4-port, dual-video 4K/60 HDMI KVM switch 

with audio support and USB 2.0 peripheral sharing, to access and control four HDMI computers from a single USB keyboard/mouse and two HDMI monitors  

UHDN-4P-Duo is a multi-platform 4-port, dual-head HDMI KVM switch with Ultra-HD 4K/60Hz resolution video emulation. It can control keyboard-mouse functions on up to four dual-head computers, and it emulates video from 4x HDMI source devices per port. Built with four Ultra-HD ready HDMI outputs, UHDN-4P-Duo is the first dual-head HDMI KVM switch on the market to offer full 4K at 60Hz directly from the device.

UHDN-4P-Duo features EDID-assisted HDMI emulation, which ensures visual workspaces and screen resolutions are remembered every time it connects to a new system.

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

UHDN-4P-Duo is the perfect control solution for supervisors and administrators, allowing them to take command of keyboard and mouse functions on remote systems with the press of a button.

EDID pass-through and recognition
UHDN-4P-Duo 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-Duo provides quick source switching via keyboard hot keys. UHDN-4P-Duo 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.

Real-world applications
UHDN-4P-Duo excels in any professional multi-system environment, especially those where high resolution video plays a crucial role in every day workflow. Ultra-HD 4K KVM switching is a great fit in environments like server hubs, control rooms, production studios and post-production houses, transportation facilities like airports, hospitals and medical centers, and corporate IT service centers.

UHDN-4P-Duo has a broad range of applications, but the main function is to centralize the access of up to four computers with HDMI displays. Not only does it function as a KVM console, but it also supports USB 2.0 functionality. This allows users to access nearby USB devices, including those not supported by other KVM switches. UHDN-4P-Duo is the ideal solution for medical, industrial, studio and defense applications, where it is not practical or safe to have multiple CPUs in the vicinity of the workstation.
