Quad-monitor KVM for four computers

This CKLau HDMI switch lets four PCs or laptops share one keyboard, one mouse, four monitors and a single USB 2.0 peripheral. Audio and microphone ports are included on the output side. Each source must provide four video outputs to drive the four displays. The unit ships with all required input cables and a DC 5 V 2 A power adapter for stable operation.

Passive desktop unit with external power

The switch draws power from the supplied adapter and has no internal fans, so it adds no audible noise to a workstation. HDMI 2.0 and HDCP 2.2 signalling handle 4K 60 Hz traffic without active cooling. Power consumption is limited to the adapter rating, keeping heat output negligible in normal office or studio environments.

Hot-key and front-panel switching included

Users can change the active computer by pressing a front-panel button or by typing a hot-key sequence such as NumLock + NumLock + port number + Enter. The hot-key combination is configurable to avoid conflicts with Apple keyboards. No driver installation is required on Windows, Linux or macOS, and the built-in EDID management keeps display settings consistent across switches.

Questions about this item

How do I connect the four computers and four monitors to the CKLau 4K KVM switch, and what common step causes no signal?

Connect each computer to one of the four HDMI input ports using the supplied cables, then attach the four monitors to the four HDMI outputs; the step often missed is that every computer must provide four separate video outputs for the quad-monitor layout to work.

Which parts of the CKLau 4K KVM switch are most likely to need replacement after extended use?

The DC 5 V 2 A power adapter and the HDMI cables are the components most likely to require replacement over time, while the switch itself is solid-state and driver-free.

What resolution or refresh-rate limit appears first when running the CKLau 4K KVM switch continuously at maximum load?

The hard ceiling is 4096 × 2160 at 60 Hz per port; sustained operation cannot exceed this resolution or refresh rate on any connected monitor.
