Is there any way to connect two late 2014 iMacs together, to use one as a second screen?

I have two late 2014 iMacs. I would really like to use one as the computer and the other as the display. Everything I read says you can only do this with older iMacs. I find I hard to believe that a pre late 2014 iMac would have this technology but not a late 2014.

Is there any possible way to do this?

Thank you
