INTRODUCTION
UHDN-4P Quad is a multi-platform KVM switch capable of managing four quad-head 4K computers
through a single KVM. Built with ultra-HD ready HDMI outputs, the UHDN-4P Quad offers full 4K at 60Hz
directly from the device. Until now, HDMI switches lost emulated picture when disconnected from moni-
tors, leading to confusion and disorganization upon reconnecting. With UHDN-4P Quad, full EDID-assisted
HDMI video emulation ensures visual workspaces and screen resolutions are remembered every time.
The UHDN-4P Quad is HDCP compliant, supporting screen resolutions up to 4K Ultra-HD (3840x2160 @
60Hz) with responsive EDID emulation. Additionally, the UHDN-4P Quad is USB peripheral-friendly. The
UHDN-4P Quad is also easy to control with both a simple front-panel interface, as well as RS-232 or hot-
keys.
SOURCE SWITCHING MADE EASY
The UHDN-4P Quad offers simplified management between four quad-head HDMI equipped computers’
USB 2.0 outputs. Keyboards, mice, and other connected USB devices can be switched between with
ease. This dynamic KVM switch can be controlled via hot keys or RS-232 commands, as well as directly
through the console’s easy-to-read front panel.
EDID PASS-THROUGH AND RECOGNITION
The UHDN-4P Quad features EDID Pass-Through technology and source recognition, which enables
smooth and efficient switching in virtually any scenario. This plug-and-play EDID functionality makes set
up hassle free and simple.
FULL USB KEYBOARD AND MOUSE EMULATION
The USB keyboard and mouse emulation utilized by UHDN-4P Quad provides quick source switching via
keyboard hot keys. UHDN-4P Quad simulates the presence of a keyboard and mouse for every attached
computer. This essential function simulates keyboard and mouse control for all connected computers, so
switching between each is kept seamless and completely uninterrupted.
