LUOM OZJ4 4x4 HDMI Matrix

The LUOM OZJ4 is a 4x4 HDMI matrix switch that routes four HDMI sources to four displays independently. Each output can show any input or the same source across all screens. It supports HDMI 2.0b and HDCP 2.2 for protected 4K content. Infrared remote control and EDID management are included for straightforward operation.

Upgrade from basic splitters or manual switching

A simple splitter duplicates one source to every screen; this matrix lets each display choose its own source. The jump is worth it when you need simultaneous different content on multiple projectors or TVs from consoles, players or computers. It also replaces setups that require unplugging cables to change sources.

Check your cables and source capabilities

Use HDMI cables shorter than eight metres built to the HDMI 2.0b standard for reliable 4K at 60 Hz. Verify each source can output 3840x2160 at 60 Hz with YUV 4:4:4 or RGB 4:4:4 colour. Confirm your displays accept HDCP 2.2; older sinks without it will not show protected streams.

Questions about this item

How deep is the LUOM OZJ4 matrix switch so I can check it fits in my AV rack?

The unit measures approximately 230 mm long, 90 mm wide and 25 mm high, or 5.91 by 2.36 by 0.79 inches.

What is the correct sequence for setting EDID on the OZJ4 before use?

Select the desired EDID setting or learn from a connected display, then power-cycle the matrix switch so the new EDID takes effect.

How long can the HDMI cables be on the OZJ4 while still passing 4K@60Hz?

Use AWG26 HDMI 2.0b cables no longer than 8 metres for reliable 4K@60Hz transmission.
