This depends on the casting technology and the application. Many casting methods, like Google Chrome’s built-in casting feature or dedicated apps like Netflix and YouTube, allow you to cast just the application window or even a specific tab. However, some methods, especially those using Miracast or AirPlay, might cast your entire desktop, including all open windows and notifications.
