I'm connecting a flat screen tv to my laptop. The cable is connected and the tv screen now displays my desktop photo from my laptop. The display was being duplicated between my laptop and the tv screen however I wanted it to "extend" instead. So, I went in and clicked "Extend these displays" and I still can't minimize a window on my laptop and drag it over to the tv screen. So, my laptop is recognizing the second display but I can only duplicate on it I can't extend to it.
