SIIG 1x2 4K120Hz HDMI Splitter

The SIIG CEH27C11S1 distributes HDMI video and audio from one source to two displays simultaneously. It handles resolutions up to 4K at 120Hz with 40Gbps bandwidth and maintains HDCP 2.3 compliance. The metal housing supports stable, long-duration operation in professional environments.

Installers needing dual-display distribution

This splitter suits meeting rooms, lecture halls and digital signage where a single source must feed two screens. It extracts audio via Toslink and stereo outputs for separate sound systems. Buyers requiring more than two outputs or different video interfaces should consider alternative distribution hardware.

Sustained operation with firmware-update capability

The unit is built for continuous use in commercial settings such as restaurants, libraries and show rooms. A micro-USB port allows firmware updates to expand compatibility over time. EDID learning and resolution scaling between 1080p and 4K help maintain signal integrity during extended sessions.

Questions about this item

What source device and cables do I need to feed the 40Gbps HDMI input?

Connect any HDMI source — console, PC or media player — with an Ultra High Speed HDMI cable rated for 40Gbps to reach 4K at 120Hz.

Will my older 1080p display work alongside a new 4K120Hz screen on the two outputs?

Yes, the splitter downscales 4K to 1080p on one output while passing native 4K120Hz to the other, so both displays show the signal correctly.

How can I confirm the 4K120Hz VRR signal is passing through after setup?

Check the source device’s on-screen info or the display’s signal menu; both should report 4K at 120Hz with VRR and ALLM active.
