Attached monitor not displaying duplicate in full screen

I have attached an LCD monitor to my laptop. But when the display is duplicated the monitor does not show in full screen. Instead it shows the same in a reduced screen. I cannot find any setting which would enable full screen. Please help.

press Windows + P key and choose to extend the desktop to the external monitor instead of duplicating laptop screen. the resolution on the external monitor will be automatically adjusted according to its optimised setting.

Why do you want me to extend the desktop? My problem is in duplicate mode.

this is to test if your monitor can switch to its optimal resolution and what the size is.

if the monitor works well in extended mode, then it means your laptop's resolution is not adjustable for the monitor, you have to let your laptop to fit with the monitor instead of vide versa.

to do this, press the screen switch key (FN + F?) on your laptop's keyboard to turn off laptop's screen and use external monitor only. this will make sure the external monitor work in its best resolution.

I know that too. I am sure there is nothing wrong with the laptop as it works well on another monitor.
