StarTech.com ST121UTP VGA Video Extender over Cat5 – 500 ft, 4-Display Kit, TAA

Overview

The StarTech.com ST121UTP VGA Video Extender is designed to stretch a VGA signal farther than typical short cables, allowing you to place a source near your workspace while users elsewhere see the same content on multiple screens. With support for distances up to 150 meters (500 feet), this kit helps you design multi-display arrangements without bulky, custom cabling.

Packed as a complete solution, the kit includes a local transmitter and a remote receiver, so you can deploy a two-location setup from a single source. The local unit features one VGA input and two VGA outputs, enabling you to view the source on two displays right next to you. The remote unit brings two additional VGA outputs, giving you the freedom to display the same content on two more monitors at a distance.

Key benefits and use cases

• Extends VGA up to 500 ft (150 m) over standard Cat5 or better cable, reducing the need for long, rigid video runs.
• Two local VGA outputs enable quick duplication or split-view near the source, ideal for demonstrations, monitoring, or teaching.
• Two additional VGA outputs at the remote location open possibilities for placing displays away from the source while keeping the same content in sync.
• Economical and straightforward installation using existing Cat5 cables, with mounting brackets included for flexible placement.

Real-world scenarios

In classrooms, instructors can project to two nearby displays while extending the same content to two distant screens for improved visibility from the back of the room. In conference rooms, a single presentation source can feed multiple displays for a more immersive briefing. Retail or showroom environments can leverage the four-display setup to create engaging signage networks without reconfiguring cables or reinstalling equipment.
