1x2 HDMI splitter for dual-display mirroring

The ESTONE OZF1 takes a single HDMI source and duplicates it to two screens simultaneously. It supports 4K resolution at 30 Hz and 1080p at 60 Hz with 3D capability. The powered unit includes signal amplification for extended cable runs up to 110 feet total distance. It is suited for home theatre, digital signage or presentation setups requiring identical output on two displays.

Signal stability over long cable runs

The splitter buffers and amplifies the HDMI signal to maintain integrity across distances of up to 60 feet from source to splitter and 50 feet from splitter to each display. It complies with HDMI 1.4b and HDCP 1.0 through 1.3 for protected content playback. Deep colour support at 30, 36 and 48 bits per pixel preserves gradient detail during sustained operation. Audio pass-through covers LPCM 7.1, Dolby TrueHD, DTS-HD and other common formats.

Mirror-only output constraint

This device operates exclusively in mirror mode, sending the same image to both outputs with no support for extended desktop or independent display configurations. Buyers who need separate content on each screen or a matrix switching function should select a different product class. The 4-second EDID handshake duration is fixed and cannot be adjusted for faster switching scenarios.

Questions about this item

Does the ESTONE OZF1 run hot or draw much power when it duplicates a 4K 30 Hz signal all day?

The splitter is powered by an external adapter and has no fan, so it stays cool and draws minimal power during continuous operation.

Which cables and power source must I already have to use this 1×2 HDMI splitter?

You need one HDMI cable from your source to the input, two HDMI cables to the displays, and a wall outlet for the included power adapter.

Will the OZF1 pass 1080p 60 Hz and 3D from an older PS3 or Blu-ray player to two modern monitors?

Yes, it supports 1080p at 60 Hz, mandatory 3D formats and HDCP 1.0–1.3, so legacy sources work with current displays.
