What the LKV373 V2.0 extender does

The LKV373 V2.0 HDMI extender kit includes one transmitter and one receiver that send 1080p video up to 120 metres over a single Cat6 cable. It uses standard TCP/IP so multiple receivers can connect to one transmitter through a LAN router or switch. The set supports HDCP and common resolutions from 480p up to 1080p at 60 Hz, making it suitable for digital signage, conference rooms or home distribution.

Heat noise and power in normal use

The transmitter draws 3.5 W and the receiver 3 W, both powered from 5 V 1 A DC adapters. With no moving parts the units run silently, and the specified operating range of 0 to 60 °C means they stay cool inside typical rack or wall-plate installations. The compact 110 by 58 by 26 mm metal housings dissipate the low heat load without fans.

Behaviour under continuous load

Designed for 24/7 operation, the extender maintains a stable 1080p 60 Hz stream over Cat6 at the full 120 metre distance without frame drops. M-JPEG compression keeps bandwidth predictable while preserving visual quality, so long playback sessions or permanent signage loops do not degrade the link. Adding an extra Ethernet router can extend the path another 120 metres if required.

Questions about this item

How do I connect the LKV373 V2.0 TX and RX units, and which cable type gives the full 120 m reach?

Link the TX HDMI source to the TX unit, run a single Cat6 UTP/STP cable to the RX unit, then connect the RX HDMI output to the display; Cat6 achieves 120 m while Cat5e reaches 100 m and Cat5 only 80 m.

What ongoing care or part replacement should I expect for the extender set?

No user-serviceable parts are listed; keep the DC 5 V/1 A power supplies and RJ45 connections clean and ventilated within the 0–60 °C operating range, and replace only if a power adapter or cable fails.

What is the first limitation I will hit when running the extender continuously at 1080p 60 Hz?

The hard distance ceiling appears first — 120 m over Cat6, 100 m over Cat5e, 80 m over Cat5 — beyond which the 1080p 60 Hz signal will not transmit reliably.
