Windows 10. I want to compare two documents by putting each one on a different screen. I have got a second Monitor and connected it correctly. When I select and press: ' Window Button + P' the following options appear 'Duplicate', 'Extend', 'PC only', and 'Second Screen only'. If I press 'Duplicate' the display on both screens is identical (I don't want this). If I press 'Extend' I find my all the icons on the PC screen's desktop disappear (a blank desktop although the taskbar displays its icons); while the Second Screen shows this page (the Experts Exchange page on which I am writing this post). Any advice
In the "Customize your Display" settings you can select which of the 2 displays is your main display. The one selected as the main display will hold your desktop icons, as well as the main taskbar.
