About ten years ago everyone at work started using dual monitors. It was great. But I switched to laptop for most tasks and do not have a second monitor. It occurred to me that I have a second screen right next to me (my phone) that I'm not using.
Is it possible to use it as a second monitor? I can imagine using it to show a training video while I follow along on the main screen.
I have a Mac and my phone is Android Galaxy 6S. I have an older iPhone 4S as well. Funnibly enough, my Android phone has higher resolution than my Macbook.
