4K 30Hz HDMI Extender Kit for Professional

This kit provides one transmitter and one receiver to extend HDMI signals over a single Cat5, Cat6 or Cat7 cable. It supports resolutions up to 4K×2K at 30 Hz and is designed for digital signage, control rooms, command centres and safety monitoring systems. The system works with off-the-shelf IGMP switches for matrix distribution.

Plug-and-Play Setup with IR Pass-Back

Installation is plug-and-play using standard Ethernet cabling up to 120 metres or 394 feet. An IR pass-back function lets you control the source device from the receiver location. Computer control software and a remote control allow input selection and switching across a scalable matrix that supports up to 100 inputs.

Sustained Operation Over IP Infrastructure

The extender transmits video and audio continuously over IP without compression artefacts during extended sessions. Point-to-point links maintain the 120-metre distance reliably. The 30 Hz refresh ceiling means the kit is not suited for applications requiring 60 Hz 4K output.

Questions about this item

How can I confirm the LKV683Matrix-4.0 is transmitting 4K video correctly after installation?

Connect a 4K source to the transmitter and a 4K display to the receiver; the receiver will show the source at up to 4K×2K@30Hz, and the IR pass-back lets you control the source from the display side to verify the link is live.

What does the kit include and what extra cabling or hardware is required?

The box contains one transmitter (TX) and one receiver (RX); you must supply Cat5, Cat6 or Cat7 Ethernet cable for the link and an off-the-shelf IGMP-capable switch if you want matrix switching beyond a single point-to-point run.

Which version of the LKV683Matrix should I choose for a 4K 30 Hz installation over 120 metres?

The LKV683Matrix-4.0 model supports 4K×2K@30Hz and reaches 120 metres over Cat6, so it matches that requirement; it does not support 4K@60Hz.
