- Samsung screen: The usual VGA/HDMI adapter
- iPad: Using DuetDisplay
Although there are some performance issues with Duet, to display text (which is what I do) is just fine. Now I can have the browser, the IDE (PyCharm if you are wondering) and iTerm 2.
Since is another screen attached to the laptop you can use it to display any other thing that is being processed by your main computer, and can move apps between the screens with no problem at all.
