I have a 27in i5. I am looking for a bit more screen real estate(day trading, graphic editing, etc.). I know that in theory these iMacs can only be hooked up to one additional display via the mini display port. However, in my search to find monitors that would look good next to the beautiful iMac - I found this little unit. It is called a CinemaView Duo and I guess I would plug this into the iMac 27 mini display port, giving me two more. Could I then hook up two of these to the Duo unit and get the triple screen setup I am after? I would like to have the iMac situated in the middle for aesthetic purposes, but I am not sure this can be done. Does anyone have any suggestions/ideas/comments? Thanks!
