You can adjust the displays brightness manually or automatically.

Use the brightness function keys

If the screen seems too light or too dark, you can adjust your displays brightness.

On your Mac, press [the Increase Brightness key] or [the Decrease Brightness key] (or use the Control Strip).

Automatically adjust brightness

If your Mac has an ambient light sensor, choose Apple menu []>System Settings, then click Displays [] in the sidebar. (You may need to scroll down.)
Open Displays settings for me
Turn on Automatically adjust brightness.

If you dont see the Automatically adjust brightness option, you can manually adjust the brightness.

Turning off auto-brightness may affect battery life, energy consumption and long-term display performance.

Manually adjust brightness

On your Mac, choose Apple menu []> System Settings, then click Displays [] in the sidebar. (You may need to scroll down.)
Open Displays settings for me
Drag the Brightness slider to adjust the brightness of your display.

Depending on the type of display connected to your Mac, you may also see a Contrast slider that you can use to adjust the displays contrast.
