Windows 11 allows users to customize display timeout settings to prevent the screen from darkening when inactive. To adjust these settings via Settings, right-click the Start button, select "Settings," go to "Power & battery," expand the Screen, sleep, & hibernate timeouts section, and choose preferred times for both "Plugged in" and "On battery" options. Alternatively, users can adjust the timeout through the Control Panel by searching for "Control Panel," selecting "Hardware and Sound," clicking "Power Options," and changing the settings under "Change plan settings" for both battery and plugged-in options. Regular updates to Windows 11 are essential for optimal performance and security.
