Jansicotek 1x2 HDMI Splitter 4K@30Hz Aluminum

1×2 HDMI splitter for mirroring one source to two

This Jansicotek splitter takes a single HDMI input and duplicates it across two outputs so both screens show the same image. It supports 4K at 30 Hz, 1080p at 60 Hz and 3D formats, making it suitable for consoles, media players or PCs that need identical output on two monitors or televisions. The aluminium housing acts as a passive heatsink to keep the unit cool during continuous operation. An external 5 V, 2 A power adapter is included for stable signal transmission.

Passive aluminium cooling

The metal enclosure dissipates heat without a fan, so the splitter runs silently in normal use. Power draw is rated at 500 mA from the supplied DC 5 V adapter, keeping energy consumption low. Because the unit requires external power, it can drive longer cable runs — up to 100 ft total with AWG26 cable (40 ft input, 60 ft output) — without signal degradation. HDCP 1.4 bypass is supported for protected content playback.

Plug-and-play duplication for HDMI 1.4 sources

Connect the source to the single HDMI female input and two displays to the HDMI female outputs; no drivers or configuration are needed. The splitter works with HDMI 1.4, 1.3 and 1.2 devices but cannot pass 4K at 60 Hz or HDMI 2.0 and 2.1 signals. Audio formats including LPCM, Dolby AC3, DTS 7.1 and Dolby TrueHD or DTS-HD Master Audio pass through unchanged. Buyers who need independent extended desktops or higher refresh rates at 4K should consider a different solution.
