What it is and who it serves

The Jansicotek OZF3 is a 1×4 HDMI 2.0b splitter that takes one source and duplicates it to four displays at up to 4K 60 Hz with 18.2 Gbps bandwidth. It supports HDR10, Dolby Vision, HDCP 2.2 and EDID management for reliable handshakes. The aluminium enclosure measures 5.59 × 3.15 × 1.26 inches and weighs 3.2 ounces, and a power adapter is included.

Who this suits and who should look elsewhere

Installers needing the same image on four screens — such as digital-signage walls, multi-room TV setups or simultaneous projector and monitor feeds — will find the four HDMI outputs and wide 25 MHz–600 MHz frequency range convenient. Buyers who want independent extended desktops, additional inputs or switching between sources cannot use this unit because it only mirrors a single input.

The specification that decides fit

Maximum supported resolution is 3840 × 2160 at 60 Hz with 18.2 Gbps throughput and HDCP 2.2 compliance. If the source or any display requires higher bandwidth — for example 4K at greater than 60 Hz — the splitter will not pass the signal, so confirm the source output matches these limits before purchasing.

Questions about this item

Does the splitter generate noticeable heat or fan noise during continuous all-day operation?

The aluminium enclosure passively dissipates heat; there is no fan, so operation is silent and temperatures stay low even with 18.2 Gbps throughput.

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

You need one HDMI cable from the source to the input, four HDMI cables to the displays, and a nearby mains socket for the included 5 V power adapter.

Will my older 1080p monitors and HDCP 1.4 AV receiver work with the HDCP 2.2 handshake?

Yes, the splitter converts HDCP 2.2 down to 1.4 and passes 1080p at 60 Hz, so legacy screens and audio gear remain compatible.
