Dual-Computer Triple-Monitor KVM

This CKLau HDMI KVM switch lets two computers share one keyboard, one mouse, three monitors and a single USB 2.0 peripheral. Audio and microphone ports pass through to the active system. All required input cables are included in the box.

Upgrade from two-monitor or single-PC setups

It replaces a basic two-port, two-display switch when a third monitor is needed for productivity or streaming. The jump is worth it when both computers must drive three screens at up to 4096x2160@60Hz without installing drivers on Windows, Linux or macOS.

4K 60 Hz headroom across three outputs

The switch handles 3840x2160@60Hz, 3440x1440@60Hz and 2560x1440@60Hz on every connected display simultaneously. It runs out of bandwidth for 3840x1080@240Hz on all three ports at once, so ultra-wide high-refresh configurations must drop to a lower refresh rate.
