4x4 HDMI Matrix Switch 4K@60Hz

The LUOM OZJ4 is a 4x4 HDMI matrix switch that routes four HDMI sources to four HDMI displays independently. It supports HDMI 2.0b and HDCP 2.2 with a maximum bandwidth of 18.5 Gbps. The unit handles video up to 3840x2160 at 60 Hz with YUV 4:4:4 colour sampling and deep colour up to 24 bit. An IR remote control is included for switching operation.

Installers needing any-to-any 4K distribution

This matrix suits installers who need to switch or split four sources across four screens with independent routing per output. It also provides independent audio extraction via optical or stereo outputs on each port. Buyers who require more than four inputs or outputs should look at larger matrices. Users needing HDMI 2.1 features such as 4K at higher refresh rates or variable refresh rate will not find those capabilities here.

18.5 Gbps bandwidth at 4K 60 Hz 4:4:4

The single specification that decides fit is the 18.5 Gbps bandwidth limit, which enables full 4K 60 Hz 4:4:4 signals but excludes higher-resolution or higher-refresh-rate formats. Cable runs must stay under 8 metres using AWG26 HDMI 2.0b cables to maintain signal integrity. EDID management with learning and presets helps maintain compatibility across mixed source and display combinations.

Questions about this item

How can I confirm the matrix is passing 4K@60Hz YUV4:4:4 after setup?

Check the source and display info menus — both should report 3840x2160 at 60 Hz with 4:4:4 chroma and deep-color 8/10/12-bit; the front-panel LEDs will show active links on all four inputs and outputs.

What comes in the box and what must I provide?

The package includes the 4x4 matrix unit, IR remote and power supply; you supply four HDMI source cables and four HDMI display cables, each under 8 m AWG26 rated for HDMI 2.0b.

Which EDID mode should I select for a mixed 1080p and 4K display setup?

Use the EDID learning function to copy the timing from the 4K display, then restart the matrix; this forces all sources to output 3840x2160@60Hz while the 1080p screens down-scale automatically.
