4 In 2 Out HDMI Matrix Switch OZJ1 with IR Remote & EDID Management, 4K@60Hz 3D 1080P Video Splitter, Dual SPDIF Optical + Dual 3.5mm L/R Stereo Independent Audio Extractor

This OZJ1 4-input 2-output HDMI matrix switch realizes flexible cross signal distribution between four video sources and two display outputs. Users can set different video signals for the two screens separately or output identical synchronous images to fit multi-console gaming, home theater dual-screen entertainment and small conference multi-source presentation scenes. It is equipped with dual independent audio extraction channels, which can separate audio signals from video signals independently. Two SPDIF optical ports output digital surround sound for amplifiers and soundbars, while two 3.5 mm L/R stereo jacks provide analog audio for headsets and desktop speakers, supporting two sets of audio equipment working simultaneously.

The customizable EDID adjustment function automatically adapts to monitors with different native resolutions, effectively solving common problems such as no signal, screen flickering and color distortion caused by mixed-resolution displays. With high-speed transmission chip, it stably transmits 4K@60Hz ultra HD, 3D and 1080P video with intact color details without distortion or attenuation. A dedicated IR remote supports one-click channel switching from a distance; physical buttons on the front panel can be used when the remote is unavailable. Internal anti-interference shielding circuit prevents screen flicker, frame drop and audio static during long-time continuous operation.

No complicated software setup is needed, just complete wiring of sources, displays and audio devices to use immediately. Perfect for multi-game console home entertainment rooms, office multi-source presentation equipment and dual-screen commercial synchronous advertising playback.
