Two-computer HDMI KVM switch

The ESTONE OZK1 lets you operate two computers from a single keyboard, mouse and 4K monitor. It accepts two HDMI and USB upstream connections and provides three USB 2.0 ports for shared peripherals. No external power supply is needed because the unit draws power from the HDMI cables. A front-panel button switches the active computer instantly.

4K 60 Hz video with 18 Gbps bandwidth

The switch passes 3840 x 2160 resolution at 60 Hz and remains compatible with 4K at 30 Hz and 1080p signals. HDCP 2.2 and YUV 4:4:4 chroma sampling are supported for protected content and full colour accuracy. The three USB 2.0 ports handle keyboards, mice and high-current storage devices, but the USB interface remains at 2.0 speeds.

HDMI 2.0b and USB 2.0 interface limits

Video bandwidth tops out at 18 Gbps, so higher refresh rates or 8K resolutions cannot be transmitted. USB peripherals operate at USB 2.0 throughput, limiting transfer speed for external drives. Switching is manual only; the auto-scan function cycles every 3 seconds if enabled. The unit measures 5.43 x 5.35 x 1.46 inches and weighs 9.52 ounces.

Questions about this item

Will this KVM work with a PC that only outputs 1080p while the other runs at 4K@60Hz?

Yes, the switch supports 4K@60Hz and is downward compatible with 1080p, so mixed-resolution sources display correctly on the shared monitor.

How can I confirm the switch is passing a 4K@60Hz signal after I connect everything?

The front-panel LED indicators show which port is active; verify on the monitor's on-screen display that it reports 3840 x 2160 at 60 Hz.

Do I need to buy HDMI cables or a power adapter separately?

The box includes the KVM unit, two USB cables and a user manual; you must supply two HDMI cables, and no external power adapter is required because the switch draws power from the HDMI connections.
