Adding dual or multi-monitor capabilities can be easily accomplished by installing one or more USB video adapters. USB to video adapters offer the convenience of an extended desktop, and provide the benefit of referencing information independently among multiple output displays. USB to video converters can support all popular video interfaces, such as VGA, DVI and HDMI. USB graphics adapters are perfect for laptop users who don’t have the capability of adding an extra video card. It is also a cost-effective solution for desktop users who don’t want the hassles of installing an internal video card.
