Why Are Both Monitors Displaying the Same Screen When My MacBook is Connected to This Dock?

When using our dock to connect a MacBook to dual monitors, please note that macOS devices only support screen mirroring in this configuration. This means both displays will show identical content.

 

Windows vs. macOS/iPadOS Compatibility:

 

1. Windows systems support both Single-Stream Transport (SST) and Multi-Stream Transport (MST), allowing extended or independent screens.

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