Disclosed are a picture adjustment method and apparatus for a video display appliance that can prevent an unskillful user from deteriorating a picture display state due to misadjustment of picture adjustment menus that cannot be easily adjusted and retrieved to the original state among a plurality of picture adjustment menus. According to the method and apparatus, a specified user selects and determines whether a plurality of picture adjustment OSDs, each of which includes a small number of picture adjustment menus, are accessible. A command for picture adjustment inputted through the picture adjustment OSDs that have been determined to be accessible only is processed to be effective, but a command for picture adjustment inputted through the picture adjustment OSDs that have been determined to be unaccessible is ignored. Thus, the misadjustment of the picture adjustment menus by an unskillful user can be prevented.
