Use an available USB port to expand your computer's video capabilities. Featuring straightforward plug-in connectors and simple driver setup, this adapter creates a secondary VGA connection for dual monitor functionality. With two monitors, you can view a large spreadsheet over two screens, open email attachments on a separate screen, develop multiscreen presentations, or expand your graphic design workstation. Create a dual monitor configuration without buying a new computer or installing an internal video card. Not only is the adapter simple and cost-effective, it's also bus-powered so an external power cord is not required. Its compact size also makes it portable so you can use it anywhere.
