I would like to use a mid-2011 iMac as an external monitor

I would like to use a mid-2011 iMac as an external monitor for a 2019 iMac. The 2011 has a mini display port (with lightening bolt). The 2019 has a Thunderbolt (looks like a USB-C). I ordered a cable with one end a USB-C and the other a mini-display port but this evidently doesn't work. But I cannot seem to find a true cable that is Thunderbolt -> Mini Display Port.


Any suggestions?


Thank you.

In theory it should work per Use your iMac as a display with Target Display Mode however you will note Apple no longer supports that so then it again it may not. What I tell folks is that Macs are computers and not external displays for other computers. If you really need an external display for your 2019 then buy one.
