4×2 HDMI Matrix Switch

The LUOM OZJ1 routes four HDMI sources to two independent displays, letting each screen show a different input or both mirror the same one. It suits home-theatre owners, meeting-room installers and anyone who needs simultaneous distribution without unplugging cables.

HDMI 2.0b bandwidth limit

The 18.5 Gbps link caps video at 4K 60 Hz RGB 8:8:8 with HDR10 and HDCP 2.2. Cable runs are reliable to 10 metres using AWG26 HDMI 2.0b cable; longer runs or higher refresh rates exceed the interface headroom.

Capacity and downscaling headroom

Two zones handle 4K 60 Hz and 2K 144 Hz sources comfortably, while the built-in scaler auto-downscales 4K to 1080p for older sinks. Ultra-wide 3440×1440 is not supported, and Dolby Atmos 7.1 is available only on output A.

Questions about this item

Should I choose the 4x2 matrix or a simpler switch for my four sources and two displays?

The 4x2 matrix lets you route any of the four inputs to either output independently, so both screens can show different sources at the same time.

What does the 18.5 Gbps bandwidth mean when I connect a 4K 60 Hz source?

It carries full 4K 60 Hz RGB 8:8:8 or HDR10 without compression, and the scaler can downscale automatically if one display only supports 1080p.

How does the HDMI 2.0b interface limit cable length and audio formats?

Certified cables up to 10 metres at AWG26 are supported, and the switch passes LPCM, DTS 5.1 and Dolby Atmos 7.1 through the HDMI and optical outputs.
