Two-PC HDMI 2.1 KVM Switch
The ESTONE OZK4 is a 2-port HDMI 2.1 KVM switch that lets one keyboard, mouse and monitor control two computers. It supports video up to 7680×4320 at 60 Hz and passes HDCP 2.3. Four USB 3.0 ports and two USB-C inputs provide peripheral sharing for Windows, Mac and Linux systems.
Plug-and-Play With Button or Hotkey
No drivers are required; the unit is recognised immediately on supported operating systems. Switching is done by pressing the front-panel Select button or by using the Ctrl+Shift+1/2 hotkey combination. An auto-scan mode cycles every 3 seconds, and LED indicators show the active port.
Aluminium Shell Handles Continuous 8K 60 Hz
The aluminium alloy enclosure dissipates heat during extended 8K 60 Hz or 4K 120 Hz sessions without throttling. HDCP 2.3 handshake remains stable over long periods, and the integrated chip maintains signal integrity for high-current USB devices such as external drives.

Questions about this item
How can I verify the ESTONE OZK4 is switching correctly after connecting both PCs and the monitor?
Press the front "Select" button or use the Ctrl+Shift+1/2 hotkeys; the LED indicators will light for the active port and the monitor should display the chosen computer at up to 7680×4320 resolution.
Which cables and peripherals are included with the OZK4 and what must I provide separately?
The switch itself is supplied; you must supply two HDMI 2.1 cables for the video inputs, one HDMI 2.1 cable for the monitor output, and your own keyboard, mouse or other USB 3.0 devices for the four downstream ports.
The OZK4 lists 8K 60 Hz, 4K 120 Hz and 1080p 240 Hz — which mode should I choose for my setup?
Match the mode to your monitor and GPU: use 7680×4320 at 60 Hz for 8K displays, 3840×2160 at 120 Hz for high-refresh 4K panels, or 1080p at 240 Hz for competitive gaming monitors.
