How do I make the display on my laptop brighter?

If you have a laptop, you might need to occasionally change the screen brightness. For example, if you want to use your laptop outdoors on a sunny day, you might need a brighter screen to see the display clearly. Or, if you're in a dark room, you might want to make the screen less bright.

Note

  • A brighter display uses more power, which reduces battery life.

  1. Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

  2. Move the slider next to Screen brightness at the bottom of the screen. The brightness changes automatically.

Note

  • If the Screen brightness slider isn't available, your laptop might not support brightness adjustment or you might need to update your display drivers. For more information, see Update drivers: recommended links.
