The USBVGADOCK2 is a combination USB VGA adapter and 4-in-1 docking station that converts a single USB 2.0 port into multiple connection ports, including: a VGA port, 10/100 RJ45 network connection, dual (3.5mm phono) audio ports and four additional USB 2.0 ports. Compatible with a broad range of operating systems, including Microsoft Windows 7, the USB VGA adapter/docking station supports 1600x1200 (32-bit) display resolutions for connected VGA monitors and saves the time and hassle of having to disconnect devices like speakers and USB peripherals (scanners, printers, webcams etc.) in order to re-connect them to another computer.Using this convenient docking station makes it as simple as creating the single USB 2.0 host connection in order to access the connected peripherals.
