If using a docking station, remove all other devices that may be connected to the dock and try again.This will ensure that the device is receiving enough power from the USB bus.

The DL-3000 family implements monitor detection and the DisplayLink UI will only be shown in the system tray when a DisplayLink device and a display is detected. If you have a product based on the DL-3xxx or DL-5xxx (USB 3.0) family, the DisplayLink UI will only appear if a DisplayLink device has been detected AND a monitor is connected to the video output. If you do not see the DisplayLink UI in the system tray, check that the device is recognised on the USB bus. The UI icon will always appear in the system tray if you are running Windows 10 Anniversary update 2016, released August 2016. Note: Unless a DisplayLink product is identified by the DisplayLink software on the USB bus, the DisplayLink UI icon will not appear in the Windows system tray (v7.9 or earlier software), or will show the DisplayLink "disconnected" icon (8.0 software onwards). If your DisplayLink product does not work, has stopped working, or has never worked, follow the steps below to try and diagnose if it is a hardware problem. ![]()
