Introduction
1
The Dell Universal Dock UD22 is a device that links all your peripheral devices to your computer using a USB Type-C cable
interface. Connecting the computer to the docking station allows you to access all peripherals (mouse, keyboard, stereo
speakers, external hard drive, and large-screen displays) without having to plug each one into the computer.
CAUTION:
Update your computer’s BIOS, graphic drivers and the Dell Universal Dock UD22 driver to the latest
versions available at www.dell.com/support BEFORE using the docking station. Older BIOS versions and drivers
could result in your computer not recognizing the docking station or not functioning optimally. Always check if
any recommended rmware is available for your docking station at www.dell.com/support.

3. Under the Multiplay displays section, modify display conguration as needed.
Display 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 eective data rate is 4.25Gbps 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 eective data rate is 6.25Gbps per lane.
• DisplayPort High Bit Rate 3 (HBR3) with DSC (Display Stream Compression) compression 1:2.1 ratio or higher is DP 1.4 (8.1
Gbpsx2.1=17.02Gbps
maximum link rate per lane). With DP overhead and UD22 MST display bandwidth, the eective data rate is 13.125Gbps per lane.

NOTE:
NOTE:
NOTE:
If higher resolution monitors are used, the graphics driver makes a judgment based on monitor specications
and display congurations. Some resolutions may not be supported and so will be removed from the Windows Display
Control Panel.
Linux operating system is unable to physically turn-o built-in display, the external display numbers will be one
less than the display numbers listed in above tables.
If the Display Port Data Rate is HBR2, then, the maximum resolution that Linux supports is 8192 x 8192 (counted with
built-in display plus external display.
Resolution support is also dependent on the monitor’s Extended Display Identication Data (EDID) resolution.
