Jansicotek OZF2 4K@30Hz HDMI 1x2 video splitter

What this splitter does

The Jansicotek OZF2 is a 1x2 HDMI splitter that takes a single 4K@30Hz source and duplicates it to two displays simultaneously. It passes video and audio together, supporting deep colour up to 36bit and audio formats such as DTS-HD and Dolby TrueHD. The device draws power from the HDMI connection itself, so no external supply is required. It is suited for users who need identical output on two screens, such as a TV and a projector.

Check your source and cables

Verify that your source device can output 4K at 30Hz or 1080p at 60Hz over HDMI 1.4a, as the splitter mirrors the input signal without scaling. Both attached displays must support the same resolution and refresh rate, because the unit does not extend the desktop or handle CEC. Use HDMI cables rated for the bandwidth you need, especially for 4K@30Hz runs. The package includes a USB cable for optional power if the source port cannot supply enough current.

How it fits in a setup

The splitter sits between one HDMI source and two HDMI sinks, mirroring the signal to both. Its slim black enclosure measures 5.59 by 3.15 by 1.26 inches and weighs 3.2 ounces, so it can be tucked behind equipment or mounted discreetly. Because it is powered from the HDMI line, it frees up a mains socket and reduces cable clutter. The box contains the splitter, a USB cable and a user manual.
