Extending desktop by adding second monitor?
At work we use a thin client with dual monitors. I can access this from home on my 24" iMac (early 2008) using the Remote Desktop Connection included with Office 2011. I would like to add a second monitor to my iMac so I can more closely duplicate my work setup. This would involve spreading that one window across both my iMac screen and the second monitor screen. Is this possible? If so, are there recommendations regarding specs on the second monitor and the optimum way to connect it? Thanks for any suggestions.
iMac, OS X Mountain Lion (10.8.3)
