Four-computer dual-monitor KVM

This LUOM SW243-2HD switch lets four computers share one keyboard, one mouse and two HDMI monitors. It handles 8K at 60 Hz and 4K at 144 Hz with HDCP 2.3 support. Four USB 3.0 ports add shared peripheral access for printers, drives or webcams. The aluminium-alloy chassis provides shielding and passive cooling.

Build integration and cabling

The unit needs a 12 V 1 A external power adapter to run reliably with high-power USB devices. Each computer connects through one HDMI 2.1 cable and one USB 3.0 Type-A cable, all four sets included in the box. Two HDMI 2.1 outputs feed the monitors. Front-panel push buttons and the supplied IR remote give instant switching without software drivers.

Bundled accessories and practical impact

The package supplies four USB 3.0 A-to-A cables so no separate purchases are required. A 12 V power brick, an IR extender cable, a handheld remote (batteries not included) and a user manual complete the kit. Together they enable plug-and-play deployment and let operators change the active PC from across a desk or equipment rack.

Questions about this item

Does the 12V 1A power adapter prevent instability when all four computers and four USB 3.0 peripherals are active for hours?

Yes, the included 12V 1A external power adapter is supplied specifically to maintain stable operation when high-power devices are connected continuously.

How loud does the aluminium-alloy chassis get when the switch runs all day at 8K 60Hz?

The aluminium-alloy shell is passively cooled with no fan, so the unit produces no audible noise during extended 8K 60Hz operation.

Must I already own HDMI 2.1 cables to use the 4-in 2-out switch with my four computers and two monitors?

The package provides four USB 3.0 A-to-A cables, but no HDMI cables; you need four HDMI cables for the computer inputs and two HDMI cables for the monitor outputs.
