Duel monitors, which adapter?

I've got a 2010 iMac, which I want set up with a linked monitor for multitasking purposes.

I suppose my first question is: can my 2010 model support that?

My second question is, what adapter do I use if possible? I have a "Mini Displayport" to HDMI-female lying around, but it doesn't fit the socket. I'm wondering that since my iMac is relatively old when it comes to tech that maybe it takes something different? I tried searching ebay and apparently there are two different port types, but according to the diagrams provided, it looks like I've got the correct adapter even though I clearly don't, unless I've got a faulty port.

Many thanks,

Solved.

Someone mentioned in an old thread that their port was misaligned. So I checked mine with a magnifying glass and yep, so was mine. Had to force it in at an angle and use the connecter itself to actually leverage the port up. It took an incredible amount of force to push this **** thing in, so much I thought I was going to break it. But it's working!

Glad you were able to fix it. I was going to say that I'm pretty sure yours does use a Mini DP connector. I don't think any Intel iMacs use the other one (which is called Mini DVI)
