    Hey all. I have a 27 inch iMac ATI Radeon HD 4670 (256mb) and I also have two 20 inch cinema displays. How can I connect both of these displays to iMac so that I have three in total (the iMac monitor plus the two 20 inch cinema displays)?

    Thank in advance for the help.

    The video on an iMac will only drive one extra monitor.

    If you want to add the second, you'll have to look into a USB video solution, like the NewerTech's that MacSales sells. Generally not as fast as the native displays but as a third monitor, who cares? Use it for your most static windows.
