UGREEN CM455 HDMI extender

UGREEN CM455 HDMI extender extends high-definition signals reliably over long distances using existing network cabling. This 70-meter HDMI over Ethernet solution supports Full HD 1080p resolution. It uses a transmitter and receiver pair for seamless video and audio transmission in various environments.

What It Is

UGREEN CM455 HDMI extender consists of a transmitter unit and a receiver unit connected via a single Cat5e or Cat6 Ethernet cable. It converts HDMI digital signals to Ethernet-compatible format for extension up to 70 meters. The active design includes built-in chips for signal regeneration and equalization. It features HDMI 1.3 input/output with HDCP 1.4 compliance. Power adapters supply DC 5V to both units for stable operation. Aluminum or durable housing aids heat dissipation and longevity. This setup transmits uncompressed video, audio, and control signals without quality degradation over the specified distance. It supports point-to-point extension and limited cascading in some configurations.

Use Cases and Regular Users

Large homes use this extender to connect media players or set-top boxes in one room to TVs in distant living areas. Conference rooms and auditoriums link laptops or presentation devices to far projectors or displays. Classrooms extend teacher computers to hallway monitors or large screens. Retail stores deploy it for digital signage across floors or sections. Professional AV installers apply it in hotels, offices, or event venues requiring long HDMI runs without visible cables. Regular users include homeowners building multi-room entertainment systems, educators enhancing interactive lessons, business professionals managing meeting setups, and technicians handling commercial installations. Pro-level details feature support for 1080p@60Hz with full color depth, multi-channel audio formats, and EDID management for automatic display recognition. It handles 3D content, VESA DDC, hot-plug detection, and HDCP-protected sources reliably. The Ethernet cable approach reduces costs compared to long HDMI cables while maintaining signal integrity.

For network infrastructure to support such extensions, consider this D-Link Cat6 UTP cable roll.

Why It Stands Out

UGREEN CM455 HDMI extender excels in cost-effective long-distance transmission using affordable Cat5e/Cat6 cables instead of expensive long HDMI runs. Many alternatives limit distance or require multiple cables, but this model achieves reliable 70 meters at 1080p@60Hz with one network cable. Active signal processing regenerates the HDMI signal to prevent degradation, ensuring sharp visuals and synchronized multi-channel audio. HDCP compliance supports protected content from Blu-ray players or streaming devices without issues. EDID management automatically detects display capabilities for optimal resolution matching.

The included power adapters guarantee stable performance even over maximum lengths. Durable construction resists environmental factors in installed setups. Plug-and-play simplicity requires no software or complex configuration. Backward compatibility works with older HDMI sources and displays. UGREEN’s quality focus delivers better interference rejection and reliability than basic extenders, making it ideal for demanding environments like commercial AV or large homes needing unobtrusive, high-quality extensions.
