Why Do Both Monitors Show the Same Screen When My MacBook is Connected to This Dock?


  • When using this dock to connect a MacBook to dual monitors, please be aware that macOS only supports screen mirroring in this setup. This means both displays will show the same content.  

    Windows vs. macOS/iPadOS Compatibility:

    1. Windows Systems – Support both Single-Stream Transport (SST) and Multi-Stream Transport (MST), enabling extended or independent displays.  

    2. macOS and iPadOS – Only support Single-Stream Transport (SST). As a result, dual monitors connected through this dock will mirror the same image.
