Dual-monitor KVM matrix for two computers

This HDMI 2.0 KVM matrix lets you share two monitors, one keyboard, one mouse and two USB 3.0 peripherals between two computers or game consoles. It supports mirror, extended and criss-cross display modes with adaptive EDID for Windows, macOS and Linux. The aluminium-alloy enclosure measures 176 by 51 by 21 millimetres.

Thermals, noise and power draw

The unit is a passive switch with no fans, so it adds no audible noise to the desk. Power is drawn only from the connected hosts through the HDMI and USB links; no external power adapter is required. The aluminium shell acts as a heat spreader, keeping surface temperature low during continuous 4K 60 Hz operation.

4K 60 Hz HDMI 2.0 bandwidth limit

Each HDMI 2.0 port handles up to 3840 by 2160 at 60 Hz with RGB 4:4:4 colour, plus 1080p at 120 Hz or 144 Hz. If your workflow needs 4K at 120 Hz or higher refresh rates, this matrix cannot deliver them.

Questions about this item

How do I connect two computers and two monitors to this 2×2 HDMI 2.0 KVM matrix, and which cable do people forget?

Plug each computer into one of the four HDMI 2.0 inputs and one of the two USB-C or four USB 3.0 inputs; connect the two monitors to the two HDMI 2.0 outputs. The step most people miss is attaching the USB-C or USB 3.0 cable so the keyboard, mouse and USB 3.0 hub actually switch with the video.

What part of this aluminium-alloy KVM matrix will need attention after heavy daily use?

The mechanical push-button on top and the HDMI 2.0 ports see the most physical cycles; keep the ports dust-free and reseat cables if you notice 4K 60 Hz or 1080 144 Hz signal drops. The USB 3.0 hub ports can also wear from frequent device swaps.

At what resolution and refresh ceiling does this matrix stop passing a clean signal during long sessions?

The hard limit is 3840×2160 at 60 Hz with RGB 4:4:4 over HDMI 2.0b and HDCP 2.3. Pushing 1080p at 144 Hz or 120 Hz works, but sustained 4K 60 Hz is the first boundary where bandwidth or handshake issues appear.
