===Television or computer monitor===
A [[TV]] or computer monitor typically comes with a button to "restore factory presets". This allows the settings for brightness, contrast, color, etc., to be returned to the defaults recommended by the manufacturer. This button may be used when the settings get badly adjusted (say by a toddler playing with the controls). Some "fine-tuning" of the settings may still be needed from the factory settings, but they will likely be closer to the desired settings than random settings.
