Product Features
Technical Overview
This VGA extender utilizes twisted-pair Cat5e cabling to transmit video signals, offering a cost-effective alternative to dedicated long-run VGA cables. The system maintains signal integrity across its maximum operating distance of 262.47 feet (80 meters), with resolution support that scales based on cable length. At 150 feet (50 meters), it delivers 1920x1200 or 1600x1200 resolution, while at the full 250-foot range, it supports 1280x1024 or 1024x768 resolutions.
The extender features one VGA input on the transmitter and one VGA output on the receiver, along with two RJ-45 ports for the Cat5e connection between units. This wired connectivity ensures stable, interference-free video transmission suitable for professional installations.

FAQ
What is the maximum distance this VGA extender can cover?
The StarTech.com ST121UTPEP extender supports video transmission up to 262.47 feet (80 meters) using Category 5e or better network cabling. At this maximum distance, it maintains resolutions of 1280x1024 or 1024x768. For higher resolutions like 1920x1200, the recommended maximum distance is 150 feet (50 meters).
What video resolutions does this extender support?
This extender supports WUXGA graphics mode with a maximum resolution of 1920x1200. Resolution support varies by distance: at 150 feet (50 meters) it delivers 1920x1200 or 1600x1200, while at the full 250-foot range it maintains 1280x1024 or 1024x768 resolutions. The extender automatically adjusts to the optimal resolution based on cable length and source output.
What type of cable do I need to use with this extender?
The extender requires standard Category 5e or better twisted-pair network cabling (not included). You can use existing network infrastructure or install new Cat5e/Cat6 cable between the transmitter and receiver units. For best performance at maximum distances, we recommend high-quality, solid-core Cat5e cable rather than stranded patch cables.
Does this extender require software installation or drivers?
No, this is a pure hardware solution that requires no software, drivers, or configuration. The extender works transparently with any VGA source and display, making it compatible with computers, media players, industrial equipment, and other VGA-output devices without additional setup.
What is included in the package?
The kit includes one VGA over Cat5 transmitter, one VGA over Cat5 receiver, one installation bracket with screws, one VGA cable, one universal power adapter compatible with North American, UK, EU, and Australian outlets, and an instruction manual. Everything needed for installation is provided except for the Cat5e network cable between units.
Where can the power adapter be connected?
The included universal power adapter can be connected at either the local end (transmitter) or remote end (receiver) of the extension. This flexibility allows you to place the power source where it's most convenient for your installation, whether near the video source or near the remote display.
