WRIARICH 4-port HDMI KVM switch 4K 60 Hz dual monitor 3 USB 3.0 audio

Four-computer dual-monitor KVM

This WRIARICH KVM switch lets one keyboard, mouse and two HDMI monitors control four separate computers. It handles video up to 4K@60 Hz with YUV 4:4:4 colour, HDCP 1.4 and HDR 2.2, and includes built-in EDID emulation on every input. Three USB 3.0 ports share peripherals at up to 5 Gbps, while 3.5 mm jacks carry independent headphone and microphone audio. A wired remote and front-panel buttons give two ways to switch the active PC.

Suits multi-system desks, not single-PC users

The switch is built for operators who run four towers, laptops or a mix of both and need simultaneous dual-monitor output from each. Each source must provide two HDMI outputs, so single-HDMI laptops or devices without dual-head graphics cannot use all features. Buyers who only need to share one monitor, or who want wireless switching, should look at something else.

Bundled cables and remote remove extra purchases

The box supplies four USB 3.0 Type-A to Type-B cables, a 3.5 mm audio splitter cable is not included, a wired remote button, a power adapter and a manual. Having the host cables and remote in the package means the unit works immediately without hunting for compatible leads or a separate DC supply. The adapter also guarantees stable USB 3.0 power when all four ports are loaded.
