WRIARICH 4-Port 3-Monitor KVM Switch 2 HDMI + 1 DP 8K@60Hz 4K@144Hz USB 3.0 Audio

Four-computer triple-monitor KVM

The WRIARICH switch lets four desktops or laptops share one keyboard, mouse and three displays connected through two HDMI ports and one DisplayPort. It is aimed at users who need extended, mirrored or spliced layouts across all three screens from any of the attached systems. Each source must already support triple-output graphics for the extended modes to function. Buyers who only have single or dual-output machines will not gain extra monitors from this device.

Sustained 8K and high-refresh operation

The DisplayPort output handles up to 8K at 30 Hz and 4K at 144 Hz, while both HDMI outputs reach 8K at 60 Hz and 4K at 60 Hz, all compliant with DP 1.4 and HDMI 2.1 standards. Because the unit draws power from the included adapter rather than the host ports, signal integrity remains stable during long sessions without voltage droop. The three USB 3.0 ports maintain 5 Gbps throughput for attached peripherals even while video is switching. Users who need higher refresh rates than 144 Hz at 4K or 8K beyond 60 Hz will find those modes unsupported.

Rear-facing ports and wired remote

All video, USB and audio connectors sit on the rear panel so cables stay hidden and the desk surface stays clear. A wired push-button remote is included for switching without reaching the main unit, while front-panel LEDs show the active port at a glance. The chassis measures 23.2 by 17.2 by 5.9 cm and weighs 970 grams, making it compact enough to tuck behind a monitor stack. Buyers who prefer front-access cabling or a fully wireless switching method will need a different form factor.
