Kit contents and intended use

The Lenkeng LKV383Matrix-4.0 kit contains one transmitter and one receiver for extending 1080P 60Hz HDMI signals over standard Cat5, Cat6 or Cat7 cable. It is built for installers who need to distribute video and audio to multiple displays in signage, control rooms or monitoring systems using an off-the-shelf IGMP switch.

Upgrade path and when it matters

The kit replaces direct HDMI runs limited to a few metres and adds matrix switching for up to 100 sources across a local network. The jump is worthwhile when cable lengths exceed 10 metres or when several zones must show different sources simultaneously without rewiring each display.

Sustained-load behaviour

In point-to-point mode the link reaches 120 metres or 394 feet over Cat6 while maintaining 1920x1080 at 60Hz. IR pass-back and software control remain responsive during continuous operation, and the IGMP switch handles multicast traffic without frame drops during long daily duty cycles.

Questions about this item

What cabling and distance does the LKV383Matrix-4.0 need for a point-to-point link?

Use a single Cat5, Cat6 or Cat7 cable up to 120 metres or 394 feet between the transmitter and receiver.

Which step is often missed when setting up the IR pass-back on this extender kit?

Connect the IR emitter to the TX and the IR receiver to the RX, then point the remote at the RX so commands travel back to the source.

When will the IR emitter or receiver cables on this kit typically need replacement?

Replace them if the IR control becomes unreliable or the cables show physical damage after extended use.
