ESTONE OZF14A 1×3 HDMI Splitter

The ESTONE OZF14A is a powered HDMI splitter that takes a single HDMI source and duplicates the signal to three displays simultaneously. It is designed for users who need to show identical content on multiple screens such as monitors, projectors or televisions. This unit does not support extended desktop modes so every connected display mirrors the same image. It suits home-theatre, gaming or digital-signage setups requiring simple signal distribution.

HDMI 1.4b limits and resolution behaviour

The splitter operates under the HDMI 1.4b specification with a maximum video bandwidth of 3.4 Gbps and a TMDS clock up to 340 MHz. It supports video resolutions up to 3840 x 2160 at 30 Hz as well as 1080p, 1080i, 720p, 720i, 480p and 480i. The output resolution is determined by the lowest common capability among all connected displays. Deep colour at 8, 10 or 12 bit is supported along with 3D video formats and HDCP 1.4 compliance.

Simple installation with included power supply

The package includes the splitter, a 5 V DC power adapter and a user manual. Connect the source device to the single HDMI input, attach up to three displays to the HDMI outputs and plug in the power supply. No drivers or software configuration are required. Common issues arise when cables exceed reliable lengths for the 3.4 Gbps data rate or when one display forces a lower resolution that limits the other outputs. Ensuring quality HDMI cables and matching display capabilities avoids most problems.

Questions about this item

This splitter only comes in a 1×3 version — is that the right choice if I need one source on three screens?

Yes, the 1×3 layout takes a single HDMI input and mirrors it to three identical outputs, so every connected display shows the same picture.

What does the 4K 30 Hz rating mean when I plug this into my TV and console?

The unit passes 3840×2160 at 30 Hz, so 4K video plays smoothly at that refresh rate; higher refresh rates or 4K 60 Hz are not supported.

The box says HDMI 1.4b — what does that limit in practice?

HDMI 1.4b caps the link at 3.4 Gbps and 340 MHz TMDS clock, which restricts 4K to 30 Hz and enables 8/10/12-bit deep colour and 3D formats.
