USB-C KVM Extender over HDBaseT 3.0 – GF-EXT-UCK-HBT3

USB-C KVM Extender over HDBaseT 3.0: Built for Modern Workspaces

The Gefen GF-EXT-UCK-HBT3 USB-C KVM extender delivers advanced performance for professional AV environments. It combines 4K60 4:4:4 video, USB 2.0, stereo audio, and 60W charging through a single CAT6A cable. This compact solution streamlines installations by reducing cable clutter while enhancing signal reliability and user experience.

Optimized for USB-C AV Extension

Supporting DisplayPort Alt Mode, the GF-EXT-UCK-HBT3 allows modern laptops, tablets, and devices to connect directly via USB-C. It extends signals up to 130 feet (40 meters) using HDBaseT 3.0 while maintaining uncompressed video quality. This makes it an ideal solution for meeting rooms, education settings, and hybrid workspaces where performance and simplicity matter.

Reliable Signal, Seamless Integration

EDID pass-through and HDCP 2.3 compliance ensure clean communication between source and display. These features minimize setup issues, eliminate compatibility errors, and enable worry-free integration. The extender’s USB 2.0 functionality supports remote KVM for peripheral control—including keyboard, mouse, and touchscreen input.

Power, Performance, and Practicality

The GF-EXT-UCK-HBT3 delivers up to 60W of USB-C charging power, eliminating the need for additional chargers. PoC (Power over Cable) support further simplifies installation by reducing the number of required power sources. Users benefit from a streamlined setup with fewer devices and cleaner cable management.

Designed for Flexibility

Compact and mount-friendly, the extender fits behind monitors or inside equipment racks for clean, professional installs. Whether deployed in small conference rooms or large AV networks, it enables smooth, intuitive workstation control with minimal setup time.
