Four-input HDMI multi-viewer

The LUOM OZQF is a 4×1 HDMI multi-viewer that connects four HDMI sources to a single display. It shows all four feeds at once using five split-screen layouts or switches seamlessly to any one source in full-screen mode. The unit supports resolutions up to 4096×2160 and handles 1080p at 60 Hz or 4K at 30 Hz. An IR remote, push-button and software control are included for source selection.

HDMI 1.4 ports and cable limits

Verify that each source and the display have HDMI 1.4 connectors compatible with the switch’s four inputs and one output. The specifications list AWG26 cable support with input runs up to 15 metres and output runs up to 15 metres. The box contains a DC power adapter but no HDMI cables, so you will need to supply five cables of suitable length. The remote ships without a battery.

Fanless operation and 12 V power draw

The aluminium chassis measures 200×93×20 mm and weighs 0.85 pounds, relying on passive cooling with no internal fan. In normal use the unit draws power from the included 12 V adapter and produces no audible noise. Heat output is low enough for desktop or rack placement without forced airflow.

Questions about this item

What comes in the box and do I need to buy HDMI cables or remote batteries separately?

The package includes the multi-viewer, IR remote, DC 12V power adapter and user manual. HDMI cables are not included and the remote does not come with a battery.

Which resolution mode should I choose between 4K30Hz RGB and 4K60Hz YUV forced output?

Use 4K30Hz RGB for full colour accuracy on a compatible display; 4K60Hz YUV is a forced-output mode that reduces chroma sampling to reach the higher refresh rate.

What does the 4K30Hz headline figure mean when I connect four sources to one screen?

Each input can run at up to 4096×2160 at 30 Hz; in split-screen modes the combined image is scaled to that single 4K30Hz output, so all four feeds appear simultaneously at the maximum resolution.
