Summary
The Plugable USBC-MSTH2 Dual HDMI MST Adapter can provide video output on compatible Mac computers. However, it is not recommended for Mac users who want to connect two independent extended monitors.
This is because macOS does not support Multi-Stream Transport (MST) for multiple independent extended displays, which is the technology the USBC-MSTH2 uses.
Applicable To
- Plugable USB-C Dual HDMI MST Adapter (USBC-MSTH2)
- Mac computers running macOS
What to Expect
When connected to a compatible Mac:
- One external monitor can extend the Mac's desktop.
- A second monitor connected through the adapter will mirror the first external monitor.
- Two independent extended external displays are not supported through this adapter.
If your goal is to add two independent external monitors to your Mac, the USBC-MSTH2 is not the right solution.
Instead, consider a compatible Plugable DisplayLink adapter or docking station, which can support multiple extended displays on compatible Macs with the required software.
For additional specifications, see the Plugable USBC-MSTH2 Product Page.
