4x4 HDMI Matrix for Multi-Display Setups

The LUOM OZJ7 routes four HDMI sources to four displays independently. Each output can also extract audio through optical or stereo connections. It suits installers, educators or AV enthusiasts who need flexible signal distribution without a dedicated processor.

Passive Cooling With Low Power Draw

The unit operates from -15 to +45 °C and 5 to 90 % humidity without a fan. Maximum working current is 500 mA at 5 V DC, supplied by the included 100-240 V AC adapter. Silent operation is assured in meeting rooms, classrooms or home racks.

Replaces Basic Splitters and Manual Switches

Unlike a 1-to-4 splitter, this matrix lets every screen show a different source. It upgrades setups where users physically swap cables or rely on single-output switches. The jump is worth it when four sources must reach four displays simultaneously with independent audio extraction.

Questions about this item

How do I install the LUOM 4x4 HDMI matrix and what step is often missed?

Connect up to four sources and four displays using HDMI cables no longer than 8 metres AWG26, plug the DC 5 V/2 A adapter into 100–240 V AC, then wait 3–5 seconds after each switch press for the signal to appear; the delay is normal, not a fault.

What maintenance or replacement will this matrix need over time?

The unit has no user-serviceable parts; keep ventilation clear so the operating temperature stays between –15 °C and +45 °C, use only AWG26 HDMI 1.4 cables under 8 metres, and replace the external 5 V/2 A power supply if it ever fails.

What limit appears first during sustained 4 K 30 Hz use?

The 10.2 Gbps bandwidth ceiling and 400 MHz TMDS clock restrict you to 3840×2160 at 30 Hz YUV 4:2:0; pushing higher refresh rates or full 4:4:4 colour will hit this ceiling first.
