Jansicotek OZF1 HDMI Splitter 1x2

The Jansicotek OZF1 is a powered HDMI splitter that takes one HDMI source and duplicates the signal to two HDMI displays simultaneously. It supports video resolutions up to 4K at 30 Hz and 1080p at 60 Hz, along with 3D content and 36-bit deep colour. An included AC adapter provides the power needed for signal amplification over longer cable runs.

Suits duplication only — not extension

This splitter suits users who want the same image mirrored on two screens, such as a living-room TV and a bedroom display, or a projector and a monitor showing identical content. It does not support extended desktop modes where each screen shows a different part of the workspace. Buyers needing independent displays or more than two outputs should look at a different product type.

Maximum resolution 3840 x 2160 at 30 Hz

The single specification that decides compatibility is the 4K 30 Hz output limit. If the source device and both displays operate at 3840 x 2160 resolution with a 30 Hz refresh rate, the splitter will pass the signal correctly. Sources or displays that require 4K at 60 Hz or higher refresh rates will not work at their native capability through this unit.

Questions about this item

Should I pick the OZF1 1x2 model or look for a version with more output ports?

The OZF1 is a 1x2 splitter with one HDMI input and two HDMI outputs. If you need to send the same signal to only two displays this model fits; more outputs would require a different unit.

What does the 4K@30Hz headline mean when I connect a 4K TV and a 1080p monitor at the same time?

Both outputs mirror the source. The splitter supports up to 3840×2160 at 30 Hz, so a 4K TV will show 4K@30Hz while the 1080p monitor receives a 1080p@60Hz signal downscaled from the same stream.

The box says HDMI 1.4b and 6.75 Gbps bandwidth — what resolution and cable length does that cap in practice?

HDMI 1.4b with 6.75 Gbps limits the maximum to 4K@30Hz or 1080p@60Hz. The manufacturer rates input cables up to 50 ft and output cables up to 60 ft at 1080p; 4K distances will be shorter.
