Matrix Display is a MSI exclusive technology which supports the Multi-display Mode and the Surround View Mode.
The Multi-display Mode provides multiple displays shown on multiple monitors (including the build-in display) individually. Find the maximum display support and the setup guide in our FAQ (https://www.msi.com/faq/notebook-1661, https://www.msi.com/faq/notebook-1438).

The Surround View Mode supports the display across multiple monitors at once. *Note: Not every MSI notebook supports Surround View, find the support list and the setup guide in our FAQ (https://www.msi.com/faq/notebook-1661, https://www.msi.com/faq/notebook-1424).
