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.

Questions about this item
What graphics-card ports must my computer already have to drive four monitors through the KC-404DH?
Each computer needs three native DisplayPort 1.4 outputs and one native HDMI 2.1 output; adapters or docking stations will not work.
Will the KC-404DH pass 4K 120 Hz signals from an older GPU that only has HDMI 2.0 and DisplayPort 1.2?
The switch is rated for 4K@120Hz over HDMI 2.1 and DP 1.4, so an older GPU limited to HDMI 2.0 or DP 1.2 cannot deliver that refresh rate.
How can I confirm the KC-404DH is switching correctly after I connect everything?
Press the panel button or wired remote; the front-panel LEDs will light for the active port and all four monitors should instantly show the selected computer's desktop.
