Connecting a supported laptop to the Dell UD22 docking station, gain access to all your peripherals without having to plug each device into the laptop. (For example: Peripherals such as the mouse, keyboard, stereo speakers, external hard drive, and large-screen monitor.)
NOTE: Dell Dual Charging Docking Station HD22Q is compatible with Dell laptops with a USB-C port. The HD22Q docking station has a USB Type-C port that supports DisplayPort over USB Type-C alternate mode.
For help with specifications, setup, connecting an external monitor, troubleshooting common issues, and so on, see the appropriate expanding section below.

- * The third and fourth displays must be daisy-chained through the DisplayPort (DP) 1.4 port using Multi-Stream Transport (MST) monitors connected to the DP 1.4 port. All DP-connected monitors should have DSC support. If non-DSC monitors are used, then the maximum resolution (HD: 1280 x 720) is the same as HBR3 non-DSC (12.9Gbps) offerings per lane). With DP overhead and HD22Q MST display bandwidth, the effective data rate is 4.25 Gbps per lane.
- ** This resolution is supported when using an HDMI 2.1 monitor with Fixed Rate Link support for a higher video resolution and refresh rate. An HDMI 2.1 cable is also required for this display resolution.
- *** Quad display setup functions only when the laptop LCD is off.
NOTE: If higher resolution monitors are used, the graphics driver makes a judgment based on the monitor specifications and display configurations. Some resolutions are not supported and are removed from the Windows Display Control Panel.
NOTE: The Linux operating system is unable to physically turn off the integrated display. The external display numbers are one less than the display numbers listed in the above table.
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.)
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: Resolution support is also dependent on the monitor’s Extended Display Identification Data (EDID) resolution.

Additional Information
Frequently asked questions
If the battery gets too warm, the device might limit charging and resumes charging once the temperature drops. Try to move the device and Qi charger to a cooler location.
Find a position that works best for the device to charge. Check by placing the device in the portrait position or upside-down, or landscape position. The wireless charge LED illuminates Solid White, while transmitting power to the wireless charging device.
Only one device can be charged at a time. Multiple coils do not increase the charging power. The use of coil arrays is primarily in the interests of convenience and efficiency improvement rather than overall power delivery.
Try repositioning the device.
Try removing the case.
During wireless charging, the back of the phone cannot have any attached iron, metal, coins, Integrated Circuit (IC) Cards, bank cards, or magnetic or metal objects.
- When a new device is plugged in, the USB hub driver notifies the Plug and Play (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.

- Our Dell dock is designed to operate on AC power only, and it does not support a laptop power source back to the dock. (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 because the dock must negotiate a 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.
