Triple-monitor KVM for two computers

The LUOM SW231-3HD lets two desktops or laptops share one keyboard, one mouse and three HDMI monitors. Each computer must already support three simultaneous display outputs for extended or mirrored modes. Four 5 Gbps USB 3.0 ports are also shared between the two systems for peripherals or storage devices.

Silent solid-state operation

The unit has no moving parts, so it adds no audible noise to the workspace. It draws power from the included 12 V adapter and consumes only a small standby current when idle. All HDMI and USB cables connect to rear-facing ports, keeping the desk surface clear of cable clutter.

Stable 8K 60 Hz switching under load

Video bandwidth handles 8K at 60 Hz, 4K at 120 Hz, 3440×1440 at 144 Hz, 1440p at 144 Hz and 1080p at 240 Hz without signal degradation during extended sessions. HDMI 2.1 and HDCP 2.3 compliance maintains protected content paths across both computers. Switching via front button or wired remote is instantaneous and does not reset monitor EDID handshakes.

Questions about this item

How do I connect the two computers to the LUOM SW231-3HD and which step is often missed?

Connect each computer with one HDMI cable and one USB 3.0 cable to the three input ports per system, then attach three monitors to the output ports; the step often missed is plugging in the included 12V power adapter before switching.

What maintenance or replacement will the LUOM SW231-3HD need over time?

The unit has no user-serviceable parts; keep the ventilation slots clear of dust and verify the 12V power adapter and included USB 3.0 cables remain undamaged, replacing only those accessories if they fail.

What limit appears first when running three 8K@60Hz displays continuously on the LUOM SW231-3HD?

Sustained 8K@60Hz across all three monitors demands the full HDMI 2.1 bandwidth and HDCP 2.3 handshake; the first limit is typically thermal, so ensure airflow around the 5.43 x 5.35 x 1.46 inch chassis to avoid throttling.
