Hi, first time poster so please be gentle with me I'm a geriatric. My regular Mac is a Mac Mini, however I decided to buy an iMac 27 inch mid 2010 model which I am enjoying. However with my Mac Mini I used dual monitors and got used to having loads of acerage i.e. Skype on one screen whist doing oter stuff on the other. The problem now is this, the 2010 on has four USB and one firewire out puts. Can anyone set me straight with a workaround to get my other monitor to work with the current set up. Thanks in advance and hope I haven't broken any conventions.
