Two-computer KVM switch

This ESTONE OZK2 switch lets you control two computers from one HDMI monitor and four USB 3.0 peripherals. A single button on the top panel swaps the active system instantly. The unit supports Windows, macOS and Linux without any driver installation. It is built for users who want a simple hardware solution to reduce cable clutter.

Passive cooling and desktop footprint

An aluminium alloy shell dissipates heat without a fan, so the switch runs silently on a desk. The enclosure measures 111.8 x 63.2 x 24.5 mm and weighs 9.52 ounces. Power is drawn from the connected computers through the included USB power cable, eliminating the need for an external adapter. LED indicators show which port is active.

Steady 4K 60 Hz signal under continuous use

The HDMI 2.0 interface maintains 3840 x 2160 resolution at 60 Hz with HDCP 2.2 compliance during extended sessions. Manual switching avoids the brief signal loss that automatic scanning can introduce. The metal housing shields against electromagnetic interference to keep video and USB data stable over long work periods.

Questions about this item

How do I connect both computers to the ESTONE OZK2 so the 4K 60Hz signal and four USB 3.0 ports work correctly?

Plug one HDMI 2.0 cable and one USB 3.0 data cable from each computer into the two input groups on the switch, then connect your monitor to the single HDMI output and up to four peripherals to the four USB 3.0 output ports; the included USB power cable can be used if the computers cannot supply enough bus power.

What ongoing upkeep does the ESTONE OZK2 need to keep the HDMI 2.0 and USB 3.0 links reliable?

No scheduled maintenance is required; keep the aluminium-alloy shell vents clear of dust, verify that all HDMI and USB cables remain firmly seated, and replace any cable that shows physical damage or intermittent connectivity.

At what point does the ESTONE OZK2 hit its video bandwidth ceiling during a long session?

The switch is rated for HDMI 2.0 with HDCP 2.2, so the hard limit is a 3840 x 2160 60 Hz signal; sustained operation at that resolution will not exceed the specified bandwidth.
