Four-Port HDMI KVM Switch

The WRIARICH KVM401A lets four computers share one HDMI monitor, a keyboard, a mouse and up to four USB 3.0 peripherals. It supports video up to 4K at 60 Hz and 2K at 120 Hz, plus 4K at 30 Hz, 3D and 1080p or lower resolutions. A wired remote and front push buttons both change the active system. EDID simulation keeps display settings stable when switching.

Installation And Common Issues

Connect each computer with the supplied HDMI 2.0 cable and USB 3.0 A-to-A cables, each 1.5 m long, then attach the DC power adapter. The unit measures 5.91 x 4.72 x 1.18 inches and weighs 400 g, so it fits on a desk without crowding. USB 3.0 ports run at up to 5 Gbps and are backward compatible. Some wireless keyboard or mouse dongles may need a direct port on the PC if the KVM does not pass their specific protocol.

Ideal For Multi-System Desks

This switch suits users who operate four PCs or laptops from a single screen and want USB 3.0 peripheral sharing with high-refresh 2K or 4K 60 Hz video. It is not for setups that require more than four computer ports, DisplayPort or USB-C video inputs, or switching without an external power supply. Buyers needing 4K at 120 Hz or more than four USB devices should look elsewhere.

Questions about this item

How do I confirm the KVM401A is passing a 4K@60Hz signal to my monitor after I connect everything?

Press the wired remote or front button to select a port, watch the corresponding LED light up, then check your monitor's on-screen display to verify it reports the expected resolution and refresh rate.

Which cables and accessories are included with the KVM401A and what must I supply myself?

The box contains the switch, four 1.5 m USB 3.0 A-to-A cables, one 1.5 m HDMI 2.0 cable, a wired remote, a power cable and a user manual; you only need to provide an HDMI cable for each of the other three computers.

The KVM401A is a single 4-port model — how do I know it fits my setup?

It supports 4K@60Hz and 2K@120Hz video, four USB 3.0 peripheral ports up to 5 Gbps, EDID simulation, push-button and wired-remote switching, and measures 5.91 x 4.72 x 1.18 inches at 400 g.
