Dual-monitor KVM for two computers

This ESTONE OZK3-1 matrix lets a single keyboard, mouse and two HDMI displays control two PCs, laptops or game consoles. Switching is handled by front-panel push buttons, hot-key combinations or the included IR remote. The unit supports HDMI 2.0b with HDCP 2.3 and carries USB 3.0 data plus 7.1-channel audio. Aluminium alloy housing provides shielding and durability.

Replaces separate switchers and cable swapping

If you currently unplug cables or use a single-monitor KVM, this device adds simultaneous dual-screen output with synchronous or criss-cross layouts. The upgrade is worthwhile when you need 4K at 60 Hz on both monitors plus USB 3.0 peripheral sharing without software drivers. It does not suit users who only need single-display switching or who require more than two computer ports.

HDMI 2.0b bandwidth limits resolution and refresh

The interface caps 4K at 60 Hz and 1080p at 144 Hz with RGB 8:8:8 colour; higher refresh rates at 4K or uncompressed 10-bit colour are not possible. Auto-scan dwells three seconds per port, which may be slow for rapid multi-system checks. USB 3.0 ports supply data only, so high-power bus devices may need their own adapters.

Questions about this item

What depth clearance does the 176 x 51 x 21 mm aluminium chassis need on my desk?

The unit is 176 mm deep, 51 mm wide and 21 mm high, so allow at least that footprint plus cable bend radius behind the HDMI and USB-C ports.

Which cable do I plug in first so the hot-key and IR switching work reliably?

Connect both HDMI 2.0 cables and the two USB-C or USB 3.0 data cables to each computer, then attach the USB power cable before turning on the PCs.

The IR remote ships without a battery — which size do I buy?

It takes a single AAA cell; insert it before using the remote for one-button or hot-key switching.
