2-Port HDMI 2.1 KVM Switch

The ESTONE OZK4 lets you operate two computers from a single keyboard, mouse and 8K monitor. It presents two HDMI 2.1 inputs and two USB-C ports for host connections, plus four USB 3.0 ports for shared peripherals. One HDMI 2.1 output drives the display at up to 7680×4320 resolution. The aluminium-alloy chassis houses a plug-and-play digital switching engine.

Ideal for dual-PC desks.

Users who need to share one screen, keyboard and mouse between a pair of laptops, desktops or consoles will benefit from instant hotkey or front-panel switching. The switch also passes USB 3.0 data for printers or external drives. Buyers requiring simultaneous output to two or more monitors, or who need more than two host ports, should look at a different class of KVM.

Deciding spec: HDMI 2.1 with 8K 60 Hz support

The single specification that determines suitability is the HDMI 2.1 interface capable of 7680×4320 at 60 Hz, plus 4K at 120 Hz and 1080p at 240 Hz. If your monitor and graphics sources match these modes, the switch will transmit them without compression. If your workflow demands higher refresh rates at 8K or DisplayPort signalling, this unit will not meet that requirement.

Questions about this item

What cables do I need to connect two computers to the OZK4 KVM switch?

Each computer requires an HDMI 2.1 cable for video and either a USB-C or USB 3.0 cable for keyboard, mouse and peripheral data.

Will my existing 4K 120 Hz monitor work with this switch?

Yes, the switch supports 3840×2160 at 120 Hz and will pass that resolution through to the single HDMI 2.1 output.

How can I confirm the switch is passing an 8K 60 Hz signal after setup?

Check the on-screen display or GPU control panel on the active computer; it should report 7680×4320 at 60 Hz with RGB 8:8:8 colour.
