Apple MacBook Pro 15 inch with 19 inch external monitor on OS X 10.8
It is very easy to hook an external monitor on MacBook Pro. All you need is the Mini DisplayPort to VGA Adapter, hook up and play with 'Displays' in 'System Preferences' to set it up to your liking. You can use the external monitor as a Mirroring monitor, or an additional monitor to left or right of the MacBook Pro or even top or below MacBook Pro as you will see on this brief demo.
