ESTONE OZF8K1 HDMI 2.1 Splitter 1x2 8K 60Hz 4K 120Hz

What this splitter does

The ESTONE OZF8K1 is a powered HDMI 2.1 splitter that takes one HDMI source and duplicates the signal to two identical displays or a display and a soundbar. It supports resolutions up to 8K at 60 Hz and 4K at 120 Hz with RGB 4:4:4 colour and HDR. The unit also handles 1440p at 144 Hz and 1080p at 240 Hz for high-refresh gaming. Audio formats including Dolby Atmos, Dolby TrueHD and DTS-HD pass through without processing. It is suited for users who need the same image on two screens simultaneously.

Check your cables and source

Before ordering, verify that your source device and both displays have HDMI ports and support the resolutions you intend to use. The splitter requires a DC 5 V power adapter, which is included, so ensure a mains socket is available near the install location. Maximum supported cable run is 26 ft total, with up to 16 ft on the input side and 10 ft on each output. The box contains the splitter, the power adapter and a user manual. No software or driver installation is needed.

Heat, noise and power in use

The aluminium enclosure acts as a passive heatsink; the unit runs warm but stays within safe limits during continuous 8K 60 Hz operation. There are no fans, so operation is completely silent. Power draw is low, supplied by the included 5 V adapter, and the device does not add measurable load to the source. EDID management takes about 4 seconds at power-up, after which the signal is stable. Daisy-chaining additional splitters is supported for larger distributions.
