I am a video editor and I have seen 2-display video setups a where one monitor is used for the editing software, and the secondary monitor is used to preview the edited footage. How would I be able to set this up on an iMac, if at all possible?

What software do you use for editing? – jtbandes Nov 12 '12 at 1:00

The operating system supports multi screens. For the iMac i would say that a DisplayLink adapter would allow you to connect additional screens via USB. I've never used it, so I have no idea what the maximum resolution is, but I read several times on different boards that this solution has been successfully used.

Update: As gabesubdo mentioned in a comment below, it is not necessary to use a DisplayLink if your iMac has one or more Thunderbolt ports, which can be used as Mini Displayports as well. Apple provides adapters for Mini Displayports (to HDMI, VGA, ...)

DisplayLink is unnecessary here, the iMac has 1 or 2 Thunderbolt ports that can be used as Mini-DisplayPort for external displays. I don't understand the question, it's just a matter of obtaining a display and plugging it in. Mini-DisplayPort adapters are cheap and readily available. – gabedwrds Nov 12 '12 at 14:35
Good to know, thanks. I updated the answer. – cyphorious Nov 12 '12 at 14:55
