When your Windows PC is connected to a projector, TV or other external display several options are available that change how the image is displayed on your PC and/or external display.
The available options are:
- PC screen only: only use the original PC/Laptop display – the external display will be blank
- Duplicate: used to display the same image on both displays
- Extend: used to extend the desktop UI across the two displays; making your computer screen ‘longer.’
- Second screen only: only use the external display – the original will become blank
The display mode can be selected by pressing Windows Key + P on your keyboard, once the menu below is displayed keep the Windows Key held down and press P to cycle through the options.
