DONGJIAN DVI Splitter 1 In 2 Out – 4K30Hz Dual Monitor Distribution

Overview

The DONGJIAN DVI Splitter 1 in 2 Out is a compact device designed to mirror a single DVI input across two displays. Both monitors show the same image, making it a practical choice for product showcases, demonstrations, classrooms, and conference rooms where synchronized content matters. The unit is plug-and-play, requiring no software or drivers, and is OS-agnostic, so it slots into existing setups with minimal fuss.

EDID Copy System for better compatibility: Output 1 acts as the copied port, helping maintain stable connections across a mix of displays. For best results, pair the lower resolution monitor with Output 1 to preserve alignment and clarity when content changes scale or timing.

High-resolution, lossless transmission: The splitter supports up to 4096x2160 at 30Hz, and can carry non-standard resolutions such as 2000x1000 at 60Hz without altering the original signal. There is no encoding or decoding of the DVI stream, which helps preserve image integrity for vivid details and sharp edges.

Long-distance signal transmission: Built for real-world environments, the device offers project-level signal amplification that enables about 10 meters of one-way transmission, with up to 20 meters total path length. This makes it suitable for larger rooms and staged presentations where a single source needs to reach multiple displays without degrade.

Everyday usability: The DVI Splitter is designed for immediate use—no software, no drivers, and no complicated setup. It remains a dependable option when quick content duplication across two screens is needed for meetings, product launches, or showroom tours.
