External Displays Not Supported
Connecting an external display to the iMac is not supported by
Apple. The db-15 port on the iMac was not designed to support
an external monitor. Apple designed iMac with a very sharp,
15-inch internal display and no video-out port to connect a
second display.
Refer to Tech Info Library (TIL) article #43016, “iMac: Can I
Attach an External Display?” for more information.
