Control up to four computer systems using a single set of peripherals with the Advanced Secure 4-Port Dual-Head KVM Switch from Belkin. You can access these systems utilizing two HDMI-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.
