HDN-4Plus is a dedicated multi-platform KVM switch capable of managing four computers through a single HDMI monitor, USB keyboard, USB mouse, and other USB 2.0 devices. This is the first KVM switch on the market that features support for 4K Ultra HD (3840x2160 @30Hz) workstations. The device also features SmartPreview technology, which enables simultaneous picturein-picture monitoring of the other sources connected to switch.
