icon in the taskbar and then select or deselect Disable On Screen Brightness Meter to enable or disable the Brightness Meter on the screen.

NOTE:

By default, the Brightness Meter appears in the lower-right corner of the display when you use the keyboard shortcuts to adjust display

brightness. You can click and drag the meter to a preferred location.
