Control up to four computer systems using a single set of peripherals with the Advanced Secure 4-Port Quad-Head KVM Switch from Belkin. You can access these systems utilizing three HDMI-enabled and one DVI-I enabled monitors as well as a keyboard and mouse via USB or PS/2 connection. This switch is compatible with host systems that feature DisplayPorts and USB ports. For audio, Belkin has outfitted this switch with 3.5mm ports. To prevent tampering, electrical sensors are on board. Moreover, the port paths are isolated to stop data leaks between systems.
