LENKENG LKV223P 4K @30Hz Point-to-Point HDMI Extender with PoC
Extend High-Quality 4K Video – Effortlessly and Reliably
The LKV223P turns a single HDMI source into a stable long-range HDMI connection over LAN cable – delivering crystal-clear 4K @30Hz (or 1080p @60Hz) video with zero-latency, visually-lossless transmission. Thanks to support for standard CAT6/6A/7 cabling, you can stretch your HDMI signal up to 70m (1080p) or 40m (4K) – perfect for home theatres, conference rooms, digital signage or security-monitoring setups.
Enjoy clean audio and seamless control with bi-directional IR pass-back and a built-in 3.5mm stereo audio output. The receiver also supports PoC (Power over Cable) – so only one power adapter is needed, keeping your installation neat. With added HDR10 support, EDID passthrough, HDMI loop-out (on the transmitter) and robust lightning/surge/ESD protection, the LKV223P is a turnkey solution for extending HDMI reliably over long runs – no compromise on quality or convenience.
