 displays displays tell views where the output should go by adding a display to a view you can have your view appear as a page or as a block or even as an attachment to a different display on the view each display can have its own settings but when it s created a display will take all of its basic settings from the default display which all views must have for most settings there is an override button that will override that single setting for the current display overridden settings will have a mark in the summary for that display all default display settings are shown in the other displays  italic  when you override a setting than it is shown normal please keep in mind that when you are editing a setting on a display that is not overridden then by default you are editing that for all displays for fields   arguments   sorts   filters and relationships  you can only override all of them or none of them to do this click on the header for the filters or the rearrange button once you override the display will then have its own copies of the fields filters etc and changes to the defaults will not be reflected on your display
