Today we will show you 2 methods to either mirror your screen, or extend it, on a Windows PC.

Uses of Duplicated or Extended Screens

Whether you decide to duplicate your screen or extend it, each of these has its own benefits. Usually, a user mirrors/duplicates their primary screen onto an external screen when they want to show the same to someone else besides themselves. For example, you have connected a massive 60″ TV as your secondary screen that is mounted on the wall for everyone to see, and you can play your advertisement or any video on both screens. If all your monitors are for your own use, then you can extend your display. This will allow you to use each screen individually and open different apps and windows across all of them. The extended screen display will increase your productivity. Now that you know which one you want, let us show you how to extend or duplicate your screen.

If you have the dual or triple-monitor setup in place but the Extend or Duplicate options still aren’t showing up, make sure that they are connected properly and to the right system ports.

How To Duplicate One Screen and Extend Another
