Triple-Monitor 8K 60Hz KVM

The LUOM SW231-3HD is a new HDMI 2.1 KVM switch that lets two computers share three monitors and four USB 3.0 peripherals. It supports extended or mirrored desktops at up to 8K 60Hz and 4K 120Hz with HDCP 2.3 compliance. Switching is handled by front-panel buttons or the included wired remote. The unit ships with two USB 3.0 cables, a power adapter and a manual.

Ideal for dual-PC workstations

This switch suits professionals who run two laptops or desktops and need a single keyboard, mouse and triple-monitor setup without cable clutter. It works across Windows, Linux and macOS with plug-and-play operation. Buyers who need to connect more than two computers or who require DisplayPort inputs should look at other solutions.

Deciding specification: three HDMI outputs

The defining limit is the three HDMI monitor ports paired with two computer ports. If your workflow demands three screens driven from two hosts at 8K 60Hz or 4K 120Hz, this switch matches that requirement exactly.

Questions about this item

Does the LUOM SW231-3HD run hot or make noise when switching between two computers all day?

The unit has no fan and relies on passive cooling, so it stays silent and only warm to the touch during continuous use.

What cables must I already own to connect two computers and three monitors to this KVM?

You need three HDMI cables for the monitors and two combined HDMI-plus-USB-3.0 cables for the computers; the box supplies only the two USB-3.0 links.

Will my older 4K 60 Hz monitors work alongside a new 8K 60 Hz screen on the SW231-3HD?

Yes, each of the three HDMI 2.1 ports negotiates its own EDID, so mixed resolutions such as 4K 60 Hz and 8K 60 Hz run simultaneously without downscaling the higher display.
