Designed exclusively for ultraslim HP EliteBook Notebook PCs, the HP UltraSlim Docking Station expands display, network, and device connectivity so you can be more productive throughout the day—all through a simple one-click slide-in side dock. 
Four USB 3.0 ports offer high-speed connectivity to the USB devices you use most. USB 3.0 reduces the time required for data transmission (vs. USB 2.0)1, is backward compatible with USB 2.0, and is bi-directional.
DisplayPort and VGA ports deliver legacy and future compatibility with your choice of video devices and an Ethernet/LAN port keeps you online
