So, in 2007 I received a 17in iMac for my Birthday, then in 2010 I won a Macbook 13 inch from my school, so my dad made me give my iMac to my sister. Well yesterday was her birthday and she got a 13 in macbook pro. So I got my iMac back. Well before christmas, I bought my self a Mac Pro for Final Cut Pro and some heavy duty processes. I really don't have any use for the iMac, and I'm not going to get very much for it if I were to sell it because my sister some how managed to have it fall of her desk. It works, it just has some wavy lines on the side it feel on. Nothing to managed, God help that Macbook she got, I hope it lastes longer then her phones. So I'm thinking I can use it as a secondary display, can anyone tell me how one might go about doing it?

Because only they have the needed Target Display Mode. Target Display Mode is when you connect an external device to the iMac's mini-DisplayPort. Any other non-27" iMac does not have the needed wiring or software to make it work.

Apple did nothing wrong. The technology to be able to have an iMac with Target Display Mode didn't exist in 2007.

It's also "only" a 17" display. You can get cheap 22" 1080P monitors for only about $100 anymore which will use a lot less power (since even if it did have target display mode you would have to leave on your iMac at all times to use it) and give you more resolution and size.

Forgot about this solution: If you really want to do the above, you could use this:

I tried it for awhile. It does work. a little laggy, but it does work.

yes you can...

First, it cannot be used in target mode because the 2007 minidvi is video out only.

But, if you share the screen of the 2018 mac, it works like a charm.

I wanted a second external monitor. I connected the first monitor thru the hmdi of the mac laptop (iogear) dock. For the the second external monitor (2007 IMAC) I just shared the primary screen of the laptop, then 'connected' to that laptop from the iMAC, and wow, there it is. 2 external screens, the reuse of your beautiful 2007 MAC screen, and you can still use the laptop screen per usual.

Your welcome.

hi,

I have two iMac 2007 and wanted to use them as screens with my MacBook Pro 2016 but I am confused what method you followed. Is it possible to give a step by step guidance with bit more details.
Thank you so much in advance.

As stated in the posts above,
1) connect one monitor via HDMI cable - done here...
2) connect 2nd monitor wirelessly,
- go to laptop settings , sharing, check screen sharing
- go to iMac,
do one of the following:
  • Connect using the name: Click the Finder icon
    in the Dock to open a Finder window. In the Locations section of the sidebar, click Network, double-click the Mac you want to share, then click Share Screen.
    If no items appear in the Locations section of the sidebar, hold the pointer over the word Locations, then click Show.
  • Connect using the address: In the Finder, choose Go > Connect to Server, enter the address of the Mac you want to share, then click Connect.

Hello
I am wondering I have done this but now it just mirrors my Mac book . How do I get it to be a secondary screen where I can flip between and use both?
