What this KVM switch does

The ESTONE OZK1 is a 2-port HDMI KVM switch that lets two computers share one 4K monitor, a keyboard and a mouse. It supports 3840 x 2160 resolution at 60 Hz with HDMI 2.0b and HDCP 2.2 compliance. Three USB 2.0 ports on the front provide peripheral connectivity for both systems.

Check your cables and sources before ordering

Each computer needs an HDMI output and a USB-A port for the included cables. The switch draws power from the HDMI links, so both hosts must supply 5 V on the HDMI pins. Verify that your graphics cards can drive 4K at 60 Hz over HDMI 2.0b and that your monitor accepts YUV 4:4:4 chroma at that rate.

Steady operation under continuous use

The unit runs passively without a fan or external adapter, so temperatures stay low during all-day switching. LED indicators show the active port instantly, and the manual button toggles cleanly without signal dropout. Auto-scan cycles every 3 seconds if enabled, but the hardware is built for manual control in long sessions.

Questions about this item

What cables are included and what do I still need to connect two computers?

The box contains the KVM switch, two USB cables and a manual. You must supply two HDMI cables — one from each computer to the switch — and a third HDMI cable from the switch to your monitor.

The product mentions 4K at 60 Hz and 4K at 30 Hz — which should I plan for?

The switch supports full 18 Gbps bandwidth, HDMI 2.0b and HDCP 2.2, so 4K at 60 Hz with YUV 4:4:4 is available when your graphics cards and monitor also support HDMI 2.0. If any link is limited to HDMI 1.4, the signal falls back to 4K at 30 Hz or 1080p.

Will 4K at 60 Hz actually appear on my screen without extra setup?

Yes — the unit is powered through the HDMI cables, requires no driver, and switches with the front button. As long as both computers output 3840×2160 at 60 Hz over HDMI 2.0 and your monitor accepts that signal, the switch passes it through unchanged.
