4-Port Dual-Monitor KVM Switch

This Vszerda KVM switch lets one keyboard, one mouse and two monitors control four separate computers. It shares three USB 3.0 peripherals and provides dedicated 3.5 mm audio and microphone ports. The unit is aimed at multi-system workstations, streaming setups or server rooms where desk space and cable count must stay low.

Upgrade from single-monitor or two-port switches

The jump makes sense when a user adds a third or fourth PC and needs simultaneous 4K 60 Hz output on both screens with HDCP 1.4 and HDR 2.2 support. It also replaces separate USB hubs and audio splitters by consolidating 5 Gbps USB 3.0 sharing and a built-in DAC for clean analogue output. Buyers who only run one or two machines will not use the extra ports.

Plug-and-play installation with cabling discipline

No driver is required on Windows, Linux, Mac, Unix, Ubuntu or Raspberry Pi; switching works via front-panel buttons or the wired remote. The main pitfall is cable management: each computer needs one DisplayPort cable, one HDMI cable and one USB-A-to-B 3.0 cable connected to matching labelled inputs, plus the monitor cables on the output side. Missing or mismatched cables on any port will break video, USB or audio for that system.
