The User Preferences window is accessed in the Main Display window through the Edit->Preferences menu. The Available Displays tab allows the user to specify what types of displays to use. The chosen displays can possibly be included in the Displays list in the Field Selector if the field you are displaying incudes the display type in its properties. Choosing what displays you want to appear in the Field Selector will limit the number of displays in the list, making it easier to create your desired image. The image below represents the default settings for the Available Displays tab. Every display is selected on by default.
