How to Configure Displays in Duplicated and Extended Modes

  • Duplicated – The desktop is duplicated (including resolution) on more than one display. This setup can be useful for running demos and presentations.
  • Extended – The desktop is extended across multiple displays. Each extended display has its own unique desktop area (including screen resolution and refresh rate). This setup can be used to provide additional desktop space.

To set up Duplicate mode:

  1. Right-click on an empty area on the Desktop, and select Display Settings from the menu
  2. In the Displays Setting menu, it should list all detected displays (in the example below, 2 displays are used).  Click on the Multiple Displays drop-down menu, and select Duplicate these displays.
  3. Click Apply
  4. Click Keep changes button

Enabling Extended Desktop

How to Enable Extended Desktop Mode
