Thunderbolt to Mini DisplayPort

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

Connect two 2017 iMacs through thunderbolt 3 Is it possible to use a 2017 21.5 as the secondary monitor to a 2017 21.5 retina 4k. I am aware you can share a mouse and keyboard between the two, but I'm unable to drag windows from one screen to the other. I've only found 1 video stating to connect a thunderbolt 2 to a thunderbolt 3 by selecting CMD F2 on the 2nd keyboard but this doesn't appear to work for two thunderbolt 3 connectors. Any help is appreciated.

Is the 2010 a 27" if it is not TDM simply will not work.

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.

Target Display Mode no longer works on modern Macs. It's been this way for a long time.
