DisplayPort KVM HDBaseT 3.0 Extender with 4K@60Hz & USB Support (GF-EXT-DPK-HBT3)

Remote workflows shouldn't mean reduced performance. The Gefen GF-EXT-DPK-HBT3 brings workstation-grade visuals and responsive control together over a single CAT6a cable, extending 4K@60Hz DisplayPort 1.2a video along with USB 2.0 KVM, Ethernet, audio, and control signals up to 100 meters (330 feet). Built on HDBaseT 3.0 with HDR10, Dolby Vision, and HLG support, it delivers brilliant color depth and clarity, making it ideal for creative suites and control centers where precision matters. PoH+ power enables single-end PSU operation, while bi-directional RS-232 and IR control ensure seamless system integration. Engineered for plug-and-play reliability and zero-latency control, it keeps your visuals and commands in perfect sync, no matter the distance.

Key Features

Reference-Grade 4K Extension: Extends 4K@60Hz 4:4:4 DisplayPort video and USB KVM up to 100 m over a single CAT6a cable, built on HDBaseT 3.0.

 

HDR10, Dolby Vision, and HLG Support: Delivers brilliant color depth and clarity, making it ideal for creative suites and control centers where precision matters.

 

Remote Operation with Local Responsiveness: Designed for operators who need workstation-level control hundreds of feet away, without perceptible latency.

 

Optimized Signal Architecture: Independent clock domains and link training ensure steady synchronization across video, audio, and USB pathways.

 

Studio-Grade Audio Transport: Supports full-bandwidth LPCM and lossless bitstreams for accurate monitoring and post-production workflows.

 

Interoperable Connectivity: Ethernet, RS-232, and IR pass-throughs allow system-wide communication with control systems or automation software.

 

Installer-Centric Design: DIP-configurable modes, status LEDs, and PoH+ simplify setup, verification, and long-term maintenance. Plug-and-play setup with front-panel indicators; PoH+ power enables single-end PSU operation.

How It Works

The Gefen GF-EXT-DPK-HBT3 is built on HDBaseT 3.0 and extends 4K@60Hz 4:4:4 DisplayPort 1.2a video along with USB 2.0 KVM, Ethernet, audio, and control signals up to 100 meters (330 feet) over a single CAT6a cable. Consolidating video, USB, audio, and control onto one cable run keeps workstation-grade visuals and responsive control together, even when the source and the operator sit hundreds of feet apart.

 

PoH+ power enables single-end PSU operation, simplifying installation by removing the need for power at both ends of the link. Integrations are handled in-line as well: bi-directional RS-232 and IR control ensure seamless system integration, while Ethernet, RS-232, and IR pass-throughs allow system-wide communication with control systems or automation software.

 

Signal integrity is maintained by independent clock domains and link training, which ensure steady synchronization across video, audio, and USB pathways. Audio is carried with full-bandwidth LPCM and lossless bitstreams for accurate monitoring and post-production workflows. Engineered for plug-and-play reliability and zero-latency control, the GF-EXT-DPK-HBT3 keeps your visuals and commands in perfect sync, no matter the distance.
