Black transmitter and four receivers in a 1 TX 4 RX kit

Lenkeng Technology Co,. Ltd

Lenkeng Technology Co,. Ltd LKV373 V2.0 HDMI Extender Kit 1 TX 4 RX

SKU CH-GJV9-ZBFG6

HDMI extender kit with one transmitter and four receivers sends 1080p video up to 120 metres over Cat6 cable

Option 1 TX and 4 RX kit

  • One transmitter drives four receivers over Cat5e/6
  • 1080p 60 Hz video reaches 120 m on Cat6
  • M-JPEG compression keeps picture quality near-lossless
  • Extra router hop adds another 120 m of reach
  • Compact 110 × 58 × 26 mm units run 24/7

Kit Composition

This Lenkeng kit contains one transmitter and four receivers so a single HDMI source can feed up to four displays. It is built for installers who need to distribute 1080p video to multiple rooms over standard network cabling. The set works with set-top boxes, media players and game consoles that output HDCP-protected signals. No additional capture hardware is required for basic point-to-multipoint distribution.

Operating Conditions

Units are rated for continuous 24-hour operation in ambient temperatures from 0 to 60 degrees Celsius. The transmitter draws 3.5 watts and each receiver draws 3 watts from the supplied 5-volt 1-amp adapters. Signal travels up to 120 metres over Cat6, 100 metres over Cat5e and 80 metres over Cat5 without active cooling or audible fans. M-JPEG compression keeps latency low while preserving visible image quality.

Sustained Load Behaviour

Under non-stop use the extender maintains the full 1080p 60 Hz resolution list including 720p and 1080i variants across all four outputs. Adding a standard Ethernet router extends the reach by another 120 metres per hop without introducing frame drops. The TCP/IP transport layer handles switching and splitting duties so bandwidth remains stable during prolonged sessions. Heat stays within the specified envelope because power draw per unit never exceeds 3.5 watts.

Questions about this item

How do I connect the single transmitter to four receivers using a network switch?

Connect the transmitter HDMI source, then run Cat5e or Cat6 cables from the transmitter RJ45 port to a LAN switch, and from the switch to each receiver RJ45 port; all four receivers will display the same 1080p signal.

What power supplies need checking after years of continuous 24-hour operation?

The transmitter uses a DC 5V/1A adapter drawing 3.5W and each receiver draws 3W; verify all five adapters maintain stable voltage if the system runs 7x24 hours.

At what cable length does 1080p 60Hz transmission become unreliable on Cat5e?

The kit guarantees 1080p 60Hz up to 100 metres over Cat5e; beyond that distance signal integrity drops, so use Cat6 for runs up to 120 metres.
