|the iPad is running at 60fps|
How about extending the display of your Windows 10 PC or MacBook into a secondary display without needing to pay for a second monitor? That's provided you have an iPad around. With DuetDisplay (RM60 iOS app, desktop app is free), you can do just that! And a secondary display is something that once you have it, you can't live without it. And using an iPad made it so much practical to carry around another display on-the-go, with your MacBook, to work! Try it out!
DuetDisplay just requires an iOS app, a desktop app that's super easy to install and the normal Lightning charging cable that came with the iPad. Connect the cable between the iPad and the USB port of the PC/Mac and you get high resolution, 60 FPS (!!) secondary display that DOES NOT LAG at all.
P.S. and if you connect to the Mac, the iPad can be used to display a TouchBar - you know, that nice new row of icons you can punch on your keyboard to do different things? Very nice!
