4-Port Triple-Monitor KVM Switch

The WRIARICH 403B connects four computers to a single keyboard, mouse and three displays. Two HDMI outputs and one DisplayPort output handle extended, mirrored or spliced layouts. Three USB 3.0 ports share peripherals such as printers or flash drives. Separate audio and microphone jacks route sound without re-plugging cables.

Replaces Four Separate Monitor Cables

A single unit eliminates the need to swap HDMI or DisplayPort leads when moving between workstations. The upgrade is worthwhile when daily tasks involve switching a full triple-screen setup across four PCs or laptops. Front-panel buttons and a wired remote both change the active system instantly. LED indicators show which computer is currently selected.

Sustained Multi-System Operation

The metal chassis dissipates heat during continuous 8K60 or 4K144 video throughput. USB 3.0 ports maintain 5 Gbps bandwidth for attached storage while the switch remains powered by the included DC adapter. Firmware-level EDID management keeps each display recognised after every hot-key change. No driver installation is required on Windows, Linux, Mac or other supported operating systems.

Questions about this item

What cables and space are required to fit the 18.5cm × 7cm × 4cm unit and connect four computers to three monitors?

The switch measures 18.5cm × 7cm × 4cm and needs four HDMI cables, one DisplayPort cable, four USB 3.0 cables (included) and three monitor cables (two HDMI, one DisplayPort) routed to the rear ports.

How do I install the KVM and which step is most often missed?

Connect the DC power adapter first, then attach all HDMI, DisplayPort and USB 3.0 cables to the rear ports, plug the wired remote into its jack, and finally power on the computers; skipping the power adapter before signal cables is the common error.

What maintenance or replacement will the 300g switch need over time?

The unit has no user-serviceable parts; only the external DC power adapter or the USB 3.0 / video cables may need replacement if they become damaged or if a higher-specification cable is required for 8K@60Hz or 4K@144Hz operation.
