One-to-four HDMI distribution

The Jansicotek OZF4 takes a single HDMI source and mirrors it to four displays at once. It handles 4K at 30 Hz, 1080p and 3D content with supported audio formats including DTS-HD and Dolby TrueHD. The unit ships with a 5 V DC power adapter and requires no software setup.

4K 30 Hz maximum resolution

The splitter tops out at 3840 x 2160 at 30 Hz, so it will not drive 4K 60 Hz or higher refresh rates. HDMI 1.4 and HDCP 1.3 compliance means protected content plays on compatible sinks, but HDCP 2.2 sources may fall back to 1080p. Bandwidth is capped at 3.4 Gbps with a 340 MHz TMDS clock.

Plug-and-play with cable-length limits

Connect the source, attach up to four displays and apply power — no drivers needed. At 4K resolution the supplier rates input and output cables at 8 metres maximum; at 1080p the input can reach 15 metres and outputs 10 metres. Exceeding these distances often causes signal drop-out or no picture. The box only mirrors; it cannot extend a desktop across screens.
