Set up three monitors on the Prime Docking Station 14-in-1 with DL7400. Follow the DisplayLink driver install and connection order to avoid black screens.

Quick answer

Install the DisplayLink driver before connecting anything, then plug the dock into your laptop and add monitors one at a time. This order prevents the black-screen and detection issues that make a triple-display setup feel broken.

Why the DL7400 changes the order of operations

The Prime Docking Station (14-in-1, Triple Display, DisplayLink) with DL7400 relies on DisplayLink technology to drive multiple displays. That means your computer needs the DisplayLink driver installed before it can recognize the extra screens. If you connect monitors first, the dock may appear to work but only one or two displays will light up.

When triple display may not work as expected

DisplayLink docks work with most modern laptops, but some systems limit the number of external displays or require specific USB-C port capabilities. If your laptop already supports only one external monitor natively, the dock’s DisplayLink chip adds support, but performance may vary for tasks like gaming or video playback. For general productivity, the setup is reliable.

Step-by-step triple display setup

Download and install the DisplayLink driver: Go to the official DisplayLink website and download the latest driver for your operating system. Run the installer and restart your computer when prompted. Do not connect the dock until the installation is complete. Skipping the restart is the most common reason the driver fails to load.
Connect the dock to your laptop: Plug the dock’s USB-C cable into a USB-C port on your laptop that supports data and video. Avoid using a charging-only port. Wait for the system to recognize the dock before adding monitors. If the dock is not recognized, try a different USB-C port, preferably one marked with a display icon.
Add your first monitor: Connect one monitor to the dock using the appropriate cable (HDMI or DisplayPort). Power on the monitor and check that it appears in your display settings. This confirms the driver and dock are working. If the first monitor does not appear, reinstall the driver or try a different cable.
Add the second and third monitors: Connect the remaining monitors one at a time, checking each in display settings before adding the next. This isolates any cable or port issues. Connecting all three at once makes it harder to identify which connection is failing.
Arrange displays in your OS settings: Open your operating system’s display settings and drag the monitor icons to match their physical positions. Set the primary display and choose whether to extend or duplicate. For a triple-monitor workflow, choose Extend rather than Duplicate.
