Startech ST121UTP Description

Startech ST121UTP VGA Video Extender over Cat5 allows you to extend your VGA video signal by up to 150 meters (500 feet) and connect up to 4 displays (2 local and 2 remote) from that single source.

The included a mounting bracket for the ST121UTP receiver provides versatile mounting options such as a wall, desk or cabinet.
