The StarTech ST121UTP VGA Video Extender allows you to connect up to four (two local and two remote) monitors from a single PC or other source. The VGA video signal is transmitted to remote monitors through standard four-pair Category 5e UTP cable (terminated with RJ45 connectors). The VGA video extender over Cat5 extends the connection distance between the VGA source and the display by 500 feet. It comes with a local transmitter and a remote receiver unit, which helps when remote monitor displays are required. The VGA Cat5 extender features one VGA input port and two VGA output ports that let you split a single VGA signal into two separate displays.
