My monitor screen resolution changes depending on wether my laptop lid is open/closed. The lid being open has a lower resolution than being closed. Why is this ?
In control panel I have :
Laptop lid open :
Laptop lid closed :
If you choose to
Duplicate these displays, your computer has to choose a resolution that is supported by both displays.
If you cannot choose a higher resolution with the lid open, it means that
1024 x 768 is the highest resolution supported by your internal display. Obviously, this restriction does not apply when using only the external monitor.
