Four-Computer HDMI KVM Switch

This HDMI KVM switch lets four computers share one monitor and a single keyboard and mouse set. It is built for multi-system workstations, home offices or streaming setups that need quick, button-driven switching between sources.

4K@60Hz Video and Three USB 3.0 Ports

The switch supports a maximum resolution of 3840x2160@60Hz and is compatible with 3840x2160@30Hz and 1080p. Adaptive EDID handles display identification. Three USB 3.0 ports allow shared peripherals such as flash drives or cameras, but hotkey switching is not supported.

Bundled Cables for Immediate Setup

The package includes one HDMI cable, four USB 3.0 cables and one power cable so the unit works out of the box. Buyers who need hotkey switching or more than four computer ports will need a different solution.

Questions about this item

Will the 3840x2160@60Hz output work with my older 1080p monitor?

Yes, the switch is compatible with lower resolutions such as 1080p and 3840x2160@30Hz, and adaptive EDID identifies the connected display automatically.

How can I confirm the switch is actively routing video and USB 3.0 data after I connect everything?

Press the button to cycle through the four ports; the active port LED lights up and the shared monitor instantly shows the selected computer's desktop while keyboard, mouse and any USB 3.0 device follow the same port.

Which cables are included and what else do I need to buy to run four computers?

The box contains one HDMI cable, four USB 3.0 cables and a power cable; you must supply three additional HDMI cables to connect the remaining three computers.
