Restricting campaigns based on minimum and maximum display width is only used in specific situations – it does not replace responsiveness, which is typically handled using breakpoints in the editor. This option is suitable when you need to completely exclude certain screen resolutions, for example in gaming campaigns or campaigns designed for specific devices such as point-of-sale terminals, information kiosks, or large-format displays.
A correctly set display width range ensures that the campaign will only be displayed where it visually and functionally matches the user's environment – and that it will not appear on devices for which it is not intended.
