I have an early 2009 iMac (24" version). It has a mini display port in the back. Is it possible to use it as an external screen? If so, how do I do it? And can I attach all kinds of devices, e.g. a Raspberry Pi (with an appropriate adapter cable)?

The specifications for the 24" Early 2009 iMacs according to eveymac.com and the Apple Manual for the Early 2009 series of iMacs does not mention target display mode as a feature. That unfortunately means that the Early 2009 generation of iMacs did not offer a target display mode so you will not be able to use that displayport output as an input source. |

Check in the user manual for your particular model for Command-F2 as a shortcut to enter target display mode. If yours has a target display mode, you are good to go. If not, then no. I don't think that any 24-inch iMac model supports this. Initially the 27-inch models had this feature and later it trickled down to the 21-inch models. |
