Hi Everyone. I have 2 iMacs, one is late 2010 and the other late 2011. I am using the 2011 but want to add the 2010 as a second monitor. Because one has a thunderbolt port and the other a mini displayport, will a mini displayport to mini displayport cable allow me to connect the two?
iMac 21.5″, macOS 10.13
Is the 2010 a 27" if it is not TDM simply will not work.

Dang! The 2010 is a 21.5" :(
Sorry, if you need an external display really, you can find them easily. New they start at $100 or so and I'm sure you can find a cheap used one.
Thanks for your help, much appreciated. The search for a monitor begins...
Target Display Mode no longer works on modern Macs. It's been this way for a long time.
Thunderbolt to Mini DisplayPort
