Dual-computer dual-monitor control

The LUOM OZK3-1 is a 2-port HDMI KVM matrix that lets one keyboard, one mouse and two monitors manage two computers or game consoles. It accepts two HDMI and USB-C inputs from the hosts and delivers two HDMI outputs plus analogue audio. The aluminium-alloy chassis measures 176 by 51 by 21 millimetres and weighs 9.52 ounces.

Sustained 4K60 operation

The switch maintains 3840 by 2160 at 60 Hz RGB 4:4:4 without frame drops during long sessions, and also handles 1080p at 144 Hz or 120 Hz for high-refresh needs. HDMI 2.0b and HDCP 2.3 compliance keeps protected content flowing. Hot-key, front push-button and IR remote switching all operate instantly, and the 3-second auto-scan cycle runs continuously without overheating the pass-through circuitry.

Matrix not splitter

This unit is a true 2-in 2-out matrix: each monitor can show a different computer at the same time, so buyers who need both screens mirrored to a single host cannot use this topology. It also lacks USB 3.0 downstream bandwidth for high-speed storage, so users who must share fast external drives should look elsewhere.

Questions about this item

Does the LUOM OZK3-1 KVM switch run hot or draw much power when it stays on all day?

The unit ships with a USB power cable and an aluminium alloy shell that acts as a heatsink, so it stays cool and draws only the low power needed for HDMI 2.0b and USB 3.0 signalling during continuous operation.

Which cables or ports must I already have on my two computers to connect them to this KVM?

Each computer needs one HDMI 2.0 output and one USB-C or USB 3.0 port; the box includes two USB data cables and the KVM provides four HDMI 2.0 inputs and two USB-C inputs for those connections.

Will my older 1080P monitors at 120 Hz or 144 Hz work correctly through this switch?

Yes — the switch supports 1080P at 120 Hz and 144 Hz as well as 4K at 60 Hz, so legacy high-refresh-rate displays run at their native rates without downscaling.
