4x2 HDMI Matrix Switch

The LUOM 4x2 HDMI Matrix Switch routes four HDMI sources to two displays with independent audio extraction. It suits home-theatre owners, installers and gamers who need simultaneous 4K output to a TV and a projector or a second monitor. The unit includes an IR remote for source selection and EDID control.

4K@60Hz and 18Gbps bandwidth

HDMI 2.0b chips deliver 4K@60Hz, 1080P and 3D with 8/10/12-bit deep colour and HDCP 2.2 at up to 18Gbps and 600MHz bandwidth. An automatic scaler down-converts 4K to 1080P when one display is limited to 1080P; other resolutions are not scaled. Both outputs can show different resolutions simultaneously when EDID is set to 0000.

SPDIF and 3.5mm audio extraction

Audio is de-embedded to Toslink SPDIF and 3.5mm stereo outputs at the same time, supporting LPCM 2.0/5.1, DTS and Dolby Digital. ARC return audio is also handled. The switch replaces a basic splitter plus separate audio extractor, making the upgrade worthwhile when you need matrix routing and multi-format audio breakout in one box.

Questions about this item

Will the LUOM 4x2 matrix pass 4K@60Hz from a PS5 to my older 1080P projector while keeping 4K on the main TV?

Yes, the scaler EDID lets a 4K source drop to 1080P on one output while the other stays at 4K@60Hz; set EDID to 0000 for simultaneous display.

How can I verify the matrix is switching sources and extracting audio correctly after I connect everything?

Use the IR remote to cycle the four inputs; check both displays show the selected source and confirm sound reaches your amplifier via the SPDIF optical or 3.5mm stereo outputs.

What cables and accessories come in the box with the LUOM OZJ2-1, and what must I provide?

The unit includes the matrix switch and an IR remote; you supply all HDMI cables for the four inputs and two outputs, plus an optical or 3.5mm cable for audio extraction.
