Two-computer KVM switch

The ESTONE OZK2 lets you control two computers from a single 4K monitor and four USB 3.0 peripherals. A push-button on the top panel swaps the active system instantly without unplugging cables or installing drivers. It supports Windows, macOS, Linux and Unix platforms.

Aluminium chassis with HDMI 2.0 and USB 3.0

Each computer connects through one HDMI and one USB 3.0 cable to the switch inputs. The single HDMI output drives a monitor at up to 3840 x 2160 at 60 Hz with HDCP 2.2 compliance. Four downstream USB 3.0 ports share keyboards, mice, printers or storage between both machines.

Stable 4K60 output under continuous use

The metal shell provides electromagnetic shielding and passive heat dissipation so signal integrity holds during long sessions. An auto-scan mode cycles every three seconds if manual switching is not used. A separate USB power cable is included for reliable operation when peripheral draw is high.

Questions about this item

Does the HDMI 2.0 and HDCP 2.2 spec limit 4K output to 60 Hz on this KVM?

Yes, the switch supports 3840 x 2160 at 60 Hz and is limited to that refresh rate by the HDMI 2.0 interface.

How hot does the aluminum shell get and does it need a fan when running 24/7?

The aluminum alloy housing provides passive heat dissipation; no fan is fitted and the unit is designed for long-term stable operation without active cooling.

Which cables must I already have to connect two computers and one monitor?

You need two HDMI cables and two USB 3.0 data cables (one set per computer); the box includes those cables plus a USB power cable.
