Reliable 4K Wireless HDMI Transmitter for Modern AV Systems

The Gefen GF-EXT-WiK-5G is a professional-grade 4K Wireless HDMI Transmitter built to simplify AV distribution in today’s fast-paced environments. It delivers vibrant 4K60 (4:4:4) video, USB keyboard and mouse control, and IR extension—all without HDMI cables. This makes it an ideal fit for conference rooms, classrooms, digital signage, and control centers where clean, cable-free setups are essential.

High-Performance Wireless HDMI Delivery

At its core, this 4K Wireless HDMI Transmitter uses a robust 5GHz transmission band. It supports stable, low-latency video streaming up to 50 meters (164 feet), even through standard walls. Whether transmitting to one or up to four receivers, the system maintains performance with support for HDMI 2.0 and HDCP 2.2/1.x. It’s a powerful solution for AV pros needing wireless flexibility without compromising quality.

Convenient HDMI Loop-Out and Control Signal Extension

For local content monitoring, the GF-EXT-WiK-5G includes an HDMI loop-out. This lets users view content on a nearby display while also streaming wirelessly. USB-C connectivity enables full USB KVM functionality, while IR pass-through allows remote control of connected source devices. Together, these features deliver a complete, control-enabled wireless AV solution.

Designed for Scalability and Reliable Operation

The transmitter supports up to four GF-EXT-WiK-5G-RX receivers, offering scalable deployment across different environments. With SSID pairing and channel selection, users can avoid interference from nearby AV systems. The compact metal housing, combined with plug-and-play setup, makes installation quick and easy—even in demanding professional environments.

Built for Integration and Longevity

EDID management ensures accurate communication between source and display, while firmware upgrades help futureproof the solution. Every unit ships with the necessary components: antennas, international power adapters, mounting ears, and cables—everything needed for seamless installation.
