Using Both a Monitor and Your Computer Display

You can attach an external monitor or projector to your computer and use it as an extension of your display (known as dual independent display or extended desktop mode). This mode allows you to use both screens independently and drag objects from one screen to the other, effectively doubling the amount of viewable work space.

To use extended desktop mode, perform the steps in the following section that corresponds to the operating system your computer is using.

NOTE: If you choose a resolution or color palette that is higher than the display supports, the settings adjust automatically to the closest supported values. For more information, see your operating system documentation.
