Step 1: Open the Windows display options by pressing the shortcut [Windows] + [P].
Step 2: You will see the various Windows options for using multiple screens. Use “Duplicate” to mirror the contents of the main screen or laptop to the second screen. To use only the second screen, the “Second Screen Only” function is a good choice. This is the right choice if you wanted to use a larger screen over the laptop.
Step 3: If you want to use two screens at the same time, the “Extend” function is helpful. If you select it, Windows will create a blank desktop on the second screen, or a contiguous desktop on two screens. Move the mouse beyond the right or left edge of the screen to reach the second screen. You can easily move program or browser windows between the screens.
