dual screen video card

[Krash55918]

I do have two boxes available...I check the number two box and it changes the size of everything on my desk top...but I still cant get it where the words for the music are taking up the whole screen on the television unless I double click on the words on my puter screen...then I cant preload songs because I cant see anything but the words on my puter screen...is this normal or is there something I am not doing?...
