What the ESTONE OZF1 splitter does

The ESTONE OZF1 is a 1×2 HDMI splitter that takes a single source and sends an identical signal to two displays at the same time. It supports 4K at 30 Hz, 1080p at 60 Hz and 3D formats. The metal case houses an amplifier that extends cable runs up to 110 ft total. It is suited for installers who need mirrored output on two screens.

Installation and common issues

The unit is powered by an included adapter and works plug-and-play with no drivers required. Connect the source to the single input and the two displays to the outputs. EDID negotiation takes about four seconds. The most frequent issue is a mismatch when the two displays have different native resolutions; the splitter can only mirror, so the lower-resolution display dictates the output for both.

The specification that decides fit

Maximum resolution is 3840 × 2160 at 30 Hz with a bandwidth of 6.75 Gbps and HDCP 1.0 through 1.3 compliance. If your source or displays require 4K at 60 Hz or higher bandwidth, this splitter will not pass that signal. It is built for HDMI 1.4b mirror applications only.

Questions about this item

How can I confirm the OZF1 splitter is passing a 4K 30 Hz signal to both displays after setup?

Connect a 4K source and verify both screens show 3840 x 2160 at 30 Hz with matching 36-bit deep colour and HDCP 1.3 handshake.

What accessories are included with the OZF1 and which cables must I provide?

The box contains the splitter, a power adapter and a user manual; you must supply three HDMI cables — one for the source and one for each display.

Which OZF1 configuration should I choose for a 1080p 60 Hz gaming setup versus a 4K 30 Hz movie setup?

The single OZF1 model handles both: it supports 1080p at 60 Hz and 4K at 30 Hz simultaneously on its two outputs.
