An issue may occur when trying to set the external monitor as the main display when it is connected to the Dell Universal (D6000 series) Dock. Only the laptop's LCD display can be set to the main display. The external monitor will not show as a choice in the Intel Graphics application. This issue was reported on the Latitude 7480 laptop with Windows 10 installed and using the integrated Intel 620 HD graphics adapter, but may appear on other Dell laptops using a similar configuration.
To resolve the issue, download and install the latest DisplayLink USB Graphics Software for Windows from the following location: DisplayLink Windows Driver Downloads. After installing the software, reboot the computer and select the external monitor as the main display in Windows display settings.
It is also recommended that you install the latest graphics driver and BIOS update for your computer from Dell Support/Drivers and downloads, under the Video and BIOS categories.
