One-input four-output HDMI splitter

The LUOM OZF4C is a powered HDMI splitter that takes a single HDMI source and duplicates the signal to four HDMI displays at once. It handles video and audio together and supports resolutions up to 3840 x 2160 at 30 Hz, with backward compatibility down to 480i. The unit is intended for users who need the same picture on multiple screens in home, office or signage setups.

Included power adapter and manual

A 5 V 1 A power adapter ships in the box and must be connected for the splitter to operate reliably across all four outputs. The user manual provides basic connection guidance. No additional cables or mounting hardware are supplied, so you will need four separate HDMI cables to reach your displays.

Check source resolution and HDCP version

Verify that your source device can output at 3840 x 2160 30 Hz or one of the listed lower resolutions such as 1080P 60 Hz or 720P 60 Hz. The splitter supports HDCP 1.4 and 1.4b but does not support HDCP 2.2, so protected 4K content requiring the newer standard will not pass through. Also confirm that all four target displays accept the same resolution and refresh rate, because the splitter only mirrors and cannot extend the desktop.

Questions about this item

Will the included 5V/1A power adapter need replacement over time?

The unit ships with a 5V/1A power adapter; if it fails you can replace it with any 5V/1A supply that matches the barrel connector.

At 4K resolution the output is capped at 30 Hz — does that limit appear before bandwidth or heat issues?

The 30 Hz ceiling at 3840×2160 is a spec limit of the splitter itself, not a thermal or bandwidth throttle.

Does the splitter get hot or draw more power when driving four displays all day?

It runs from the supplied 5V/1A adapter and stays cool under normal continuous use with four HDMI outputs active.
