The LNK-4KE-120KVM is a professional-grade 4K@30HZ HDMI KVM Extender 120M with Loopout,
consisting of a transmitter unit (TX) and a receiver unit (RX) that operate as a paired system—specifically
engineered to deliver ultra-high-definition (UHD) AV transmission and remote control for commercial,
educational, and professional scenarios. As a 4K@30HZ HDMI KVM Extender 120M with Loopout, it
integrates 4K video extension, KVM remote operation, and local signal loopout, making it a versatile
solution for high-end HD signal transmission needs.
This 4K@30HZ HDMI KVM Extender 120M with Loopout enables transmission and extension of
uncompressed full HD 4K@30Hz HDMI signals via CAT6/6A/7 network cables, with a maximum
transmission distance of up to 120 meters and zero signal latency. The uncompressed transmission
ensures preservation of every detail in UHD content—from fine textures in video shooting to sharp
text in digital signage—while zero latency guarantees real-time synchronization, critical for interactive
applications such as HD conference systems or live event monitoring where delay would disrupt user
experience.
A key advantage of the 4K@30HZ HDMI KVM Extender 120M with Loopout is its built-in EDID (Extended
Display Identification Data) management function. This feature automatically reads and synchronizes
display parameters (including resolution, refresh rate, and color depth) between the HDMI source (e.g.,
PCs, servers, or media players) and connected displays (monitors, projectors, or digital signage), greatly
improving compatibility across diverse device brands and models. It effectively avoids common issues like
signal mismatch, black screens, or resolution downscaling, ensuring consistent UHD performance.
The extender supports full KVM (keyboard and mouse) remote control, allowing users to operate the
HDMI source device directly from the receiver end without on-site access. This enhances operational
efficiency in scenarios such as centralized control rooms, remote lecture halls, or video editing suites,
where source equipment is often installed in dedicated equipment rooms. Additionally, it features a local
loopout function on the transmitter unit, enabling simultaneous connection of a local display (for on-site
monitoring by technicians) while extending the 4K signal to a remote screen—supporting both maintenance
and end-user needs in one setup.
With stable signal transmission (resistant to electromagnetic interference in busy electrical environments),
user-friendly plug-and-play installation (no complex configuration required), and cost-effectiveness (utilizing
existing CAT6/6A/7 wiring infrastructure), the 4K@30HZ HDMI KVM Extender 120M with Loopout is ideal for
AV transmission in HD conference systems, professional HD video shooting setups, HD multimedia education
systems (e.g., smart classrooms and lecture halls), and HD digital advertising/signage networks (shopping malls,
airports, and corporate lobbies). It combines long-distance coverage, UHD quality, and multi-functional control,
providing a stable, efficient, and cost-saving transmission solution for high-end AV infrastructure.
