Two-Computer KVM with 8K@30Hz and 4K@120Hz Support

This ESTONE OZK1-New switch lets two computers share one HDMI monitor, three USB 3.0 peripherals and a single RJ45 network device. It handles resolutions up to 7680 x 4320 at 30 Hz and 3840 x 2160 at 120 Hz. Switching is done via the front-panel button or the included remote control. No driver installation is required on Windows, macOS or Linux.

Passive Cooling and Low Power Draw

The unit uses a highly integrated digital chipset that runs without a fan, so operation is silent. Power is drawn from the connected computers through the USB links, eliminating the need for an external adapter. Typical consumption stays low during normal desktop work and 4K@120Hz video playback. The 3-second auto-scan interval can be enabled for unattended monitoring.

Compact Metal Chassis with Front-Facing Ports

The enclosure measures 111.8 x 63.2 x 24.5 mm and weighs 9.52 ounces, fitting easily on a crowded desk. Two HDMI inputs, three USB 3.0 inputs and one RJ45 input sit on the rear; the single HDMI output and three USB 3.0 downstream ports face the front for quick access. LED indicators show the active computer at a glance.

Questions about this item

How do I connect the two HDMI cables and the three USB 3.0 cables so the switch works right away?

Plug each computer into one HDMI input and one USB 3.0 input on the switch; connect the single HDMI output to the monitor and the three USB 3.0 ports on the front to keyboard, mouse and other devices, then press the manual button or use the remote to select the active PC.

Will the remote control need a battery change, and are the front USB ports user-replaceable?

The remote uses a standard coin cell that lasts months; the three USB 3.0 ports and the RJ45 port are fixed on the chassis and are not designed to be swapped by the user.

At what resolution and refresh rate does the HDMI 2.0b link hit its bandwidth ceiling during long sessions?

The HDMI 2.0b interface tops out at 8K 30 Hz or 4K 120 Hz, so sustained 8K 30 Hz or 4K 120 Hz output is the first limit you will reach.
