I just had a quick question about dual monitors. I have vista home premium 64bit and am on a laptop. i hook up my laptop to my hdtv through a hdmi cable and i can get the dual monitor thing to work. When i am watching a movie, my laptop screen just sits on the desktop which is fine but I am worried about the screen possibly burning in if i keep watching movies. Is there a way i can put my laptop screen to sleep or on a screen saver without doing the same for the tv screen which is what the movie is playing on???? any help would be appreciated. thanks.
