Four-Computer HDMI KVM Switch

This WRIARICH switch lets four computers share one HDMI monitor and three USB 2.0 peripherals such as a keyboard, mouse and printer. It supports video output up to 3840x2160 at 30Hz. The unit is aimed at office, classroom or home-theatre setups where multiple PCs need to access a single display and input devices.

Replaces Manual Cable Swapping

Instead of unplugging and reconnecting HDMI and USB leads every time you change machines, you switch by pressing the front-panel button or using the wired remote. The jump is worth it when you regularly move between four computers and want instant switching without driver installation or software configuration.

Check Monitor and Port Compatibility

Verify that your monitor accepts 3840x2160 at 30Hz over HDMI and that each computer provides an HDMI output plus a USB 2.0 port for the combined KVM cables. The included cables carry both signals, so no separate HDMI or USB leads are required. Ensure the switching method — button or remote — suits your desk layout.

Questions about this item

What cables come in the box to connect four computers to the KVM switch?

The package includes four combined KVM cables, each carrying one HDMI and one USB 2.0 connection, so every computer links with a single cable.

How do I switch between the four connected PCs and what is the common mistake?

Press the front panel button or use the external controller; the common mistake is forgetting to connect the USB 2.0 plug on each KVM cable, which leaves keyboard and mouse unresponsive.

What resolution and refresh rate does the HDMI output support for the shared monitor?

The HDMI output delivers up to 3840x2160 at 30 Hz, so the shared monitor runs at 4K 30 Hz.
