Four-computer KVM switch

The WRIARICH unit lets four computers or laptops share a single monitor and four USB 3.0 peripherals. One keyboard and mouse control every connected system. Switching is handled by front-panel push buttons or the supplied infrared remote. LED indicators show which computer is active.

Upgrade from two-port or manual switching

Replaces a basic two-port KVM or the hassle of swapping cables by hand. The jump is worth it when you run four workstations — such as a desktop, a laptop, a mini PC and a server — and need instant access to all of them from one desk. The included 12 V 1 A power adapter keeps high-draw USB devices recognised reliably.

HDMI 2.1 bandwidth limits

Video tops out at 8K 60 Hz or 4K 120 Hz, with backward compatibility for lower resolutions. USB 3.0 ports deliver up to 5 Gbps and fall back to USB 2.0 and 1.1. The switch requires the external power supply for stable operation with power-hungry peripherals.

Questions about this item

What are the physical dimensions and weight of this 4-port KVM switch?

The unit measures 9.3 x 3.3 x 0.8 inches and weighs 1.81 pounds, fitting on a desk without a mounting bracket.

How do I connect the four computers and the single monitor, and which step is commonly missed?

Plug each computer into one of the four HDMI 2.1 inputs using the supplied USB 3.0 A-to-A cables, connect the monitor to the single HDMI 2.1 output, then attach the 12 V 1 A power adapter — skipping the external power causes unstable USB device recognition.

What ongoing maintenance or replacement items should I expect for this switch?

The infrared remote requires a battery that is not included; insert a fresh cell before first use and swap it when range decreases. The 12 V 1 A power adapter and the four USB 3.0 cables are the only other parts that may need replacement if damaged.
