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.

Questions about this item

How do I connect the Jansicotek 1x2 HDMI Splitter and which step do people often miss?

Connect the 5V/2A AC adapter to the DC 5V power port first, then plug the source into the single HDMI input and the two displays into the two HDMI outputs; the step most often missed is powering the unit before connecting video cables.

What maintenance or replacement will this splitter need over time?

The external 5V/2A AC adapter is the only replaceable part; the aluminum enclosure passively dissipates heat and contains no fans or batteries that require servicing.

What is the first limit I will hit when running 4K@30Hz signals continuously?

The HDMI 1.4 bandwidth ceiling of 10.2 Gbps caps you at 4K@30Hz and prevents 4K@60Hz or HDR at higher refresh rates regardless of cable length.
