Triple-Monitor KVM for Three PCs

The WRIARICH KC303DH lets you control three computers with one keyboard, one mouse and three displays connected over HDMI and two DisplayPort links. It supports extended and mirrored desktop modes so each monitor can show a different workspace or the same image across all three screens. A wired remote and front-panel buttons give instant switching without reaching behind the desk. The unit ships with all required USB 3.0 cables and a 12 V power adapter for stable operation.

Ideal for multi-system workstations not

Content creators, traders and IT administrators who run three separate towers or laptops will benefit from the unified peripheral set and 5 Gbps USB 3.0 ports for keyboards, mice, printers or storage. Each computer must provide one HDMI and two DisplayPort outputs; machines with only one video port or without multi-display support cannot use this switch. Buyers needing more than three systems or more than three monitors should consider a larger matrix solution instead.

Video path limited to HDMI 2.1 and DP 1.4 bandwidth

The HDMI input accepts 8K at 60 Hz or 4K at 120 Hz while each DisplayPort input handles 8K at 30 Hz or 4K at 120 Hz, so 4K at 144 Hz is only achievable over the HDMI link with certified cables. USB 3.0 peripherals share a 5 Gbps pool across the four downstream ports. The metal enclosure measures 6.3 by 2.56 by 1.77 inches and weighs 15.87 ounces, fitting neatly on a crowded desk.
