Professional HDMI 1.4 Extender Kit

This Lenkeng LKV683-4.0 kit sends 4Kx2K@30Hz video and audio up to 120 metres over a single CAT5e or CAT6 cable. The transmitter and receiver pair includes IR passback so the source device can be controlled from the display location. HDCP 1.4 compliance protects premium content during transmission.

Installers needing long-range 4K@30Hz distribution

Suits integrators who want to use existing structured cabling and standard network switches to split the signal to multiple zones. Not for buyers who require 4K@60Hz, HDR, HDCP 2.2 or HDMI 2.0 features. Not for runs that exceed the stated 120 metre reach.

Maximum reach of 120 metres at 4Kx2K@30Hz

The single specification that decides fit is the 120 metre extension distance at the full 4Kx2K@30Hz resolution. Shorter runs work at the same resolution; longer runs or higher frame rates are outside the device capability.

Questions about this item

Should I choose the single transmitter and receiver kit or add extra receivers for multiple displays?

The base kit includes one transmitter and one receiver; additional receivers can be added by connecting the extender to a router, which allows unlimited splitting and extension without affecting the existing network.

What does the 4Kx2K@30Hz rating mean when the extender is installed in a real system?

It means the extender can pass video at up to 4Kx2K resolution at 30 frames per second over a single CAT5e or CAT6 cable for distances up to 120 metres or 394 feet.

How does the HDMI 1.4 and HDCP 1.4 interface limit what I can actually send through the extender?

The extender is compatible with HDMI 1.4 and HDCP 1.4, so it will transport signals that conform to those standards, including IR control signals in the 20 kHz to 60 kHz range.
