LUOM OZJ4 4x4 HDMI Matrix Switch

The LUOM OZJ4 routes four HDMI sources to four independent displays. Each output can show a different source or mirror any input. It handles 4K at 60 Hz with 18.5 Gbps bandwidth and HDCP 2.2 compliance.

Installers needing true matrix routing

This unit suits AV racks, conference rooms and multi-room setups where every display must choose its own source. It is not for users who only need one source duplicated across several screens; a simple splitter would cost less.

4x4 matrix with 4K 60 Hz 4:4:4 support

The decisive spec is the full 4x4 crosspoint switching at 3840×2160 60 Hz YUV 4:4:4. If your installation requires fewer inputs, fewer outputs, or only 30 Hz 4K, a smaller or lower-bandwidth switch will do the job.

Questions about this item

Do I need HDMI 2.0b cables rated for 18 Gbps to get 4K at 60 Hz from the LUOM OZJ4?

Yes. The matrix supports HDMI 2.0b and 18.5 Gbps bandwidth, so each source and display needs a certified 18 Gbps cable no longer than 8 metres to pass 3840x2160 at 60 Hz YUV 4:4:4.

Will my older 1080p projector work on the same output as a new 4K HDR TV?

Yes. The OZJ4 includes EDID management that can learn each display or use preset EDIDs, so a 1080p projector and a 4K HDR TV can share the matrix without forcing the 4K source down to 1080p.

How can I confirm the matrix is passing 4K 60 Hz HDR to a specific display after setup?

Use the IR remote to select that output, then check the source device’s info menu — it should report 3840x2160 at 60 Hz with HDR and HDCP 2.2 active.
