4-Port HDMI 2.0 KVM Switch

The WRIARICH KVM401A lets four computers share one HDMI monitor and up to four USB 3.0 peripherals. It supports video resolutions up to 4K at 60 Hz and 2560 x 1440 at 120 Hz. A wired remote and front-panel buttons provide instant switching between connected systems. EDID emulation keeps window positions stable during changes.

Multi-system desks needing USB sharing

Ideal for users who operate several PCs but want a single keyboard, mouse, printer and storage drive setup. The switch handles both wired and wireless input devices without extra drivers. Buyers who need to drive two or more monitors simultaneously should consider a different solution. Those requiring switching speeds beyond the provided remote or buttons will not find them here.

4K@60 Hz and 2K@120 Hz video support

The HDMI 2.0 interface caps output at 4K 60 Hz or 1440p 120 Hz, with backward compatibility down to 4K 30 Hz. All four upstream ports use USB 3.0 for 5 Gbps peripheral bandwidth. A 12 V DC power adapter is included for stable operation. Confirm your cables and source devices match these specifications before purchase.

Questions about this item

What cable standard and maximum length does the 7.03-inch wide KVM401A need for 4K 60 Hz video?

Use a short, high-quality HDMI 2.0 cable between each computer and the switch; the supplier notes that long or lower-grade cables can prevent 4K 60 Hz operation.

Which step do users most often miss when installing the KVM401A with four PCs?

Connecting the included 12 V DC power adapter before linking the four HDMI 2.0 and USB 3.0 cables; without external power the switch cannot maintain EDID simulation or USB 3.0 5 Gbps bandwidth.

When should the 1.5-metre wired remote be replaced if its buttons become unreliable?

Replace the remote when switching between the four ports no longer registers on the front-panel LEDs, as the remote is a passive wired device with no user-serviceable parts.
