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.
