If you have the inclination and skills, it can be converted to an absolutely-zero-smartness display using an LCD driver board (this example conversion log used the A1419's housing with a separately purchased display panel): https://forums.macrumors.com/threads/diy-5k-monitor-success....

Absolutely do this. I built one and use it connected to a MacBook Pro. Building it was straightforward and 99% plug-and-play.

Someone needs to turn iMac-to-monitor conversion into a small business. At least in major cities, since packing up an iMac for shipping is not easy or fun if you don't have the original box anymore.

Very interesting! How much did it cost you?

It was about $250 all said and done. I got lucky and got the iMac for free, though even if I had purchased the Mac it would still be more affordable than Apple's Studio Display.
