UGREEN HDMI Extender 70m – CM455

The UGREEN HDMI Extender CM455 is designed to transmit HDMI audio and video signals over longer distances using network cable. It provides a practical solution for installations where a display is positioned far from the source device.

With a transmission distance of up to 70 metres under supported conditions, this extender is suitable for conference rooms, classrooms, offices, control rooms, and commercial audiovisual systems. It helps connect computers, media players, and other HDMI sources to remote displays.

Unlike a conventional long HDMI cable, an HDMI extender uses a transmitter and receiver connected through a compatible network cable. This arrangement provides greater flexibility when routing signals through buildings and larger spaces.

Extend HDMI Signals Over Ethernet

The CM455 converts an HDMI signal for transmission over a compatible Cat5e or Cat6 network cable. The transmitter connects to the HDMI source, while the receiver connects to the remote display.

This setup can simplify cable routing through conduits, ceilings, and wall installations. It also provides a practical alternative to running a very long conventional HDMI cable.

For reliable performance across the full distance, use a good-quality, pure-copper network cable wired to the supported standard. Avoid connecting the extender through ordinary network switches or routers unless the manufacturer explicitly supports that configuration.

Full HD Video and Digital Audio

The CM455 supports Full HD 1920 × 1080 resolution at 60Hz, making it suitable for compatible monitors, televisions, and projectors. It also supports digital audio formats, including PCM and compatible multichannel audio.

Built-in EDID management helps the source and display negotiate compatible video settings. Equalization technology helps optimize the signal for the connected cable run.

The extender supports HDCP 1.4 and 3D video with compatible equipment. For technical specifications, see the UGREEN CM455 product listing.

Infrared Remote Control Support

Compatible CM455 kits can support infrared signal extension, allowing users to control a source device from the display location. This is useful when the source equipment is installed in a cabinet or another room.

The included IR accessories and their exact configuration may vary by package. Check the supplied components before planning remote-control functionality.
