INTRODUCTION

The UHDN-4P is a dedicated multi-platform KVM
switch capable of managing four 4K computers
through a single KVM. Built with ultra-HD ready HDMI
outputs, the UHDN-4P is the first HDMI KVM switch on
the market to offer full 4K emulation at 60Hz directly
from the device. Until now, HDMI switches lost
emulated picture when disconnected from monitors,
leading to confusion and disorganization upon
reconnecting. With the UHDN-4P, full EDID-assisted
HDMI video emulation ensures visual workspaces and
screen resolutions are remembered every time.

The UHDN-4P is HDCP compliant, supporting screen
resolutions up to 4K Ultra-HD (3840x2160 @ 60Hz)
with responsive EDID emulation. Additionally, the
UHDN-4P is compatible with any USB peripheral. The
UHDN-4P is also easy to control with both a simple
front-panel interface, as well as RS-232 or hot-keys.

FEATURES

 Supports all USB 2.0 devices.
 Hot key commands for quick channel selection.
 Complete KVM emulation for error free switching.
 Easy switching via front-panel, RS-232 or hot

keys.

 Supports up to Ultra-HD 4K (3840x2160) @

30/50/60Hz.

 Supports 3D.
