To project to a second screen, you can search the Start Menu for "Project to a second screen". Use the Windows Start menu button in the lower left hand corner of your desktop screen. You can also access the display menu by pressing the Windows button and the 'P' key at the same time.
There are several different options to chose from:
1) "PC Screen Only" uses only the computer's main display.
2) "Duplicate" creates a copy of what is on your main display on the secondary display.
3) "Extend" is an extension of your current display on the secondary display, allowing for an additional space where you can place content.
4) "Second Screen Only" uses just the secondary display.
