Luna Display by Astropad

Awesome

Bought the Luna Display to use my old 2013 iMac as a screen for my new MacBook, works so well, great little gadget and would highly recommend. great service too, fast shipping.

No good if you're a designer

The delay/lag on the second screen makes the device virtually unusable. It's only fine for reading emails at best. Every time you move the mouse, there's a resolution. delay.

This is actually quite cool

But it should be software and not need a dongle - a thunderbolt cable should be enough... and the iMac should be able to become a hub as well... but as far as making use of the gorgeous screen in an old intel 27" iMac - this brings the machine into 2025, and keeps it humming!
