iMod mentioned Duet Display a couple of days ago – I have an unused iPad Air and no real use for it, so I took Duet Display for a test run to see if I can salvage the iPad.
You start by downloading the app from duetdisplay.com, after installing it on your Mac, you need to install the app on your iPad (you can use the same link), on your Mac it’s a free installation, on your iPad, it’s ±R200 you have to fork out for the iPad version of the app.
The first time you plug in the USB cable, it takes ages to startup, the app author also marketed it as lag-free, well, there’s definitely some lag, but not enough to make it unusable. The app starts up its own desktop and OSX sees it as a second screen.
You can use the iPad the same way as you would use the trackpad, some of the gestures work, others don’t, two finger scroll for example doesn’t work on the touch screen itself, you can control the cursor using the iPad’s touch screen, to right click on your iPad screen, just tap two fingers on the screen.
You can also swipe between your iPad apps and your second Mac Desktop (the second desktop is just the Duet App on the iPad), so if you have iPad apps running, swipe to your iPad app, and swipe back once you’re done to continue using your iPad as a screen.
If you take a full-screen screenshot, it takes two separate screenshots, one for your Mac and one on your iPad:
In terms of productivity, I can now develop on one screen and have my terminal on a second screen without having to jump around (the same benefits as a second screen, even though it’s a small screen)
Would I recommend it?
I’m already using it and loving it!
Update: I found a settings button that allows you increase the Frame Rate from 30 FPS to 60 FPS which makes it slightly less laggy.
