Hi Juan Out of the Box the iMac G5 does only video mirror. BUT It is because Apple disables this on consumer Macs Check out the patch on this site http://www.rutemoeller.com/mp/ibook/ibook_e.html It enables using extended desktop on modern consumer Macs I have personal experience with this and most new consumer Macs can extend their desktops after applying this OF patch. The iMac G5 is not listed as being tested so perhaps someone on the list with a G5 iMac could try it out and let us know if it works on a iMac G5?
