ESTONE OZF4C 1x4 HDMI Splitter

The ESTONE OZF4C duplicates a single HDMI source across four displays simultaneously. It transmits video and audio together without signal loss and includes a 5V/1A power adapter for stable operation. The unit supports HDCP 1.4b and 1.4 for protected content playback.

Ideal for multi-room viewing and signage

This splitter suits users who need identical mirrored output on four screens such as monitors, projectors or TVs. It does not support extended desktop modes so buyers who want independent displays should look elsewhere. It also lacks HDCP 2.2 compatibility required by some newer 4K streaming services.

Maximum resolution 3840 x 2160 at 30 Hz

The single specification that decides fit is the 4K output capped at 30 Hz via HDMI 1.4. Sources and cables must match this bandwidth to achieve the stated resolution. Higher refresh rates at 4K are not supported by this device.

Questions about this item

How do I install the OZF4C splitter and what step is often missed?

Connect the source to the single HDMI input, link up to four displays to the HDMI outputs, then plug in the included 5V/1A power adapter — skipping the power adapter is the step that causes no signal.

What maintenance or replacement will the OZF4C need over time?

The unit has no user-serviceable parts; only the external 5V/1A power adapter may need replacement if it fails after extended use.

What limit appears first when running four 4K displays continuously on the OZF4C?

The HDMI 1.4 interface caps 4K resolution at 30 Hz, so sustained 4K@60 Hz is not possible — 30 Hz is the hard ceiling.
