I have a Toshiba NB300 laptop with Windows 7 and it has one monitor port on the side.

I've have tried plugging in another monitor but it wont let me dual screen (ie 2 independent displays).

I can only do one screen or the orther, or duplicate screen.

Do I need to do something special to get dual screen? Is it just a limitation of my laptop?

Have you verified you have the latest graphic drivers and all Windows updates? – CharlieRB Apr 11 '13 at 19:50

This requires settings to be changed both on the laptop and in Windows 7. Once you get duplicate displays, you need to set Windows 7 to extend your desktop.

Here are some instructions how to do what you are asking;

Dual monitor setup: Two monitors are better than one

thanks i've done all that. but on that that drop down list where it should say 'extend displays' - it doesnt. i just have 'duplicate these screens' 'Show desktop only on 1' 'show desktop only on 2' – Lan Apr 11 '13 at 19:25

Understood. It's no problem. I am just letting you know for future posts. There is great information in How to Ask to help you. – CharlieRB Apr 11 '13 at 19:49
ok. thanks. but regarding my screen... can you help? or is it really just a limitation of my little laptop? thanks – Lan Apr 11 '13 at 19:58

try holing down the FN key at the bottom of the keyboard and press the F5 key to toggle dual screen options. Laptop option not windows 7 ;)
