Resolved How to use my 2009 27" iMac as a second1 display?

[Obioban]

So I'd like to use my old 2009" 27" iMac as an external display for my newer iMac. I assume this is possible, as I've seen people do it with a macbook. But, when I plug it into my iMac, nothing occurs.

Is it because I'm using a thunderbolt cable instead of a mini display cable?

If so, and I buy a mini display port cable, how do the computers decide which is the computer and which is the display?

Thanks!

Since you have an iMac without Thunderbolt, you would need a Mini DisplayPort cable.

that link doesn't seem to work.

Mini DisplayPort cable is an easy fix. Any idea how to assign which iMac runs the show?
