4-Port Dual-Monitor KVM for Four PCs

This KVM switch lets you control four computers or laptops with one keyboard, one mouse and up to two HDMI monitors. It is built for users who need to keep multiple systems active on a single desk without swapping cables. The unit requires each connected PC to support dual-display output for the two-monitor mode to function.

EDID Emulation Keeps Layouts Stable Under Switching

Built-in EDID emulators on every input port store each monitor’s resolution and refresh rate so Windows stay in place when you change sources. The switch conforms to HDMI 2.0 and handles 4K at 60 Hz with YUV 4:4:4, HDCP 1.4 and HDR 2.2, provided both the graphics card and the display support that mode. Separate audio and microphone jacks remain available regardless of which PC is selected.

Replaces Separate Cables

The device removes the need for individual HDMI and USB cables running to each workstation and eliminates the hassle of changing monitor inputs by hand. Two switching methods — front-panel button and wired remote — give quick access without software installation. It is not suited for setups that only have single-display outputs on the source PCs or that require USB 3.0 peripheral bandwidth.

Questions about this item

Does the BUCIER 4 Port HDMI Dual Monitor KVM Switch run hot or draw much power when left on all day?

The unit operates from a 5 volt supply and weighs 0.898 kg, so it produces minimal heat and low power draw during continuous use.

What cables and computer ports must I already have to connect four PCs to this KVM switch?

Each of the four computers needs two HDMI outputs and one USB 2.0 port, plus two HDMI cables and one USB cable per PC to reach the switch.

Will my older Windows 7 or Linux machine work alongside newer Windows 11 PCs through this switch?

Yes, the switch lists compatibility with Windows 7, Windows 11, Linux, Ubuntu, Fedora and other systems, so mixed-generation PCs can share the same keyboard, mouse and dual monitors.
