1x4 HDMI Splitter for 4K 30Hz Distribution

The LUOM OZF4C duplicates a single HDMI source across four displays at up to 3840 x 2160 resolution at 30 Hz. It supports HDCP 1.4 and passes audio formats including DTS-HD and Dolby TrueHD. The unit requires the included 5 V power adapter for stable operation.

Powered Setup with EDID Limitations

Connect the supplied 5 V 1 A adapter before linking sources and displays; the splitter will not function reliably without external power. Installation is straightforward plug-and-play, but the device only mirrors content — it cannot extend a desktop across screens. EDID handshake issues may arise if connected displays have mismatched capabilities.

Check Source Resolution

Verify that your source outputs 4K at 30 Hz or lower; higher refresh rates at 4K are not supported. The splitter handles HDCP 1.4 but will not pass HDCP 2.2 protected content such as many 4K streaming services. All four attached displays will show the identical image.

Questions about this item

How can I confirm the LUOM OZF4C splitter is passing 4K 30 Hz video to all four displays after I connect everything?

Power the unit with the included 5 V 1 A adapter, feed a 3840×2160 30 Hz source into the single HDMI input, then check each of the four HDMI outputs — all should show an identical picture at that resolution without flicker.

What ships in the box and do I need any extra cables or power bricks?

The package contains the 1×4 HDMI splitter, a 5 V 1 A power adapter and a user manual; you only need to supply five HDMI cables (one for the source, four for the displays).

Should I choose this OZF4C model or a different version for a 4K 60 Hz setup?

This OZF4C tops out at 3840×2160 30 Hz and supports HDCP 1.4 only, so it will not handle 4K 60 Hz or HDCP 2.2 sources — pick a splitter rated for 4K 60 Hz and HDCP 2.2 if you need those.
