Gefen EXT-USB-2-VGA USB VGA Silver cable interface/gender adapter

EXT-USB-2-VGA Instant VGA Graphics -- without a video card or VGA interface port.
This tiny pocket-carried unit is a breakthrough in computer video technology. Now you can add a VGA video port quickly and painlessly to any computer or laptop without opening up the computer or buying expensive add-on cards! Ideal for presentations and mobile use, the Gefen USB to VGA adapter is small and lightweight, fitting in a pocket. The adapter displays full-screen, full motion video, at high-definition VGA resolutions of up to 1280x1024 @ 60 Hz with 32-bit color.
How It Works
Simply plug the device into any unused USB port on your desktop or laptop computer and install the driver software CD, and you're up and running! The USB-to-VGA device can be told to act like a second extended desktop within Windows (tm) or to simply mirror the main display.

Note: This product is compatible with all 32-bit versions of Microsoft Windows (tm).

Up to 6 USB to VGA Adapters can be used on one computer.

Mac OS X drivers are available. The latest Mac OS version supported is Snow Leopard (10.6)
