old iMac as dual monitor

I have a 2006 iMac running (and unable to run more than) 10.11 - its is still a beautiful screen and I want to use it as a dual monitor for my 2016 MacBook Pro. I have a thunderbolt to HDMI cord running to it with an HDMI to miniDisplayPort but it is not able to see it. What do I need to do differently?

thanks

iMac, OS X 10.11

It can't be done.

Use your iMac as a display with target display mode - Apple Support
