Product Overview

The UGREEN HDMI Extender 70 Meters (Model CM455) is a practical solution to extend high-definition video and audio signals over long distances—ideal for home theaters, conference rooms, classrooms, digital signage, or boardrooms. It allows you to connect an HDMI source (e.g. PC, laptop, DVD player) to an HDMI display (TV, monitor, projector) located far away—up to 70 meters—without compromising signal quality.

High-Distance HDMI Signal Extension

The CM455 extends HDMI signals up to 70 meters (approx. 230 feet), enabling flexible placement of displays and source devices. This makes it ideal for scenarios where running a short HDMI cable is impractical, such as projector installations, wall-mounted TVs, or distributed AV systems.

Reliable Signal Transmission

Designed to handle full HD and high-definition video, the HDMI extender preserves HDMI video and audio fidelity over long cable runs, ensuring stable playback of movies, presentations, or live streams without signal degradation or interference.

Flexible Installation and Compatibility

The extender supports standard HDMI devices, so you can use it with TVs, monitors, projectors, media players, PCs, gaming consoles, and more. Because it uses standard HDMI input/output, it integrates easily with existing equipment—no special software or drivers required.

Durable and Practical Build

UGREEN is known for producing reliable accessories, and the CM455 is built to be sturdy enough for both home and commercial use. Its connectors and housing are designed to endure frequent plugging/unplugging, making it suitable for dynamic environments like classrooms, offices, or events.
