One input to four displays

The LUOM OZF3-1 splits a single HDMI source across four screens simultaneously. It mirrors the same signal to every output, making it suitable for digital signage, multi-room viewing or presentations where identical content is required on each display.

Sustained 4K 60Hz distribution

The splitter maintains an 18.2Gbps bandwidth across all four ports, supporting 3840 x 2160 at 60Hz with 8, 10 or 12-bit deep colour and HDR 10. HDCP 2.2 compliance ensures protected content plays without handshake drops during extended sessions. Sixteen EDID modes let the source negotiate a stable resolution for each connected sink.

Compact metal enclosure with front switches

The black chassis measures 5.59 x 3.15 x 1.26 inches and weighs 3.2 ounces, fitting easily behind a display or in a rack. A USB power adapter is included for reliable operation. Front-panel EDID and scaler switches allow per-output downscaling from 4K to 1080P without re-cabling. Input cables up to 8 metres and output cables up to 15 metres are supported at 4K.

Questions about this item

Does the LUOM OZF3-1 splitter generate noticeable heat or fan noise when powering four 4K 60 Hz displays all day?

The unit is passively cooled with no fan, so it runs silently. Typical warmth is mild; ensure the vents on the black enclosure have a few centimetres of clearance for natural airflow.

Which cables and power source must I already have to use the 1×4 HDMI 2.0b splitter out of the box?

You need one HDMI source cable to the input, up to four HDMI cables to the displays, and a USB power adapter — the package includes a USB power adapter, so only the HDMI cables are your responsibility.

Will the OZF3-1 work with my older 1080p monitors alongside a new 4K screen without manual switching?

Yes. Each of the four outputs can downscale 4K to 1080p independently using the front-panel EDID or scaler switch, so mixed-resolution displays show the correct image automatically.
