StarTech VGA Video Extender over Cat5 with Audio ST122UTPA | 150m / 500ft, 4-Display Ready

The StarTech ST122UTPA VGA Video Extender over Cat5 with Audio provides a practical, out-of-the-box solution for extending a PC’s video and audio signal to remote displays using standard Cat5e cables. Built for point-to-point digital signage, classroom, and retail deployments, it supports up to four displays (two local and two remote) from a single PC and helps keep installations clean with an included wall-mount option for the remote receiver. The system delivers reliable signal distribution over longer distances, making it easier to position displays where you need them most.

Distance and quality go hand in hand with this extender. At 1440x900, you’ll reach up to 50 meters; 1280x1024 stretches to 100 meters; and 1024x768 is supported up to 150 meters. This range makes it suitable for classroom projections, storefront windows, or conference rooms where cable routing would otherwise be cumbersome. The kit is designed to work with standard Cat5e networks, avoiding the need for special cabling while preserving the integrity of both the video and audio streams.
