UGREEN HDMI Extender (70m) – CM455

The UGREEN CM455 (Model 80138) is a professional-grade HDMI extender designed to transmit high-definition audio and video signals over extreme distances where standard HDMI cables fail. By utilizing a single high-quality Cat6/Cat6a/Cat7 Ethernet cable, this device reliably bridges the gap between a source device and a display up to 70 meters away.

UGREEN CM455 Key Product Features

• 70m Long-Distance Transmission: Utilizes advanced HDBaseT-like technology to extend 1080p @ 60Hz signals up to 70 meters, or 4K @ 30Hz up to 40 meters, ensuring zero signal loss over long cable runs.

• PoC (Power over Cable) Support: Features “Power over Cable” technology; only one power adapter is required to power both the Transmitter (TX) and Receiver (RX) units, significantly simplifying installation in difficult locations like ceilings or conduit-heavy areas.

• Zero Latency & Stability: Engineered for real-time transmission, making it perfect for applications where lag is unacceptable, such as security surveillance, live event broadcasting, or professional gaming.

• EDID Management: Includes intelligent EDID (Extended Display Identification Data) management, which automatically adapts to the resolution of the connected display, ensuring optimal performance without manual configuration.

• Rugged Metallic Build: The units are housed in premium metal casing, which provides superior heat dissipation and durability for 24/7 industrial or commercial operation.

UGREEN CM455 Pros and Cons

Pros

• Installation Efficiency: PoC support drastically reduces cable clutter, as you only need a power outlet at one end of the link.

• Distance Versatility: Reliable performance at long range makes it an ideal solution for large-scale professional installations.

• Stability: Hardwired Cat6 connection is significantly more reliable than wireless extenders, especially in environments with heavy signal interference.

Cons

• Cable Requirement: Requires high-quality, solid copper Cat6 or higher cable to reach the full 70m distance; standard CCA (Copper Clad Aluminum) cable is not recommended.

• Cost: As an active professional tool, it represents a higher initial investment than simple long-range HDMI cables.
