WRIARICH 2x2 HDMI KVM Switch 4K Dual Monitor 3.5mm Audio 4 USB 3.0

2×2 HDMI KVM Matrix for Dual 4K Displays

The WRIARICH 2×2 HDMI KVM switch lets one USB keyboard, one USB mouse and two HDMI monitors control two computers, laptops or game consoles. It supports 3840×2160 resolution at 60 Hz with RGB 4:4:4 colour, plus 1080p at 144 Hz, and passes 3D, HDR and HDCP 2.3 signals. A built-in 3.5 mm audio jack and two USB 3.0 hub ports share peripherals such as printers or external drives at up to 5 Gb/s. No external power adapter is required.

Switching Methods and Matrix Flexibility

Users can change the active source with front-panel push buttons, an infrared remote control or keyboard hotkeys (Ctrl+Shift+1/2 for each PC, Ctrl+Shift+K to toggle hotkey mode). The unit operates in two modes: extended or mirror display switching for simultaneous output changes, and crisscross matrix switching that lets each monitor independently select either computer input. This replaces a basic single-monitor KVM when independent dual-screen workflows are needed.

Ideal for Dual-Screen Multitasking.

The switch suits professionals, streamers or home-office users who run two computers side by side across two monitors and want instant source changes with audio and USB peripheral sharing. It is not designed for buyers who only need a single-display KVM, for systems that cannot drive two external screens, or for installations requiring more than two computer ports or monitor outputs.
