4x4 HDMI Matrix Switch

The LUOM OZJ4 routes four HDMI sources to four independent displays, letting each output show a different source at the same time. It suits installations that need flexible distribution across multiple screens.

HDMI 2.0b bandwidth limits

The switch handles 18.5 Gbps and TMDS clock up to 600 MHz, supporting 3840×2160 at 60 Hz with YUV 4:4:4 and deep colour up to 24-bit. Cables must stay under 8 metres using AWG26 HDMI 2.0b spec to maintain signal integrity.

Check sources and displays first

Verify every source can output HDMI 2.0b with HDCP 2.2 and that each display accepts 4K at 60 Hz. EDID learning is available but may require a power cycle after configuration. No audio extraction ports are described in the data.

Questions about this item

Should I choose a 4x4 matrix or a simpler switch for four sources and four displays?

The 4x4 matrix lets any of the four inputs route independently to any of the four outputs, so each display can show a different source at the same time.

What does the 18.5Gbps bandwidth mean when I connect 4K@60Hz sources?

It carries full 4K@60Hz YUV4:4:4 and deep colour up to 12‑bit without compression, so HDR and 3D content pass through at native quality.

Does the HDMI 2.0b interface limit cable length at 4K@60Hz?

With AWG26 HDMI 2.0b cables the reliable run is under 8 metres; longer runs need active or fibre cables to keep the 18.5Gbps signal intact.
