Dual-system quad 4K workstation control

This DisplayPort KVM switch lets one keyboard, mouse, speaker set and four monitors control two computers at up to 3840 x 2160 60 Hz with HDR10. It targets video editors, CAD operators and content creators who need simultaneous quad-display workflows across a pair of host systems without cable swapping.

Passive thermal envelope 36 W max draw

The steel chassis operates from 0 °C to 40 °C with no fan, drawing up to 36 W from the included 12 V 3 A universal AC adapter. Front-panel LEDs show power, sync and the active host, while auto-scan intervals of 3, 8, 15 or 30 seconds cycle sources without audible noise.

No cables bundled; front USB 3.0 hub adds

The package supplies the switch, a multi-region power adapter, rubber feet and a quick-start guide but no DisplayPort or USB cables. Two USB 3.0 Type-A ports on the front deliver 5 Gbps for storage or docks, while four USB 1.1 HID ports handle keyboard and mouse, and analog plus DisplayPort audio paths carry stereo or 5.1 channel sound.

Questions about this item

How do I connect four DisplayPort monitors to the two host ports without mixing up the video cables?

Each host needs four DisplayPort cables — one per monitor — plugged into the matching numbered ports on the back; the step people miss is keeping each host's four cables grouped so monitor one always maps to host one's port one.

Which parts will need replacement first if I run this switch 24/7 at 40 °C ambient?

The internal 12 V 3 A power supply and the Genesys Logic GL3523 chipset run continuously at 36 W; electrolytic capacitors in the adapter typically age first under sustained heat.

What throughput limit appears first when I push 4K 60 Hz video plus USB 3.0 data through both hosts simultaneously?

The DisplayPort 1.2 links cap each monitor at 3840 x 2160 60 Hz, while the USB 3.0 hub shares 5 Gbps across the two front Type-A ports, so video bandwidth saturates before USB does.
