UGREEN CM455 HDMI Extender – 70 m HDMI over CAT5e/CAT6 Cable

The UGREEN CM455 HDMI Extender (70 m) is a high-efficiency HDMI signal extension solution that lets you transmit high-definition video and audio from an HDMI source to displays located far away — up to 70 metres — by using a single Cat5e or Cat6 Ethernet cable. This approach eliminates the cost and complexity of long HDMI cables while maintaining sharp Full HD video quality at 1080p @ 60 Hz. Equipped with EDID management to read and optimize display resolution, EQ automatic adjustment to balance signal clarity, and HDCP 1.4 & 3D support, the CM455 helps ensure consistent playback and wide compatibility with HDMI devices. It is ideal for large rooms, AV installations, home entertainment, conference halls, classrooms, industrial displays, and more where long-distance HDMI transmission is needed.  The extender comes as a transmitter and receiver pair that you link via a network cable. With plug-and-play setup and optional external power (DC 5 V 1 A), you get reliable performance without drivers or software.
