OZJ2 4x2 HDMI 2.0b Matrix Switch Splitter 18.5Gbps 4K@60Hz HDR 3D HDCP2.2, 4 In 2 Out HDMI-Compatible Matrix with SPDIF Optical & 3.5mm L/R Stereo Audio Extractor for Game Consoles TV Monitor Projecto

This OZJ2 4x2 HDMI 2.0b matrix switch splitter is a professional multi-source AV signal routing device designed for home theater systems, conference rooms, classrooms and commercial display setups. Different from ordinary one-way HDMI switches, it adopts true matrix distribution architecture, enabling you to connect up to four HDMI signal sources and freely route each input to either or both of the two HDMI output displays. You can realize independent picture display on two screens or synchronous mirror output, perfectly solving the trouble of frequent plugging and unplugging messy HDMI cables when using multiple playback devices and dual monitors.

Complying with the official HDMI 2.0b standard and equipped with 18.5Gbps ultra-high transmission bandwidth, the matrix fully renders 4K@60Hz UHD resolution with YCbCr 4:4:4 color sampling, HDR high dynamic range image optimization and full 3D stereoscopic video effect, restoring rich color layers, sharp picture details and smooth frame motion for movies, games and live broadcasts. It is fully HDCP 2.2 compliant to eliminate black screen, playback failure or decoding errors when playing encrypted Blu-ray discs, streaming copyright videos and pay TV programs.

The core highlight lies in its independent audio de-embedding function. It can strip embedded digital audio from the selected HDMI video signal and output through two separated audio interfaces: SPDIF Toslink optical port for lossless 5.1 surround sound transmission to sound bars, power amplifiers and home theater speakers, and 3.5mm L/R analog stereo jack directly for headphones and desktop small speakers, greatly upgrading your immersive listening experience without occupying the audio channel of the display itself. It supports mainstream audio decoding formats including Dolby TrueHD, DTS-HD, AC3 and PCM 2.0 channel stereo, and comes with adjustable EDID mode to match different display and audio equipment automatically.

This matrix supports dual operation control methods: physical push buttons on the front panel for on-site quick switching, and a matched infrared remote control for remote wireless operation on the sofa or podium, greatly improving operation convenience. The whole body is wrapped in thickened aluminum alloy metal casing, which delivers excellent heat dissipation performance and effectively shields electromagnetic interference from surrounding power supplies, routers and electrical equipment, avoiding signal attenuation, screen flicker and audio noise during long-time continuous operation. The internal high-precision signal processing chip ensures zero delay switching without picture flashing or frame loss.

Wide compatibility covers nearly all HDMI-enabled audio video devices: PS5, PS4, Xbox Series game consoles, laptop & desktop computers, Blu-ray DVD players, TV set-top boxes, media streaming sticks, surveillance recorders, cameras, smart TVs, LCD monitors and projectors. It comes with a DC 5V power adapter for stable power supply, supports power-off memory function to lock the last routing setting after restart, and features compact size for easy placement in TV cabinets, conference equipment racks and multimedia workbenches. It is an indispensable cost-effective AV management accessory for audio-visual enthusiasts, office administrators and commercial AV engineering installers.
