In case you're itching to use that new 27" iMac as a big display for a MacBook, DVD player, or some other device -- and assuming your new unit isn't one of the ones that has shown up DOA or with a cracked screen corner -- Apple has released a knowledge base article gives you the scoop on how to do it all.

The article, titled "Using a 27-inch iMac as an external display" outlines how easy it is to accomplish this:

1. Make sure both computers are turned on and awake.
2. Connect a male-to-male Mini DisplayPort cable to the Mini DisplayPort on each computer. The 27-inch iMac will enter Target Display Mode and display content from the source computer.
   Note: If you are connecting two 27-inch iMacs, connect a Mini DisplayPort cable to each computer and press Command + F2 on the 27-inch iMac keyboard that you will use as an external display.
3. To leave Target Display mode, press Command + F2 on the keyboard of the 27-inch iMac that is in Target Display mode. To return to Target Display mode, press Command + F2 again.

The post goes on to describe special conditions that may affect use of Target Display mode, and notes that third-party converters may be used to provide the Mini DisplayPort compliant signals needed for this mode.
