4K HDMI Splitter 1 in 2 Out, Aluminum Alloy 1x2 HDMI Splitter with 4 FT HDMI Cable, Mirror Only (Duplicate One Source to Two Screens), 1080P@60Hz & 4K@30Hz, EDID Control, for TV, Monitor, Projector

Additional Technical Specifications, Installation & Use GuideThis HDMI splitter is designed for stable 1-in-2-out mirror distribution, ensuring the same content is displayed simultaneously on two screens. It is suitable for both commercial and home environments where synchronized display is required.Recommended HDMI Cable Length For 1080P@60Hz, stable transmission is recommended within 26ft. For 4K@30Hz, recommended distance is up to 10 ft, depending on cable quality and device compatibility.HDMI Cable Requirement For best performance, use HDMI 2.0 cables with AWG 26 or higher. High-quality shielding helps reduce signal loss, flicker, or intermittent black screen issues in dual-display setups.Power Supply Recommendation A 5V/1A external power adapter is strongly recommended for stable dual-screen output. Insufficient power may cause unstable signal transmission when both outputs are active. This HDMI splitter is widely used in multiple environments requiring synchronized display output: Retail & Digital Signage – Display the same promotional content on two screens in storefronts, shopping malls, or exhibition booths to attract customer attention more effectively.Education & Training – Share identical teaching content to students on different screens in classrooms, training centers, or lecture halls.Corporate & Business Meetings – Mirror presentations simultaneously on a main display and a secondary monitor or projector for clearer visibility in conference rooms.Home Entertainment – Output the same movie, sports event, or gaming content to two TVs or projector setups for shared viewing experiences.Religious & Public Venues – Suitable for churches, halls, or event spaces where synchronized visual content is required for larger audiences.Signal Stability Note EDID management helps improve compatibility between displays, but overall performance still depends on source device capability, cable quality, and power stability. Using certified HDMI cables and proper power supply significantly enhances reliability.Important Reminder This is a mirror-only HDMI splitter and does not support extended display, ARC/eARC, or audio extraction functions.
