Hi all, so my home setup is 27" imac plus a dell monitor (hook up via mini displayport). I recently acquired a job that provided me with a mbp. I would like to hook up my mbp to both my imac and dell monitors. I bought the tb cable and tried hooking them up. mbp ->tb -> imac -> mini displayport -> dell. but this doesnt work. when imac went to the display mode, the dell monitor didnt. It remains as the "imac" monitor. Does anyone know how i can make this work?
