If you are a developer or a video editor, you can extend iPad as the second screen of your Windows or Mac.

Use iPad As A Second Screen for Mac

Even though both the Apple iPad and Mac devices (iMac or MacBook) come under Apple’s branding, they do not allow you to share screen or even the files across in just click. Therefore, it is not going to be a single click choice if you are looking for an in-built option to share the screen and extend the display for your Mac. The MacOS does not have an inbuilt feature to let you connect with the iPad over the lightning cable and share the display.
