Two-Port KVM for Dual-PC Desks

This LUOM OZK2 switch lets one keyboard, mouse and monitor control two computers. Four USB 3.0 ports share printers, drives or other peripherals between both systems. Plug-and-play operation requires no drivers on Windows, macOS or Linux. A front-panel button toggles the active PC instantly.

Passive Cooling and Bus Power

The unit has no fans, so it adds no audible noise to a quiet workspace. It draws power from the connected computers through the included USB power cable, keeping the signal stable even when a PC enters sleep mode. Typical consumption stays well within standard USB current limits.

4K 60 Hz HDMI 2.0 Bandwidth

Video passes through at 3840 x 2160 pixels at 60 Hz with 18 Gbps bandwidth, HDCP 2.2 and 4:4:4 chroma. Lower resolutions such as 1080p or 2K at 120 Hz are also supported. Buyers needing 4K at 120 Hz or 8K output should choose a different switch.

Questions about this item

How do I connect both computers to the LUOM OZK2 so the 4K@60Hz signal works?

Plug an HDMI cable and a USB data cable from each PC into the two PC ports, connect one monitor to the single HDMI out, then attach the USB power cable to a 5 V source; the switch draws power through HDMI to wake sleeping systems.

What upkeep will the four USB 3.0 sharing ports need over time?

No scheduled maintenance is required; if a peripheral stops enumerating, reseat its cable or move it to another of the four ports — the hub controller handles 5 Gbps traffic without firmware updates.

At what point does the 18 Gbps bandwidth limit appear during heavy use?

The 18 Gbps ceiling is reached when driving 3840 x 2160 at 60 Hz with 4:4:4 chroma; higher refresh rates such as 2K@120Hz drop to 4:2:0 or lower colour sampling to stay within the link budget.
