4 In 2 Out HDMI 2.1 8K Matrix Switch Splitter, 4×2 HDR Video Matrix with IR Remote, 8K@60Hz 4K@120Hz CEC ARC Audio Extractor, SPDIF 5.1CH + RCA Stereo L/R Output HDCP2.3

This professional 4-input 2-output HDMI 2.1 matrix switch acts as a multi-signal central hub for home theater, gaming and conference systems. It supports flexible cross signal scheduling: you can output different video feeds on two displays separately, or copy identical synchronized images to both screens at the same time, far more versatile than ordinary single-way HDMI switches or simple mirror splitters. Adopting 48Gbps high-speed HDMI 2.1 chipset, it fully transmits lossless 8K@60Hz, 4K@120Hz, HDR10, Dolby Vision and 3D video content, retaining complete RGB color sampling and zero frame lag for competitive gaming and UHD movie playback. HDCP 2.3 full compliance ensures unblocked playback of all encrypted streaming and Blu-ray disc media. Multi-functional audio de-embedding design separates audio signals from video transmission independently. The SPDIF optical port outputs 5.1 -channel Dolby/DTS surround sound for soundbars and AV receivers, while RCA L/R stereo jacks output analog audio for headsets and desktop speakers. The ARC function pulls audio back from ARC-compatible TV to your audio equipment to simplify wiring layout. Customizable EDID adjustment module automatically matches native resolution parameters of connected monitors, TVs and projectors, eliminating manual setting and solving common compatibility faults like flickering screens and no signal. Matched IR remote enables one-click source switching from sofa or office distance; front panel buttons serve as spare control if remote fails.

Built-in signal retiming circuit offsets attenuation from long HDMI cables, and metal shielding blocks electromagnetic interference to maintain stable audio-video synchronization during all-day continuous operation. No complicated software installation required, just wire up 4 sources, 2 displays and audio devices to use instantly. Perfect for multi-game console home theater dual-screen setup, small meeting room multi-source presentation, commercial synchronous advertising multi-screen broadcast and high-end media player signal distribution scenes.
