One-to-four HDMI splitter

The Jansicotek OZF4 takes a single HDMI source and duplicates the signal to four displays at the same time. It supports video resolutions up to 3840 x 2160 at 30 Hz along with 1080p and lower formats. Audio formats including DTS-HD, Dolby TrueHD, DTS, Dolby AC3 and DSD pass through the HDMI outputs. The unit ships with a 5 V DC power supply for stable operation.

Passive cooling and low power draw

The aluminium enclosure dissipates heat without a fan so the splitter runs silently in normal use. Power consumption stays minimal thanks to the external 5 V adapter and the HDMI 1.4b compliant circuitry. Signal integrity is maintained for input cable runs up to 5 m at 1080p and output runs up to 10 m at the same resolution. No active cooling or additional power budgeting is required.

Replaces single-output connections

This splitter replaces the need to swap cables or use multiple source devices when the same image must appear on four screens. It is suited for retail displays, classroom duplication or multi-room viewing from one player or console. The jump is worth it when simultaneous identical output is required across four HDMI displays. It does not extend desktop space or support independent content on each screen.

Questions about this item

How do I install the Jansicotek OZF4 1x4 HDMI splitter and which step do people get wrong?

Connect the included 5 V DC power supply first, then attach one source to the single HDMI input and up to four displays to the four HDMI outputs; the step most often missed is powering the unit before plugging in the video cables.

What maintenance or replacement will the Jansicotek OZF4 HDMI splitter need later?

The splitter itself has no moving parts or user-serviceable items; only the external 5 V DC power adapter may need replacement if it fails after extended use.

What limit appears first when the Jansicotek OZF4 runs continuously at 4K 30 Hz?

The HDMI 1.4 bandwidth ceiling of 3.4 Gbps and 340 MHz TMDS clock caps sustained 4K output at 30 Hz, so higher refresh rates or deeper colour depths cannot be maintained.
