Description

GF-EXT-DP1-HBT3 – DisplayPort 1.2a KVM Extender over HDBaseT 3

DisplayPort HDBaseT 3.0 KVM Extender with 4K60 and Control Signals

The Gefen GF-EXT-DP1-HBT3 is a professional-grade DisplayPort 1.2a HDBaseT 3.0 KVM Extender designed to transmit uncompressed 4K60 DisplayPort 1.2a video, USB control, audio, and RS-232 signals up to 100 meters over a single CAT6A cable. Built for integrators and system designers, this solution is ideal for legacy DisplayPort environments that demand high-performance signal extension with streamlined cabling.

4K60 Video and Legacy DisplayPort Compatibility

As a robust DisplayPort 1.2a HDBaseT 3.0 KVM Extender, the GF-EXT-DP1-HBT3 supports 4K60 (4:4:4) resolution with HDR passthrough. It delivers pixel-perfect performance without latency or compression. This makes it ideal for applications such as command centers, education, healthcare, and commercial displays that still utilize DisplayPort 1.2a infrastructure.

USB KVM and Bidirectional RS-232 Extension

Incorporating full USB 2.0 functionality, this KVM extender over HDBaseT supports remote keyboard, mouse, and peripheral operation. It includes two USB-A and one USB-C port on the Receiver for flexible endpoint connectivity. Bidirectional RS-232 ensures remote device control, while HDCP 2.3 compliance and EDID management provide seamless communication between source and display.

USB, Audio, and Control Integration for Pro-Grade Flexibility

Beyond video, the DisplayPort HDBaseT 3.0 KVM Extender supports full USB 2.0 pass-through, enabling seamless KVM functionality for remote desktop control. The system features a USB-C host port on the transmitter and multiple USB-A and USB-C ports on the receiver, supporting HID devices and bulk transfers. Bidirectional RS-232 and Ethernet ensure full compatibility with control systems and IP-based network environments.

Flexible Audio Support and Gigabit Ethernet

The system supports multichannel embedded audio and stereo analog audio de-embedding for integration into professional AV environments. Gigabit Ethernet passthrough enables connected devices or remote management systems. Whether used in a networked AV system or standalone extension, this DisplayPort HDBaseT 3.0 KVM Extender ensures reliability and flexibility.

Installation Efficiency with Power over HDBaseT

PoH simplifies power requirements by allowing either the Transmitter or Receiver to power the system. Compact metal enclosures with locking power supplies and rack-mount kits make it easy to deploy in commercial installations. This extender is ideal for legacy DisplayPort environments needing long-range digital signal extension.
