Microsoft Display Dock

Microsoft Display Dock is a display docking station that allows selected Windows 10 mobile devices to connect to a computer monitor, mouse, and keyboard for a desktop PC-like experience. It is also the first device to act as a dock for Windows 10 Mobile's new "Continuum" feature which allows some mobile devices to run native mobile applications as if they were desktop applications, though despite emulating Windows 10 for PCs the software doesn't have most features that come with desktop versions such as running Windows Store applications side-by-side or Win32 applications, and various applications such as Microsoft Messaging + Skype do not run in full screen mode for larger monitors.
Display dock also worked as a normal USB hub if not connected to any output source
Currently the only devices compatible with the Microsoft Display Dock are the Microsoft Lumia 950 and the Microsoft Lumia 950 XL. The dock will also work with the Microsoft Surface Go, Microsoft Surface Book 2 and other devices that support MyDP standard (also known as Mobility DisplayPort or SlimPort). However the dock's power supply is not powerful enough to charge the Surface at the same time, so the battery will slowly discharge during use unless the Surface's own power supply is also attached.
