A global variable of type TScreen called Screen is created when you create a project. Screen encapsulates the state of the screen on which your application is running. Common tasks performed by Screen include specifying:

• The look of the cursor.
• The size of the window in which your application is running.
• A list of fonts available to the screen device.
• Multiple screen behavior (Windows only).

If your Windows application runs on multiple monitors, Screen maintains a list of monitors and their dimensions so that you can effectively manage the layout of your user interface.
