Triple-monitor KVM for four computers

The WRIARICH KC-403DH is a new KVM switch that lets one keyboard, mouse and three displays control four separate computers. It presents one HDMI and two DisplayPort monitor connections alongside four upstream USB 3.0 links. The unit targets professionals and enthusiasts who need simultaneous multi-screen access to several systems without duplicating peripherals.

Build integration and peripheral sharing

The switch requires a DC 12 V power adapter, included in the package, and a USB 3.0 cable from each computer to carry both data and bus power for the shared ports. Four USB 3.0 Type-A sockets on the front accept keyboards, mice, printers, scanners, cameras or external drives at up to 5 Gbps. Front-panel push buttons and a wired remote give two ways to select the active system, while LEDs show the current port.

Sustained-operation behaviour

Video bandwidth complies with DP 1.4 and HDMI 2.1, supporting 8K at 60 Hz and a range of lower rates including 4K at 240 Hz, 144 Hz and 120 Hz. Extended mode drives three independent images across the monitors; mirror mode duplicates one image on all three. Full resolution depends on every link in the chain — sources, cables and displays — meeting the same standard.

Questions about this item

Does the KC-403DH throttle or drop frames when running three 8K 60 Hz displays continuously?

The switch complies with DP 1.4 and HDMI 2.1 and supports 8K@60Hz continuously; maximum resolution requires that each source, monitor and cable also support 8K@60Hz.

How much fan noise or heat does the unit produce during all-day operation?

The KC-403DH has no fan; it runs passively from the included 12 V DC adapter and stays cool under normal office loads.

Which cables and ports must my four computers already provide to use all three monitors and USB 3.0 sharing?

Each computer needs one HDMI 2.1 output, two DP 1.4 outputs and one USB 3.0 Type-A port; the package supplies four USB 3.0 A-A cables for the upstream links.
