120M 1080P@60Hz HDMI KVM Extender Over TCP/IP with Distance up to 120m over UTP CAT5E/6 cable

120M 1080P@60Hz HDMI KVM Extender Over TCP/IP

Model: LNK-HDE-120KVM Series

Overview

This professional HDMI KVM extender is a high-performance 120M 1080P@60Hz HDMI KVM

Extender Over TCP/IP, composed of a transmitter unit (TX) and a receiver unit (RX) that operate

as a paired system—specifically engineered for flexible, long-distance AV transmission and remote

control in commercial, educational, and professional scenarios. As a 120M 1080P@60Hz HDMI KVM

Extender Over TCP/IP, it leverages TCP/IP network protocol to break through traditional point-to-point

transmission limitations, enabling scalable signal extension for multi-display systems.

The 120M 1080P@60Hz HDMI KVM Extender Over TCP/IP supports transmission and extension of full

HD 1080p@60Hz HDMI signals via CAT5e/6 UTP (Unshielded Twisted Pair) network cables, with a maximum

stable transmission distance of up to 120 meters. Its uncompressed signal transmission ensures no loss of

image quality—preserving color accuracy and motion smoothness, which is critical for high-frame-rate applications

such as live HD video shooting or dynamic digital signage. A core advantage of this extender lies in its TCP/IP

protocol support: by connecting to an Ethernet switch, it enables point-to-multipoint signal distribution, allowing

one HDMI source to extend to multiple receivers (displays) simultaneously—greatly simplifying infrastructure for

large-scale setups and reducing wiring costs.

This extender integrates full KVM (keyboard and mouse) remote control functionality, enabling users to operate

the HDMI source device (e.g., PCs, servers, or media players) directly from the receiver end without on-site

access—enhancing efficiency in scenarios like centralized control rooms or remote lecture halls. It also features

a local loop-out function on the transmitter unit, supporting simultaneous connection of a local display (for on-site

technician monitoring) while extending the signal to remote screens, realizing both maintenance and end-user

application needs in one setup.

Equipped with built-in EDID (Extended Display Identification Data) management, the 120M 1080P@60Hz HDMI

KVM Extender Over TCP/IP automatically reads and synchronizes display parameters (resolution, refresh rate,

color depth) between the source and connected displays. This significantly improves compatibility across diverse

device brands and models, effectively avoiding common issues like signal mismatch, black screens, or frame

stuttering. Additionally, its design incorporates anti-electromagnetic interference (EMI) shielding, ensuring stable

signal transmission even in complex electrical environments (e.g., near power cables or industrial equipment).

With user-friendly plug-and-play installation (no complex network configuration required) and reliance on cost-

effective CAT5e/6 UTP cables, this extender is ideal for AV transmission in HD conference systems, professional

HD video shooting setups, HD multimedia education systems (smart classrooms, lecture halls), and HD digital

advertising/signage networks (shopping malls, airports, corporate lobbies). It combines long-distance reliability,

TCP/IP-based scalability, and multi-functional control, providing a stable, efficient, and scalable solution for

modern AV infrastructure.
