The Gefen 1:4 VGA Hub (EXT-VGA-145): One VGA Input, Four VGA Outputs:

The 1:4 VGA Hub (EXT-VGA-145) allows a computer with a VGA graphic card to connect to up to four VGA compatible monitors or projectors at the same time. Because it allows one computer to drive multiple monitors for simultaneous viewing, you can use it to set up additional monitors in the workspace, or to assist presentation environments by sending graphics to both monitors and projectors at the same time.

How the Gefen EXT-VGA-145 works:

You simply connect your computer's VGA graphic port to the Gefen 1:4 VGA Hub's input using the supplied cable. Up to four analog monitors or projectors are connected to the Hub's four VGA outputs. VGA output 1 is the primary connection and is used for the main display. VGA output 2, 3 and 4 will mirror the primary connection.
