1x4 HDMI Splitter 4K 30Hz

The LUOM OZF4 takes one HDMI source and mirrors it to four displays at once. It supports 3840 x 2160 resolution at 30 Hz and passes 3D video plus multi-channel audio formats including DTS-HD and Dolby TrueHD. The unit is powered by an included 5 V DC adapter and requires no drivers.

Interface bandwidth and cable limits

The splitter handles a maximum TMDS clock of 340 MHz and a data rate of 3.4 Gbps. With AWG 26 cables the input and output runs can each reach 15 meters at 1080p, but at 4K the reliable distance drops to 8 metres per leg. Deep colour at 8, 10 or 12 bit is supported within the same bandwidth ceiling.

Source and display checklist

Verify that your source device outputs HDMI 1.4b or compatible 2160p30 signals and that all four target displays accept the same mirrored resolution. The box only duplicates the image; it cannot extend a desktop across screens. Ensure the 5 V power supply is connected before use.

Questions about this item

Should I choose this 1x4 HDMI splitter or a 4x1 switch for my setup?

Pick this 1x4 splitter when you need one source — such as a Blu-ray player or game console — mirrored to four displays; choose a 4x1 switch only if you want four sources feeding one screen.

What does the 4K 30 Hz rating mean when I connect it to my TV?

The unit passes 3840 x 2160 resolution at 30 Hz, so 4K video plays smoothly but high-refresh-rate gaming above 30 Hz is not supported.

Which HDMI version does the splitter use and what bandwidth limit applies?

It complies with HDMI 1.4b and caps the data rate at 3.4 Gbps with a TMDS clock up to 340 MHz.
