Dual Monitor KVM for Three PCs

This Vszerda KVM switch lets one keyboard, one mouse and two monitors control three computers or laptops. It supports extend and duplicate display modes switched with the Windows+P shortcut. An integrated EDID emulator preserves window layouts and applies the optimal resolution automatically when switching between systems.

4K60 and 2K120 Limits

Video bandwidth reaches 4K at 60 Hz and 2K at 120 Hz, with mixed-resolution input such as 4K30, 1440p60, 3D or 1080p60 on different ports. Four USB 3.0 ports share peripherals at up to 5 Gbps, while USB 2.0 would be limited to 480 Mbps. The unit includes a 12 V power adapter and 1.5 m cables for every connection.

Upgrade from Single-Monitor KVM

Replaces a single-display switch when a second monitor is needed for productivity or streaming workflows. The jump is worthwhile when three PCs must share dual screens and four USB devices without re-plugging cables. Buyers who only need one monitor or fewer than three computers will not use the extra ports.

Questions about this item

Should I pick the 3-computer model or a smaller KVM if I only have two PCs?

This unit is built for three computers sharing two monitors; if you only need two PCs you will have an unused port but the switch still works normally.

What does 4K@60Hz actually deliver when I connect my monitors through this switch?

You can run both displays at up to 4K resolution at 60 Hz, or 2K at 120 Hz, and the EDID emulator keeps each PC’s window layout intact when you switch.

How fast are the USB 3.0 ports in practice for file transfers?

The four USB 3.0 ports support up to 5 Gbps throughput, compared with 480 Mbps on USB 2.0, so external drives and peripherals run at full SuperSpeed.
