2-in-2-out HDMI KVM matrix
The ESTONE OZK3-1 lets two computers share one keyboard, one mouse and two HDMI monitors. It accepts two HDMI and two USB-C inputs from the sources and delivers two HDMI outputs plus stereo audio. The matrix topology allows any source to appear on either display independently.
Sustained 4K 60 Hz operation
HDMI 2.0b and HDCP 2.3 compliance keep the link stable during long work sessions at 3840 x 2160 and 60 Hz. The aluminium-alloy shell dissipates heat without fans, so signal quality does not degrade when the unit runs continuously. Switching between computers takes roughly three seconds in auto-scan mode.
HDMI 2.0 bandwidth ceiling
The 2.0 interface caps video at 4K 60 Hz 4:4:4 or 1080p at 144 Hz; higher refresh rates or deeper colour at 4K are not possible on this standard. USB 3.0 ports add peripheral sharing but do not carry video. Adapters can convert DVI or DisplayPort sources to the HDMI inputs.

Questions about this item
Does the ESTONE OZK3-1 run hot or draw much power when left on 24/7?
The unit has no fan and uses a small 5 V USB power adapter, so heat and power draw stay low even with both PCs running all day.
Which cables do I need to already own so both computers connect to the two HDMI outputs?
Each computer needs one HDMI 2.0 cable and one USB-C to USB-A cable; the box includes two USB data cables and a power cable only.
Will my older 1080P 144 Hz monitor work alongside a newer 4K 60 Hz screen on this switch?
Yes — the matrix handles 1080P at 144 Hz on one port and 3840×2160 at 60 Hz on the other simultaneously.
