HDMI 2.1 Extender with HDBaseT & 8K/30Hz Support (GF - EXT - HD - HBT) - GF-EXT-HD-HBT - Gefen

Key Features

Next-Level Visual Fidelity: Purpose-built for 8K workflows in medical imaging, simulation, and high-end home cinema environments where perfectly preserved visual data is critical.

High-Bandwidth Endurance: Capable of handling up to 40 Gbps of video throughput using visually lossless compression, guaranteeing the exact signal sent from the source reaches the display intact.

Intelligent Power and Thermal Control: Constructed with efficient internal components and a precision-engineered enclosure to prevent signal degradation resulting from heat buildup.

Installation Agility: Features a local HDMI loop-out on the transmitter base, allowing for instant, real-time signal verification during complex commissioning or live events.

Eco-Minded Construction: Environmentally conscious design, packaged with recyclable materials, and engineered for exceptionally low idle power draw without sacrificing operational performance.

How It Works

Deploying the Gefen GF-EXT-HD-HBT provides an immediate, robust upgrade to any professional video routing system. Simply connect your HDMI source to the Transmitter (TX) and your display to the Receiver (RX). A single CAT5e/6/6a cable bridges the two units, sending visually lossless ultra-high-definition video across standard cabling infrastructures. System integration is further streamlined via Power over Cable (PoC), requiring only a single power supply to drive both the transmitter and receiver. Integrated RS-232, bi-directional IR ports, and built-in EDID management give installers ultimate control and signal verification flexibility directly from the equipment rack.
