Could I use a USB Type-A adapter To connect the MST adapter with my computer if there is no USB-C port available?

Summary

No. The Plugable USBC-MSTH2 Dual HDMI MST Adapter requires a USB-C, USB4, or Thunderbolt port that supports DisplayPort Alternate Mode (DP Alt Mode) for video output.

Using a USB-A to USB-C adapter will not work because standard USB-A ports do not support DisplayPort Alt Mode. As a result, the USBC-MSTH2 will not provide video output through this connection.

Applicable To

  • Plugable USB-C Dual HDMI MST Adapter (USBC-MSTH2)
  • Computers without a USB-C port supporting DisplayPort Alt Mode

What Are My Alternatives?

If your computer only has USB-A ports, consider a Plugable USB graphics adapter that uses DisplayLink or Silicon Motion technology instead.

Compatible options include:

These adapters transmit video information over USB data connections rather than requiring DisplayPort Alt Mode.

Important Note: Both alternatives require compatible software or drivers and have their own operating system and display requirements. Verify compatibility with your computer before purchasing.
