Sony VAIO VGN-A700 Series User Manual page 39

When an external display is connected to your computer, the Magnify screen button is disabled.
The magnified view is not as clear as the standard view.
Pressing the Magnify screen button changes the resolution, thus may cause a defect to any running software that does not support change in resolution.
Make sure to quit such software before pressing the Magnify screen button.
The Magnify screen button may not work with graphic images because it magnifies the screen view by changing the resolution.
The location and size of software windows may change when the screen view is magnified or when the standard view is restored.
When the LCD screen view is magnified, switching the view to the external display disables the function and restores the standard view.
