The screen on my MacBook Air is jumping around and I can’t control it. I have shut it down multiple times, doesn’t stop it from happening.
MacBook Air, iOS 10

Try hitting command-alt-8. If that doesn't work go to System Preferences>Accessibility>Zoom and unchecking all checkboxes. On older systems it's System Preferences>Universal Access>Seeing and turn off Zoom.
