Why do this? If you’re trying to preserve laptop battery life while giving a presentation, this will help.

If you’re using a second monitor, however, I recommend clicking Extend, which literally expands the desktop so you can open extra windows (a common example is running your Web browser on one screen and your word processor on the other).įinally, there’s Projector only, which turns off your laptop’s LCD, effectively turning the projector into your monitor. That’s handy during presentations and other situations when you’re still working at the computer. Click Duplicate and Windows will clone your screen to whatever secondary display is connected, monitor or projector. By default, the mode is set to Computer only.
