Product Datasheet

Multi-tasking is part and parcel of running a small business. There are a range of solutions available to you to help you function more effectively. For example, the Smart AVI UHDN-4P-Duo is a 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 remote computers, and emulates video from HDMI source devices.

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

Better still, the UHDN-4P-Duo is the first dual-head KVM switch on the market to offer full Ultra-HD 4K emulation at 60Hz directly out of the box. It features EDID-assisted HDMI emulation, which ensures visual workspaces and screen resolutions are remembered every time it connects to a new system: it™s a powerful, simple, and invaluable tool!

The UHDN-4P-Duo is easy to control in a variety of methods, including:

  • Front Panel Buttons: switch between devices you wish to control and emulate with simple SELECT buttons on the UHDN-4P-Duo™s front panel.
  • USB Keyboard Hot Keys: control switching functions of the UHDN-4P-Duo using programmable Hot Keys on a connected USB keyboard.
  • RS-232 Commands: control switching functions of the UHDN-4P-Duo using RS-232 serial commands.

The 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.
