I am trying to use an iPad as a second screen/monitor. The instructions said go to System Preferences>Displays and open the "Arrangement" tab. I do not have an arrangement tab.
See if you still have this option >System Preferences>Displays
press the Option key while you're in Displays— You'll get a Detect displays button (bottom right).
there is a checkbox "Show displays in menu bar". If you check it, you get a new icon in the menu bar that has "Detect Displays" as its first option.
