4×1 HDMI Multi-Viewer for four sources

The LUOM OZQF accepts four HDMI 1.4 inputs and routes them to a single HDMI 1.4 output. It is built for users who need to monitor security cameras, consoles, PCs or streaming devices on one display without constantly swapping cables. Five layout modes — full screen, quad split, horizontal, vertical and one-large-plus-three-small — cover both simultaneous viewing and focused work.

Sustained operation with seamless switching

In full-screen mode the unit switches between the four inputs without the usual five-to-eight-second handshake delay, so a control-room operator or gamer can jump from source to source instantly. The built-in scaler handles 720p, 1080p and 4K signals at 30 Hz, up-scaling or down-scaling each feed to match the output timing continuously during long sessions.

Passive cooling and 12 V DC power

The metal enclosure measures 8.39 by 3.94 by 0.98 inches and weighs .85 pounds, dissipating heat without a fan for silent operation. A supplied 12 V DC adapter powers the device, and the specification rates HDMI cable runs up to 15 metres on both input and output sides using standard AWG26 wiring.

Questions about this item

Does the LUOM OZQF run hot or make noise when left on all day?

The unit is passively cooled with no fan, so it stays silent and only warm to the touch during continuous operation.

What cables and power source must I already have to use this 4×1 multi-viewer?

You need four HDMI source cables up to 15 metres each, one HDMI display cable up to 15 metres, and a nearby mains outlet for the included DC 12 V adapter.

Will my older 1080p security camera and 720p Blu-ray player work alongside a 4K Fire Stick on the same screen?

Yes — each HDMI 1.4 input accepts 720p, 1080i, 1080p or 4K@30 Hz signals, and the built-in scaler matches them to the chosen output mode.
