ESTONE OZK1 KVM Switch

The ESTONE OZK1 is a 2-port HDMI 2.0b KVM switch that lets two computers share one monitor and three USB 2.0 peripherals. It handles video up to 3840 x 2160 at 60 Hz with HDCP 2.2 and 18 Gbps bandwidth. Switching is manual via a front button with a 3-second auto-scan option, and the unit draws power from the HDMI cables so no external adapter is needed.

Suited for dual-PC desk setups

This switch suits users who need to control two computers with a single keyboard, mouse and display — typical for office hot-desking, teaching stations or a home desk with a work laptop and a personal PC. It is not for buyers who need more than two computer ports, who require USB 3.x speeds for storage devices, or who want automatic switching triggered by keyboard hotkeys.

Deciding spec: two HDMI inputs, one output

The defining limit is the 2-in-1-out HDMI topology combined with three USB 2.0 ports; if your workflow demands three or more video sources, higher USB bandwidth, or EDID emulation for headless operation, this model will not meet those requirements.

Questions about this item

What bandwidth does the HDMI 2.0b interface provide in practice?

The switch delivers full 18 Gpbs bandwidth, enabling 4K at 60 Hz and 2K at 120 Hz with HDCP 2.2 and YUV 4:4:4 chroma sampling.

What are the exact dimensions and weight for desk mounting?

The unit measures 5.43 x 5.35 x 1.46 inches (111.8 x 63.2 x 24.5 mm) and weighs 9.52 ounces.

How is the KVM powered and what is the common setup mistake?

It draws power from the HDMI cables so no adapter is needed; the step users miss is connecting both computers' HDMI and USB cables before switching.
