I take it from the configuration of the new imacs that the option to have a second display running on my imac has disappeared, is there a work around for this?
No, that is an incorrect assumption. The current (late 2012) iMacs can support external displays just like the models before. If you want to get Thunderbolt displays I believe up to 4 externals and with other (DVI, VGA or HDMI) 2 displays. The non-Thunderbolt displays will require adapters (Mini-Display Port to DVI, VGA or HDMI) to work.

my problem is similar -- I have a macbook pro (late 2011) running mountain lion 10.8.2.
The display options screen does not have buttons for either the detect displays or arrangements(tab).
Is this a problem with mt. lion?

No the problem is probably that you are probably not using a high quality connection or didn't follow Apple's instructions for installing a second display. I would first try the latter and then the former. Here is a link to Apple's instructions. How to use multiple displays with your Mac ⁃

On my 15" retina MBP those options are not showing up until I actually plug in a monitor.
Did you try that ?
Looks like a feature. I.e. "don't show options until they actually can be used for something".

I'm using a brand new hdmi cable (works fine with my pc!) and a belkin thunderbolt adapter.
Please don't insult me by assuming I didn't follow the instructions-- which include using the tabs that don't appear!!!
Yes, I connected the tv as instructed. Unfortunately the problem is that the tv doesn't recognize the macbook pro and, yes, I did try both of the solutions -- plugging in the connection before powering up the computer, and putting it to sleep and then making the connections. I usually try any and all suggestions before posting a request for help.
As I stated above, the cable works fine with my acer laptop. The only difference is that I need the adapter for my macbook pro - and purchased one from Belkin. It fits perfectly and the connections are secure and tight. I cannot choose the detect display, since it is not there. I cannot choose the arrangements tab, since it is not there, either.

To rule out possibilities, can you try your setup with a different second screen to see if it works?
If you or someone you know has a computer screen with hdmi in, try with that screen instead of your tv.
If it works with that screen, then you know that your cable and adapter are working fine and the problem is with your tv having problem detecting the signal from the macbook.
If it does not work with the second screen, then the problem can be with the adapter or the cable.

njhorn: my answer was not directed at you, but the OP. No insult intended.
A quick google search and confirmed on my system:
Enter display preferences
press opt key
and the detect displays button appears

Well considering you're critical of my suggestions and obviously know better than I, but can't figure out this isn't even the correct forum (this is an iMac forum not a Macbook Pro forum) I'm done with you.
Good luck sport.

actually, it was not your suggestions that offended, it was your assumption that I probably did not follow directions.
as for the forum - sorry, I guess apple people are not as flexible as pc people. I did a search for my problem and this came up. It seems apple didn't recognize the macbook pro reference. (And, no, apple is not my choice - but it is required for both my job and my master's program.)
Thanks for replying, at least. btw, another suggested using the option key to get the detect displays button, which did work for getting the button.
