Triple-monitor KVM for two systems

The LUOM SW231-3HD connects two computers or laptops to three HDMI displays, letting one keyboard and mouse control both sources. It is aimed at multitaskers who need simultaneous visibility across three screens without duplicating input devices. The unit also provides four USB 3.0 ports for shared peripherals such as drives or scanners.

8K 60Hz and 4K 120Hz headroom

Triple-monitor output reaches 8K at 60 Hz and 4K at 120 Hz, with support for both extended and mirrored desktop modes. HDMI 2.1 and HDCP 2.3 compliance ensures compatibility with current high-resolution sources. Bandwidth limits appear when all three outputs run at the highest refresh rates simultaneously.

HDMI 2.1 interface constraints

The switch relies on HDMI 2.1 signalling for its top resolutions, so every cable and source port must meet that specification to achieve 8K 60 Hz or 4K 120 Hz. Older HDMI 2.0 ports will fall back to lower modes. Switching is manual via front buttons or the wired remote; no automatic hot-key or software control is provided.

Questions about this item

Will the 8K 60Hz output work with my existing 4K 120Hz monitors?

Yes, the switch supports 8K at 60Hz and is backward compatible, so your 4K 120Hz monitors will work at their native resolution and refresh rate.

How can I confirm the switch is actively controlling the correct computer?

The unit has LED indicators that show which of the two connected computers is currently selected, and you can switch using the push buttons on top or the wired remote.

Do I need to buy any extra HDMI or USB cables to connect two computers and three monitors?

The box includes the KVM switch, two USB 3.0 cables, a 12V/1A power adapter, a wired button switch, and a user manual. You will need to supply six HDMI cables — three for the monitors and three for the two computers.
