Mirror-only 1×4 HDMI Splitter

The LUOM OZF4 takes a single HDMI source and sends the same 4K 30 Hz picture to four displays at once. It is built for installers, retailers, or home users who need identical content on every screen without configuring extended desktops. A 5 V DC adapter is included so the unit can drive cables up to 15 metres at 1080p.

Not for multi-room switching or desktop extension

Buyers who want to pick between several sources or show different images on each monitor should choose a matrix switch or a graphics card with multiple outputs. This device only duplicates one incoming signal and cannot blend or route independent streams.

4K 30 Hz ceiling with 3.4 Gbps bandwidth

The splitter passes 3840 × 2160 at 30 Hz and tops out at 3.4 Gbps with a 340 MHz TMDS clock, so higher refresh rates or 4K 60 Hz material will not pass through. Check the source and display specifications against that limit before purchasing.

Questions about this item

Will the 5 V DC power supply need to be replaced after extended use?

The splitter ships with a 5 V DC adapter; no user-replaceable parts are inside, so the only item that could wear out is the external supply itself.

What cable length limit appears first when running 4 K at 30 Hz?

At 4 K resolution the input and output cables are each limited to 8 metres, which is the first restriction you hit under sustained use.

How much heat or noise does the unit produce when powered all day?

The device has no fan and draws little power, so it runs silently and stays only slightly warm during continuous operation.
