Display resolution table
External monitors require a certain amount of bandwidth to work properly. Monitors with higher resolution require more bandwidth.
- DisplayPort High bit rate 2 (HBR2) is DP 1.2 (5.4 Gbps maximum link rate per lane). With DP overhead and UD22 MST display bandwidth, the effective data rate is 4.25 Gbps per lane.
- DisplayPort High bit rate 3 (HBR3) is DP 1.4 (8.1 Gbps maximum link rate per lane). With DP overhead and UD22 MST display bandwidth, the effective data rate is 6.25 Gbps per lane.
- DisplayPort High bit rate 3 (HBR3) with Display Stream Compression (DSC) compression 1:2.1 ratio or higher is DP 1.4 (8.1 Gbps x 2.1 = 17.02 Gbps maximum link rate per lane). With DP overhead and UD22 MST display bandwidth, the effective data rate is 13.125 Gbps per lane.

Frequently asked questions
Some Dell docks have a power button that emulates the computers power button. This feature requires BIOS support from the computer to work. The power button emulation on the dock only works with Dell computers with BIOS support for this feature.
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.
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 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.
- Temperature triggers the fan to spin. 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 over-temperature 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 five different speeds. The dock usually works on the lowest fan speed. Put the dock in a heavy loading/high working-temperature environment and the dock fan may have a chance to work at one of the two higher speeds. This is normal, and the fan works at the various speeds depending on the work loading.
- The Dell Universal Dock UD22 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 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. It 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
- Identifiers for USB Devices
- Our Dell dock is designed to operate on AC power only. It does not support power source back on laptops (powered by laptop USB-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. This is because the dock must negotiate the proper power contract with the laptop's USB-C port and establish a laptop EC-to-dock-EC connection.
- You can disconnect and reconnect the AC Adapter from the back of the docking station to fix this.
