WRIARICH KC-404DH HDMI 2.1 + 3 DP 1.4 KVM Switch 4-Port 8K@30Hz 4K@120Hz Wired Remote

Quad 8K@30Hz KVM Switch

The WRIARICH KC-404DH is a four-port KVM switch that lets one keyboard, mouse and quad-monitor array control up to four desktop computers. It accepts HDMI 2.1 and three DisplayPort 1.4 inputs per system and drives all four displays at up to 8K@30Hz or 4K@120Hz. A wired remote and front-panel buttons provide instant switching.

Desktop builders with multi-GPU rigs

This unit suits users whose graphics cards expose three native DisplayPort outputs and one HDMI 2.1 output. It cannot support laptops, docking stations or any host lacking that exact port mix. Buyers who need matrix routing — sending any input to any output independently — should look elsewhere, as each output is locked to its corresponding input layer.

Four 5Gbps USB 3.0 ports and TF card slot

The integrated hub handles keyboards, mice, printers and USB drives at 5Gbps throughput, ten times the speed of USB 2.0. A TF card reader adds removable-media convenience. The switch ships with a 12V DC adapter, four USB 3.0 cables and the wired remote, so the only headroom limit is the host GPU’s native quad-display capability.
