The StarTech ST121HDBT20L is an HDMI over CAT6 extender designed to transmit high-fidelity video and audio signals over long distances without signal degradation. This device is critical for digital signage, conference rooms, and command centers where the source device must be located away from the display. It supports 4K resolution at 60Hz up to 70 meters and 1080p at 60Hz up to 100 meters, ensuring crisp visuals for demanding applications. The ST121HDBT20L leverages standard CAT5e or CAT6 cabling, simplifying installation and reducing costs compared to proprietary solutions.
This extender is compatible with any HDMI 2.0 source device and display. It requires CAT5e or CAT6 Ethernet cabling for signal transmission. The unit supports 4:4:4 chroma subsampling for pristine color reproduction and 7.1 surround sound audio, making it suitable for professional AV installations. It operates with a 100-240V AC input and provides 18V DC output via the included power adapter, consuming a maximum of 18 Watts.
For optimal performance, use CAT6 cabling for distances up to 100 meters (328 ft.) for 1080p or up to 70 meters (230 ft.) for 4K 60Hz signals. CAT5e can be used but may limit the maximum achievable distance, especially at higher resolutions. Ensure all connections are secure to prevent signal loss. The operating temperature range is 0°C to 40°C (32°F to 104°F).
