4K HDMI Extender Over Cat5e/Cat6 Up to 328 ft - Reliable 4K@30Hz

In this review of the 4K HDMI Extender over Cat5e/Cat6, the bottom line is straightforward: it is for installers and AV users who need long-distance, low-latency 4K video and audio distribution with simple wiring. The extender's single biggest strength is lossless 4K@30Hz transmission over ordinary Ethernet cable up to 328 ft when using Cat6 or Cat7, making it a practical choice for conference rooms, houses of worship, and home theater setups that require clear, synchronized audio and video without complex configuration.

Key Features

• 4K@30Hz support: Delivers up to 3840x2160@30Hz for crisp high-definition video on compatible displays.
• Long-range transmission: Extends HDMI over Cat6/7 up to 328 ft (100 m), and over Cat5e up to 262 ft (80 m), reducing the need for multiple signal repeaters.
• Lossless AV: Uses oxygen-free copper cable to provide smooth, stable picture quality with audio-video synchronization and minimal latency.
• POC power delivery: Power over cable means the receiver can run from the transmitter supply, simplifying wiring and avoiding extra outlets at the display.
• EDID management: Copies and stores EDID information on the sender side to improve compatibility with different sources and displays.
• Wide compatibility: Works with laptops, set-top boxes, projectors, surveillance systems and most HDMI devices used in AV installs.

Who It's For

This unit is aimed at AV integrators, IT teams, and event technicians who need to move high-resolution HDMI signals across medium to long runs without running fiber or multiple extenders. It is also well suited for permanent installs in conference rooms, lecture halls, small churches, and residential home theater where a single transmitter can power the receiver via POC.

Casual users with only short cable runs or those who require 4K at 60Hz should look elsewhere, since this extender is optimized for 4K@30Hz performance and longer distances rather than maximum frame-rate gaming or ultra-high refresh needs.

Pros & Cons

Pros

• Reliable long-distance 4K delivery over common Cat cables, reducing complexity in multi-room installs.
• POC plug-and-play operation simplifies wiring and removes the need for a dedicated power outlet at the receiver.
• EDID management improves compatibility with different displays and source devices in mixed environments.
• Lossless transmission yields clear, distortion-free video and synchronized audio suitable for presentations and video feeds.

Cons

• Maximum resolution is 4K@30Hz, so it is not ideal for 4K@60Hz or high refresh-rate gaming scenarios.
• Performance depends on cable quality; to reach the full 328 ft range a high-performance Cat6/7 cable is recommended.

Our Verdict

The 4K HDMI Extender over Cat5e/Cat6 is a pragmatic, cost-effective solution for AV installs that require reliable long-distance 4K@30Hz distribution with simple wiring. Installers will appreciate the POC convenience and EDID handling, and the extender represents good value for conference rooms, houses of worship, and multimedia displays where 4K@30Hz is sufficient.

Frequently Asked Questions

Can the receiver be powered through the Ethernet cable?
Yes. The extender uses POC so the transmitter supplies power to the receiver via the Cat cable, and only one power adapter is normally required.

What cable is recommended to reach the full 328 ft range?
High-performance Cat6 or Cat7 cable with oxygen-free copper conductors is recommended to achieve the 328 ft (100 m) maximum distance.

Does it support EDID for compatibility with different displays?
Yes. The device supports EDID management and can copy the monitor's EDID to the sender side to improve compatibility with various source and display devices.
