Jansicotek OZF4C Ultra HD 4K 30 Hz 1x4 HDMI Splitter Resolutions Up to Ultra 4Kx2K@30Hz 1080P

One input to four displays

This Jansicotek OZF4C splitter duplicates a single HDMI source across four screens simultaneously. It transmits video and audio together without signal loss. The unit supports resolutions up to 3840 x 2160 at 30 Hz and is backward compatible with 1080P at 60 Hz and lower formats. A 5V/1A power adapter is included in the box.

Check cables and HDCP version

Verify that your source device and all four displays use standard HDMI connectors. The splitter complies with HDCP 1.4b and 1.4 but does not support HDCP 2.2, so protected 4K content requiring the newer standard will not pass through. Keep input cables under 5 metres for 1080P signals and under 10 metres for lower resolutions. The device cannot extend a desktop; it only mirrors the same image to every output.

Replaces single-output connections

If you currently swap cables or use a basic two-way splitter to share one player among multiple rooms, this four-port model removes that hassle. The upgrade is worthwhile when you need simultaneous mirrored output to four monitors, projectors or TVs from a single console, PC or streaming stick. Buyers who need independent extended desktops or more than four outputs should look elsewhere.
