This USB to DVI/VGA Multi-Monitor External Video Adapter acts as an external video card for any USB 2. 0 laptop or desktop computer. The external video adapter converts a USB 2. 0 port into a DVI-I port - providing high quality dual display or multi-monitor capability that allows you to mirror or extend the desktop shown on the existing display as needed. For an even more versatile multi display configuration, up to five USB to DVI/VGA video adapters can be connected to the same computer simultaneously, allowing for a total of five USB connected DVI monitors to display video from a single computer. The USB to DVI/VGA External Multi Monitor Video Adapter can also be connected to VGA monitors using the included DVI to VGA adapter, and can be connected to an HDMI display using a DVI to HDMI Adapter (HDMIDVIFM - Not included).
