The StarTech.com ST121R is a VGA-over-Cat5 remote receiver for connecting displays to compatible ST1212T, ST1214T, or ST1218T transmitters. It suits digital signage, classrooms, and business installations that need VGA video delivered over existing Cat5 cabling, with distances up to 500 ft depending on resolution.
Recommended For
- Facilities and AV teams extending a VGA feed to a remote display over a dedicated Cat 5 UTP cable, especially where a long VGA cable run is impractical. The ST121R must be paired with a compatible ST121-series transmitter.
- Organizations maintaining VGA-based digital signage in offices, schools, or financial locations that need to distribute the same source to remote displays over existing Cat 5 cabling.
- Installers who need to feed two nearby VGA displays from one receiver location; StarTech’s manual says an ST121R can connect to two displays simultaneously.
- Teams keeping a legacy VGA display system in service that prefer a hardware extender requiring no computer drivers or software.
