Hi Leon
My ASUS Laptop’s video card can support three modes. I can view stuff on the Laptop’s built in screen only, an external display only (such as a monitor or projector) or on both at the same time.
On my Laptop I use the 15 pin VGA connector on the side to connect the Laptop to the external display. The external display needs its own power from the display’s mains adapter as provided by the display manufacturer.
With everything powered off, I connect the external display to the Laptop via the 15 pin VGA connector and then power on the Laptop and external display.
On my ASUS Laptop I have to press some buttons (Fn + F8) to either view stuff on the built in display or view it on the external display. A more modern Laptop might automatically “sense” that an external display has been connected and switch to it automatically.
The correct Function Key (Fn) on your Laptop may have symbols showing an external display.
Some modern Laptops may use a DVI connector to connect the Laptop to the external display.
Hope that helps
Cheers
Dennis
