The UHDN-4P-Quad is a 4-port, quad-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-Quad 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-Quad is the first quad-head KVM switch on the market to offer full Ultra-HD 4K emulation at 60Hz directly out of the box.
