Do I need to install software in order to use the device?
Yes, DisplayLink software is required for the UD-3900PDZ for full functionality. Manual installation is required for macOS, Windows installation is typically automatic. We recommend installing the latest DisplayLink software for the best performance.
When installing DisplayLink software on my Mac, why is it necessary to grant ‘Screen Recording’ permission?
macOS requires “Screen Recording” for DisplayLink to send display data over USB. No data is saved or recorded. Without DisplayLink, only the Alt Mode HDMI port works. IT-managed systems may need admin approval to install drivers.
Does this dock allow for three displays even on base Apple M-Series Macs?
Yes. Enabled by DisplayLink technology, UD-3900PDZ can connect three displays even if the computer supports only one display output on its own. DisplayLink Manager installation required on Mac.
Which USB-C port on the dock can be used to connect my computer?
The USB-C port on the rear of the dock is dedicated for connecting your laptop. The front port is a hub port only, so it doesn’t work to connect a computer to the dock.
Why aren’t all three displays connecting to my dock?
Please confirm your laptop’s USB-C port supports video output (Alt mode), that the docking station is connected to the computer with the USB-C data cable provided with this dock, and that you have the DisplayLink driver/software installed.
