Can I use my 27 Thunderbolt Display as a iMac or I need a cpu to run it?

Hello, so I have this apple 27 thunderbolt display and I'm not really sure how it works, I was told that a pc was already inside of the monitor that the only thing it was missing when they gave it to me was a controller to turn it on? I'm just a bit confused on how it would turn on and if there is another way too.


Serial #: ******


Please contact me to see if there is something I can do or if it needs a pc I would like to know


Thank you!

The Thunderbolt Display probably contains embedded computer circuitry. This would be like the computer circuitry built into a microwave oven or a USB keyboard – permanently dedicated to running the display, and not equipped to act as a general-purpose computer for running Mac, Windows, or Linux applications.


To connect one of these displays to a modern Mac, you'd need a $50 Apple Thunderbolt 3-to-2 adapter. A USB-C (male) to Mini DisplayPort (female) adapter would not work – the connectors would fit, but the adapter wouldn't be able to provide the kind of input that the Thunderbolt Display needs.


I could be mistaken, but I believe that the Thunderbolt Display does not have "hardware" menu controls … and that Apple never released software for adjusting brightness from any computer other than a Mac.
