The WD19DC or WD19DCS docking station is also compatible with a laptop that has dual Thunderbolt 3 ports.

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 Thunderbolt 3.) For more information, see: Guide to USB Type-C

DisplayPort over USB-C enables the delivery of full DisplayPort AV performance. (Driving monitor resolutions of 4K and beyond.) It is SuperSpeed USB (USB 3.1) data and up to 100 W of power with the convenience of reversible plug orientation and cable direction. DisplayPort is the first AV protocol to be carried over USB-C.

To identify if the USB-C port supports DisplayPort over USB-C, look for the DisplayPort icon next to the USB-C port.

Before using the docking station, ensure that your laptop has a DisplayPort over USB-C or Thunderbolt 3 port that is designed to support the docking station.

Dell Performance Docking Station WD19DC or WD19DCS 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 that does have a dual USB-C port, you may notice limited or no functionality.

Dell Performance Docking Station WD19DC or WD19DCS provides power to the laptop over USB-C cable in the following scenarios:

Dell laptops

  • 210 W to Dell Precision mobile workstations 7000 series with 240 W AC-adapter
  • 130 W to Dell laptops (single cable plugged in) with 240 W AC-adapter

Non-Dell laptops

  • 90 W support for USB Power Delivery 3.0 (single cable plugged in)

 

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

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

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

  • The dock fan is designed with two different rotating speeds. The dock works on low fan speed. If you put the dock in a heavy loading or a high working-temperature environment, the dock 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 Performance Docking Station WD19DC or WD19DCS can charge your mobile or power bank even without being connected to the laptop. Ensure that your dock is connected to external power. The dock fan rotates automatically if the dock gets too warm. This is a 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 dock is designed to operate on AC power only, and it does not support power from a laptop. (Powered by the laptop Type-C port.) A power loss event makes all devices on the dock fail to work. Even when you restore the AC power, the dock may still not function properly because the dock must still negotiate a proper power contract with the laptop's Type-C port and establish a laptop EC-to-dock-EC connection.
