Four-computer triple-monitor KVM

This WRIARICH KVM switch lets four desktops or laptops share one keyboard, one mouse and three monitors connected through two HDMI ports and one DisplayPort. It targets users who need simultaneous extended or mirrored desktops across three screens without replugging cables. The unit also provides three USB 3.0 ports and separate audio and microphone jacks for shared peripherals.

Driver-free setup with two switching methods

The switch operates without extra software on Windows, Linux, Mac, Unix, Ubuntu and Raspberry Pi systems. Each computer requires two HDMI cables, one DisplayPort cable and one USB 3.0 cable to enable the triple-screen layout; missing any of these connections will leave a monitor dark. Switching between the four sources is done either by front-panel push buttons or the included wired remote control.

Passive cooling handles continuous multi-stream

Because the device draws power from the included adapter and has no internal fan, it runs silently during long sessions driving three 4K or 8K streams. The aluminium chassis dissipates heat from the HDMI 2.1 and DP 1.4 signal paths, so extended rendering or monitoring workloads do not cause thermal throttling or signal drop-out.

Questions about this item

How do I confirm the KVM switch is passing 8K@60Hz video to all three monitors after setup?

Check each monitor's on-screen display or OS settings to verify 8K@60Hz on the HDMI ports and 4K@144Hz on the DisplayPort port; the LED indicators on the switch show which computer is active.

Which cables and accessories are included, and what must I buy separately for four computers?

The box contains the KVM switch, four USB 3.0 cables, a power adapter, a wired remote button, and a manual; you must supply eight HDMI cables, four DisplayPort cables, and four USB 3.0 cables to connect all four PCs.

Which video-port combination should I choose if my computers have mixed HDMI and DisplayPort outputs?

This model is fixed at two HDMI and one DisplayPort per computer; if a PC lacks a DisplayPort output you will need an active adapter to feed the DisplayPort input on the switch.
