My screen can't expand between two screens?

So, I just now got my VGA cable and plugged it into my Monitor, then my laptop. So I go to screen resolution where it shows 2 screens, and click "extend" but whenever I do that and apply it, my monitor just shows my desktop picture. I tried every single resolution. Still nothing anyone know what to do?

your spec says 'Antivirus AVG & MSE'. Should only use one or the other. Two together ain't recommended.

Monitors - try Windows key + P : this lets you select mirror, extend etc. see pic
