the 14.1”/15.0”. If you set the resolution lower than this, the screen

desktop and select Properties to bring up the Display Properties dialog
box. Then click on the Settings tab to make sure that the resolution is
set to the appropriate resolution. Resolutions lower than the specified
resolution are not full-screen on the computer or on an external
monitor.
