One-to-three HDMI splitter for mirroring

The LUOM OZF14A takes a single HDMI source and duplicates it across three displays simultaneously. It supports 4K resolution at 30 Hz and HDMI 1.4b signals, making it suitable for media players, consoles or security cameras. The unit does not offer an extended desktop mode, so every connected screen shows the same image.

Passive operation with external power

The splitter draws power from an included 5 V DC adapter rather than the source device. It handles TMDS clock rates up to 340 MHz and a maximum bandwidth of 3.4 Gbps. Deep-colour support at 8, 10 and 12 bit is maintained across all outputs without active cooling or audible noise.

Bundled power supply and manual

A 5 V DC power supply is provided so the splitter works immediately without sourcing a separate adapter. The package also includes a user manual for installation guidance. Input cables up to 15 metres and output cables up to 15 metres are supported at lower resolutions, while 4K signals are reliable up to 8 metres on each side.

Questions about this item

How do I install the LUOM OZF14A 1×3 HDMI splitter and what is the step people often get wrong?

Connect the 5V DC power supply first, then link one source to the single HDMI input and up to three displays to the HDMI outputs; the step many miss is powering the unit before attaching any cables, otherwise no signal appears on the screens.

What maintenance or replacement will the LUOM OZF14A splitter need over time?

The external 5V DC power adapter is the only part likely to wear out; if the splitter loses signal on all three outputs simultaneously, replace the adapter with another 5V unit of equal or higher amperage.

What limit appears first when running the LUOM OZF14A at 4K 30 Hz for long periods?

The HDMI 1.4b bandwidth ceiling of 3.4 Gbps and 340 MHz TMDS clock caps sustained 4K 30 Hz transmission; cable runs beyond 8 metres on either input or output will then degrade the signal.
