What we can recommend in this scenario is that you use lower resolutions or refresh rates in order to obtain 1920 x 1080p at 60Hz on your second monitor. Note: Information taken from the reports. This may explain why you cannot set higher resolutions on the Dell Latitude 5480. In addition, please take a look at the approximate bandwidth needed to use these configurations: Since this is defined by industry standards, our recommendation is that you contact your Original Equipment Manufacturer (OEM) to obtain accurate information about the standards used by the computer/dock. To configure 2560 x 1600 60Hz, the bandwidth needed is: 7.37 Gbps approximately.īy design, bandwidth is usually shared among the devices connected to a computer or dock, limiting the number of displays you can connect to the dock/computer at the same time and the resolutions you can use.To configure 3840 x 2160 30 Hz, the bandwidth needed is: 7.46 Gbps approximately.The maximum resolution supported by the dock is either 3840 x 2160 Hz or 2560 x 1600 Dell Dock WD15 (USB Type-C) Information, Compatibility and Specifications.
