So you want to use your iPad or other tablets as a secondary display for your computer? PIXO can help. It is a simple mount that lets you attach your tablet to your display to get more done. It supports tablet sizes from 7.9 to 12.9 inches. To get started, simply put two metallic stickers on your monitor and attach another on the back of your tablet.
PIXO lets you use your iPad Pro to extend your screen (using apps like Duet Display). Since it does not lock your tablet, you can grab it when you are done fast. The project is on Kickstarter at this time.
