4-Port Dual-Monitor KVM

The BUCIER DP402A-B-H lets one keyboard, mouse and two monitors control four computers. It supports extended or mirrored desktop layouts across both screens. Four USB 2.0 ports share peripherals such as printers, scanners or webcams between all connected systems. No external power supply is required for operation.

Compatibility Check

Each computer must provide two DisplayPort outputs to drive both monitors. Verify that your source devices and displays support 3840x2160 at 60 Hz for the full 4K experience. The switch conforms to DP 1.2 with an 18 Gbps transfer rate and uses adaptive EDID for automatic display detection. It works with Windows, Linux, UNIX, Ubuntu, Fedora and macOS without drivers.

Upgrade Path

This unit replaces single-monitor KVMs or basic two-port switches when you need four computers on a dual-screen desk. The jump is worthwhile if you currently swap cables or run multiple keyboard and mouse sets. Push-button and wired-remote switching give instant control without software overhead.

Questions about this item

What cables and accessories are included with the BUCIER DP402A-B-H KVM switch, and which ones do I need to buy separately?

The switch unit is supplied with a wired remote button. You must provide four DisplayPort cables to connect each computer and two DisplayPort cables for the monitors, plus any DP adapters required by your graphics outputs.

How do I decide between using extended mode or mirrored mode on the dual-monitor KVM?

Choose extended mode when each computer can drive two independent 3840x2160@60Hz desktops and you want different content on each screen; choose mirrored mode when you need identical output on both monitors or the source only supports a single DisplayPort signal.

What does the 4K@60Hz rating mean when the switch is connected to real hardware?

When both the source and the display support 3840x2160@60Hz, the DP1.2 link runs at 18Gbps and passes the full resolution; if either end is limited to a lower refresh rate or resolution, the switch automatically adapts via EDID.
