Ask HN: Make Thunderbolt 3 to 2 target display mode work?
I see posts on HN with very talented people who can deep dive into very low level hardware/software so I'm wondering would it be possible to prevent thousands 2011-2014 27" iMacs from ending up in landfills by making target display mode work with newer USB-C MacBooks [Thunderbolt 3 to thunderbolt 2 adapter](https://www.apple.com/ca/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter)?
FYI these are iMacs that have Thunderbolt ports instead of Displayports. There's already a way to do this with < 2011 iMacs with Displayports.
Things I've already tried, but the experience is not great: - used NoMachine and dummy HDMI - Installed Monterey on the 2012 iMac and use it as an airplay receiver - used tools like [Deskreen](https://github.com/pavlobu/deskreen)
