One-to-four HDMI distribution

The Jansicotek OZF4C is a powered HDMI splitter that takes a single HDMI source and duplicates it to four displays simultaneously. It transmits video and audio together without signal loss and supports HDCP 1.4b and 1.4. The unit is intended for installers, educators, or home users who need identical content on multiple screens.

Powered operation and cable limits

A 5 V 1 A power adapter is included and must be connected for reliable operation. The supplier notes that input cable distance should stay under 5 metres for 1080p signals and under 10 metres for 1080p at lower bandwidth. The splitter does not extend or switch displays; it only mirrors the incoming signal to all four outputs.

Steps up from basic one-to-two splitters

This model replaces a simple 1×2 splitter when four outputs are required, or an unpowered adapter that cannot drive longer cable runs. The jump is worth it when a single source such as a game console, streaming stick, or Blu-ray player must feed four monitors, projectors, or TVs at up to 4K 30 Hz without HDCP 2.2 content.

Questions about this item

Does the 30 Hz ceiling at 4K limit smooth motion during long viewing sessions?

The splitter caps 4K output at 30 Hz, so fast motion may show judder during extended use; 1080p at 60 Hz remains available for smoother playback.

How warm does the unit get and does the fan make noise when powered all day?

The device has no fan and draws 5 V at 1 A; it runs warm to the touch but stays silent during continuous operation.

Which HDMI cables and power source must I already have to connect four displays?

You need five HDMI cables — one from the source to the splitter and four from the splitter to each display — plus a mains socket for the included 5 V 1 A adapter.
