One-to-two HDMI splitter

The ESTONE OZF1 takes a single HDMI source and duplicates the signal to two displays at the same time. It is a powered unit that buffers and amplifies the signal so longer cable runs stay stable. The box includes the splitter, a power adapter and a user manual.

HDMI 1.4b bandwidth ceiling

The splitter operates on the HDMI 1.4b interface with a 6.75 Gbps bandwidth limit. That ceiling restricts 4K output to 30 Hz and 1080p to 60 Hz while still passing deep-colour 36-bit video and multi-channel audio formats such as Dolby TrueHD and DTS. HDCP 1.0 through 1.3 are supported for protected content.

Mirror-only duplication

This device only mirrors the same image to both outputs; it cannot extend a desktop or show different sources on each screen. Buyers who need independent displays or a matrix switch should look for a different class of product.

Questions about this item

The OZF1 is a single 1x2 model — is there any capacity or version choice to make?

No — the OZF1 is a fixed 1-input, 2-output HDMI splitter with an included power adapter.

The box says 4K at 30 Hz — what does that actually deliver when I plug it in?

It mirrors one source to two displays at up to 3840 x 2160 pixels at 30 Hz, or 1080p at 60 Hz, with 3D support.

The spec lists HDMI 1.4b and 6.75 Gbps bandwidth — what does that cap in practice?

It limits you to 4K 30 Hz 8-bit or 1080p 60 Hz; higher refresh rates or 4K 60 Hz need HDMI 2.0 bandwidth.
