This 4-input 2-output HDMI 2.1 matrix switch realizes flexible cross signal distribution between four signal sources and two display terminals. You can set different video content on the two screens separately to expand multi-task workspace, or output identical synchronized images on both displays for simultaneous viewing, ideal for multi-game console home theater, dual-screen office and commercial multi-screen broadcasting. Adopting 48Gbps high-speed HDMI 2.1 chip, it stably transmits top-tier UHD content including 8K@60Hz and smooth 4K@120Hz high frame rate gaming, retaining complete lossless RGB color sampling and layered HDR light shadow details without color banding or distortion.

HDCP 2.3 certification ensures unblocked playback of all copyrighted streaming and Blu-ray encrypted media. Built-in multi-functional audio processing module separates audio signals from video signals independently. SPDIF optical port outputs 5.1 -channel Dolby/DTS surround sound for AV receivers and soundbars; L/R stereo jack fits headsets and desktop speakers. ARC function extracts audio from ARC-supported TV back to your audio equipment to simplify wiring layout. Custom adjustable EDID management automatically matches native resolution parameters of connected TVs, monitors and projectors, effectively solving common compatibility issues such as black screen, screen flicker and handshake failure.

Matched wireless IR remote supports one-click source switching from a distance; physical buttons on the front panel serve as spare control when the remote is missing or out of power. Internal anti-interference shielding circuit offsets signal attenuation of long HDMI cables, avoiding frame drop, color shift and audio static during long-hour continuous operation. No complicated software installation required, just connect power adapter, four signal sources, two displays and audio devices to complete setup instantly. Ideal for multi-console gaming home theater, meeting room multi-source presentation, shopping mall dual-screen advertising broadcast and graphic design dual-monitor workstation expansion.
