1x4 HDMI Splitter for 4K Mirroring

The LUOM OZF4 takes a single HDMI source and duplicates it across four displays at up to 3840 x 2160 resolution and 30Hz refresh. It supports 8, 10 and 12 bit deep colour along with audio formats such as DTS-HD and Dolby-trueHD. The unit is aimed at installers and home users who need identical content on multiple screens without extending the desktop.

Plug-and-play installation with powered supply

No drivers are required; connect the source, attach up to four displays and plug in the included 5V DC adapter. The splitter handles TMDS clock rates up to 340MHz and a maximum data rate of 3.4Gbps. A common issue is exceeding the cable length limits: input and output runs are rated for 15 metres at lower resolutions but only 8 metres when running 4K signals.

Check source output and cable quality before

Verify that your source device can output 4K at 30Hz and that it complies with HDCP requirements. Use AWG26 standard HDMI cables and keep runs within the 8-metre 4K limit to avoid signal drop-out. This splitter mirrors only; it cannot show different images on each screen, so it is unsuitable for multi-monitor desktop extension setups.

Questions about this item

How can I verify the LUOM OZF4 is passing a 4K 30Hz signal correctly after connecting my source and four displays?

Check that all four screens show an identical 3840 x 2160 image at 30 Hz and that your AV receiver or soundbar reports DTS-HD, Dolby-trueHD, DTS, Dolby-AC3 or DSD audio.

What comes in the box with the LUOM OZF4 and which cables must I purchase separately?

The package includes the 1x4 HDMI splitter, a 5 V DC power supply and a user manual; you need to buy HDMI cables for the input and each of the four outputs.

Which LUOM OZF4 version should I choose for a 15 metre cable run at 4K resolution?

The single OZF4 model supports input and output cable lengths up to 8 metres at 4K, so for a 15 metre run you would need an active cable or fibre extender instead.
