The compact Dell Adapter - USB 3.0 to HDMI/ VGA/ Ethernet/ USB 2.0 offers a plug-and-play solution for connecting your laptop or notebook to an external display and other essential devices. The adapter also features an Ethernet port, which means it can replace as many as three dongles to save you space on your desk and in your bag. Onboard USB 2.0 means you still have an open port to connect with USB peripherals.
