Option 1 TX and 4 RX kit

  • Transmit 1080P video up to 120 metres over a single Cat6 cable
  • One transmitter drives eight receivers for simultaneous multi-display distribution
  • Extender and splitter combined in one kit for flexible installation
  • Compatible with existing Ethernet networks for easy integration
  • Designed for continuous 24‑hour operation in professional environments

Kit contents and intended use

This kit contains one transmitter and eight receivers that extend an HDMI signal up to 120 metres over a single Cat5, Cat5e or Cat6 network cable. The system supports 1080P resolution at 60 Hz and is designed for continuous 24/7 operation. It suits installers who need to distribute one HDMI source to eight displays over existing Ethernet infrastructure.

Installation notes and common issues

Each unit requires its own power supply, and the kit includes nine adapters plus a user manual. The V4.0 hardware is not compatible with LKV373 V2.0 or LKV373A V3.0 devices, so mixing generations will prevent a link. A frequent problem is using cable runs longer than 120 metres or lower-grade wiring, which causes signal loss.

Sustained-load behaviour

The extender is rated for 7x24 hour operation, meaning it maintains the 1920x1080 signal indefinitely without a cooling-down period. Performance does not degrade after the initial handshake, and the splitter function keeps all eight outputs active simultaneously. No throttling or intermittent drop-outs are specified for long-duration use.

Questions about this item

How can I confirm the LKV373A V4.0 extender kit is transmitting a 1080P signal correctly after connecting the Cat6 cables?

Check that each of the eight receivers displays a stable 1920x1080 image at 60Hz on the connected screens and verify the link LEDs on the transmitter and all receivers remain solid after power-up.

What items are included in the box and what additional cables or power units must I purchase separately?

The kit includes one V4.0 transmitter, eight V4.0 receivers, nine power supplies and a user manual; you must supply Cat5, Cat5e or Cat6 network cables for each link.

Which version of the LKV373 series should I choose if I need a 1 TX and 8 RX kit that works with my existing Cat6 runs?

Select the LKV373A V4.0 kit; it is the only version that provides one transmitter and eight receivers and is not compatible with the earlier V2.0 or V3.0 models.
