Well, that's one way to add a monitor to your Mac mini setup.
The folks over at Astro HQ, the developers behind Astropad, have come up with a novel use for Luna Display, the company's hardware module that turns your iPad into a full wireless touchscreen display for your Mac. By plugging Luna Display into a Mac mini and opening the Luna Display app on the new iPad Pro, Astro HQ was able to get the iPad to serve not as a secondary display for its Mac, but a primary one.
With this setup, you can control macOS using touch and Apple Pencil, just as you would anything else on your iPad. You can also use a keyboard and mouse, as you would with any Mac. From Astro HQ:
Of course, you don't need Apple's latest iPad Pro to do this with your own Mac mini, but with its symmetrical bezels on all four sides, it certainly makes a handsome small display for your Mac. But if you have an older iPad or iPad Pro, that should work fine, too. But no matter which iPad you use, you'll now have a touchscreen serving as your Mac's primary display, one that you can take with you all around your workspace. If you've ever wondered what it would be like to have a macOS tablet, this is the closest you'll probably get to that exact experience.
If you have Apple's new Mac mini and an iPad, you can try this out yourself. All you need is Astro's Luna Display hardware, as well as the companion app. You can find the Luna Display on the App Store for free:
As for the Luna Display hardware, it comes in two versions: USB-C and Mini DisplayPort. For the new Mac mini (and Macs released since 2016), you'll want the USB-C version. You can pick it up for $79.99 directly from Astro HQ.
