How It Works

The GF-EXT-DP4-HBT3 system consists of a sender and receiver pair, interconnected by a single CAT6a cable. The transmitter accepts a native DisplayPort 1.4 video signal and passes it (uncompressed) along with audio, EDID, and RS-232 control data to the receiver up to 100 meters away. By leveraging HDBaseT 3.0 technology, the entire signal chain is preserved across this distance, eliminating the need for signal boosters or additional cabling.

 

During installation, setup is streamlined through simple DIP switch configuration for EDID management and HDCP, ensuring source devices identify the display’s capabilities correctly and locking in handshake compatibility. Bi-directional Power-over-Cable further reduces clutter by enabling powered operation from either end, and RS-232 control lines allow remote device or matrix command pass-through, perfect for centralized AV control environments.

 

This robust, professional solution ensures pixel-perfect video with HDR and advanced protection standards, all inside a compact metal chassis ideal for mounting behind monitors, in server racks, or above ceilings. Field-upgradable firmware protects your investment from future compatibility issues, delivering reliability for studios, visualization suites, and high-performance installations.
