4-Port HDMI KVM Switch for Four Computers

This WRIARICH KVM switch lets a single keyboard, mouse and monitor control up to four computers. It is suited to offices, teaching spaces, meeting rooms, home theatres and test benches where multiple systems must share one console. The unit operates driver-free across Windows, Mac OS, Linux and Chrome OS, so no software installation is required before use.

Connects Four HDMI Sources

Each of the four computer ports accepts an HDMI video feed and a USB link, while the console side provides one HDMI output and four USB ports for keyboard, mouse, printer, scanner, flash drive or camera. A front-panel button and an included remote key module allow instant switching without reaching behind the rack. The package supplies four USB cables and a power cable for immediate setup.

Maintains 4K 60Hz Output During Continuous Switching

The switch supports 4K resolution at 60 Hz, preserving image clarity and colour fidelity during extended sessions. Its internal signal processing keeps video smooth and stable when moving between sources repeatedly, avoiding drop-outs or flicker that can disrupt long presentations, monitoring tasks or gaming periods.
