1-in-2 HDMI splitter for 4K@60Hz sources

The ESTONE OZF2-1 takes a single HDMI 2.0b input and duplicates it to two displays at up to 3840 x 2160 resolution and 60 Hz refresh. It passes 24-bit, 30-bit and 36-bit deep colour plus HDR, and carries audio formats including DTS-HD, Dolby TrueHD and DSD HBR. The unit is powered by an included USB cable, requires no drivers and fits easily in a travel bag.

Sustained signal integrity at 18.5 Gbps bandwidth

The splitter maintains the full 18.5 Gbps data path without compression or frame drops during continuous playback of 4K@60Hz 4:4:4 content. Deep-colour bit depths of 30-bit and 36-bit remain stable over long sessions, and HDCP 2.2 handshakes do not time out. Audio streams such as Dolby TrueHD and DTS-HD pass through without audible glitches or lip-sync drift.

Verify your source and displays before ordering

Confirm the source device outputs HDMI 2.0b or earlier and can drive 4K@60Hz or 1080p@120Hz without requiring CEC control, because the splitter does not pass CEC commands. Both connected displays must accept the same resolution and refresh rate, as the unit only mirrors and cannot extend desktops. Ensure a free USB port or 5 V charger is available to power the splitter via the supplied cable.

Questions about this item

Does the 18.5 Gbps HDMI 2.0b splitter generate noticeable heat or fan noise during all-day operation?

The OZF2-1 is a passive, fan-less device that draws power only from the included USB cable, so it runs silently and stays cool even when driving two 4K@60 Hz displays continuously.

What must I already own to use this splitter out of the box?

You need a single HDMI 2.0b source, two HDMI displays, three HDMI cables and a USB power adapter or powered port for the supplied USB cable; the box contains the splitter, USB cable and manual only.

Will the splitter down-scale 4K@60 Hz to 1080p on an older 1080p TV while keeping 4K on the other display?

No — the unit mirrors the same EDID to both outputs, so both screens must accept the incoming 4K@60 Hz signal; a 1080p-only display will show no picture.
