Splitter for one source to four displays

The Jansicotek OZF4 takes a single HDMI signal and mirrors it to four identical outputs simultaneously. It supports resolutions up to 3840 x 2160 at 30Hz with a maximum data rate of 3.4Gbps and TMDS clock up to 340MHz. The unit handles 8/10/12 bit deep colour and passes audio formats including DTS-HD and Dolby-trueHD.

Powered unit with cable distance limits

A 5V DC power adapter is included and required for operation. The splitter works with standard AWG26 HDMI cables up to 15 metres for both input and output at lower resolutions. At 4K resolution the supported cable length drops to 8 metres for input and output. It does not extend desktop space; every connected screen shows the same image.

Replaces single-display connections

This splitter replaces a direct one-to-one HDMI link when the same content must appear on four screens at once. The jump is worth it for installers needing simultaneous duplication across multiple rooms or displays without adding a second source device. It will not suit users who need independent images on each monitor or who require HDCP bypass capability.

Questions about this item

How far can I run the HDMI cables at 4K resolution before the 3.4Gbps bandwidth limit causes signal loss?

The splitter supports 4K at 30Hz with input and output cables up to 8 metres each when using AWG26 standard cable.

Does the 5V DC power adapter run warm or make noise when the splitter drives four 4K displays continuously?

The unit is passively cooled with no fan, so it operates silently; the external 5V adapter handles power delivery and may become warm during extended use.

Which HDMI cables do I need to supply myself to connect one source and four displays to this splitter?

You must provide five HDMI cables — one for the source input and four for the display outputs — all meeting AWG26 or better for the supported distances.
