4-Port Dual-Monitor KVM Switch

The WRIARICH switch lets you operate four computers from a single keyboard, mouse and two HDMI monitors. It is aimed at users who need to keep multiple workstations or laptops active on one desk without duplicating peripherals.

USB 3.0 Hub with EDID Emulation and Audio

Each of the four input ports includes an EDID emulator so connected PCs retain correct display data when switched away. Three USB 3.0 ports and a 3.5 mm audio jack with a built-in DAC handle keyboard, mouse, storage devices and microphone without extra adapters.

HDMI 2.0 Bandwidth Limits Resolution to 4K 60Hz

The HDMI 2.0 interface caps video at 3840 x 2160 at 60 Hz with YUV 4:4:4 colour sampling. Higher refresh rates or resolutions beyond 4K are not supported, and dual-monitor extended or mirrored modes depend on each computer's graphics capability.

Questions about this item

What HDMI standard does the WRIARICH 4-port dual-monitor KVM use, and what resolution and refresh rate does it cap at?

It conforms to HDMI 2.0 and supports a maximum of 3840 x 2160 at 60 Hz with YUV 4:4:4, HDCP 1.4 and HDR 2.2.

What cables and space are needed to fit the switch on a desk?

Each of the four computers requires two HDMI cables and one USB 3.0 Type-A-to-B cable; the unit measures 0.79 x 0.39 x 1.18 inches and all ports face the rear to keep the desktop clear.

How is the KVM installed, and which step is most often missed?

Connect the 5 V adapter first, then attach both HDMI outputs to the monitors, then plug each computer’s two HDMI and one USB cables into the corresponding input ports; the step most often missed is powering the unit before connecting any video or USB cables.
