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!

Luna Display - The BEST
Luna Display is the best thing that’s happened for Mac. I brought a M1 Macmini and a LG monitor. I was going to sell my old 2013 Imac but now thanks to Luna Display I can use my old Imac as a second screen. Win win for a very reasonable price. Highly recommend. Works seamlessly with Logitech keyboard and mouse.

Works as advertised
Works as advertised - best with Ethernet cable - great to have the iMac 27" 5K display back.

Extending the life of an old iMac
When Apple dropped support for target display mode for Apple silicon based macs (as clients) I thought I’d have to replace my trusty iMac with a new display, but the Luna display gives it a new lease of life, and keeps that gorgeous 27” display alive. Sadly not so compatible with my office VPN solution so I can’t just plug and play with office M3 based MacBook Pro and personal Mac Studio. I’ve yet to play with Astropad but sounds like fun having a tablet for my Mac.
